Failure to Interpret ECG Results Medical Malpractice in Chicago

An electrocardiogram, or ECG (also called an EKG), is one of the most important tools a doctor has when a patient walks in with chest pain, shortness of breath, or unexplained fatigue. An electrocardiogram is a non-invasive test that records the electrical activity of the heart. Doctors use it to spot heart attacks, dangerous arrhythmias, and other life-threatening conditions. When a physician fails to read that test correctly, the consequences can be catastrophic. If you or someone you love was harmed because a doctor misread or ignored ECG results in Chicago, you may have a valid medical malpractice claim. The attorneys at Briskman Briskman & Greenberg, located at 205 W Randolph St., Suite 925, Chicago, IL 60606, are ready to review your case.

What It Means When a Doctor Fails to Interpret ECG Results Correctly

Failing to interpret ECG results correctly means a physician either misread the data the test produced, dismissed abnormal findings, or failed to act on clear warning signs. All three failures can cause just as much harm as if no test had been ordered at all.

ECG interpretation software mistakes can lead to incorrect diagnoses and inappropriate treatments, and the consequences of not recognizing such mistakes can result in stroke, cardiac arrest, and even death. Doctors cannot simply accept a computer-generated reading as final. Computer analyses of ECGs should be considered a helpful adjunct to, but not a substitute for, physician interpretation in clinical decision making.

One of the most dangerous scenarios involves a heart attack that does not show obvious signs on an ECG. STEMI (ST-Elevation Myocardial Infarction) typically presents with clear ST-segment elevation on the ECG, making it easier to diagnose, while NSTEMI (Non-ST-Elevation Myocardial Infarction) often has less obvious ECG changes, making it more challenging to detect and increasing the risk of a missed diagnosis. A doctor who sees a normal-looking ECG and stops investigating may miss a NSTEMI entirely.

A normal ECG does not rule out a heart attack, especially in the early stages or in cases of NSTEMI, and other tests like troponin blood tests are needed to confirm or exclude the diagnosis. Relying on one test alone, without looking at the patient’s full clinical picture, is a well-recognized failure in cardiac care. Patients who come to emergency rooms near Millennium Park, Northwestern Memorial Hospital, or Rush University Medical Center deserve a thorough evaluation, not a rushed read of a single printout.

Misinterpretation of ECGs can lead to inappropriate medical therapies, such as the use of antiarrhythmic drugs, beta-blockers, and anticoagulation, as well as increased resource utilization. These errors do not just delay care. They sometimes cause active harm through the wrong treatment being given.

How ECG Misinterpretation Causes Serious Patient Harm in Chicago

The real-world impact of a misread ECG is not abstract. Patients suffer heart attacks, strokes, permanent cardiac damage, and death when doctors fail to act on what the test is showing them.

A case reported through the Agency for Healthcare Research and Quality (AHRQ) illustrates how quickly things can go wrong. Emergency medical service providers obtained an ECG in a woman who had developed severe chest pressure at home, and the ECG revealed an ST-elevation myocardial infarction. Unfortunately, the ECG failed to transmit to the emergency department while EMS was en route, so a “Code STEMI” was not activated, and unaware of the original ECG results, ED clinicians obtained a repeat ECG that did not demonstrate the earlier ST segment elevations.

Because treatment had been delayed for many hours from the time of the original STEMI, the patient experienced significant loss of cardiac muscle function and ultimately required placement of a device to assist her heart function and a prolonged stay in the cardiac intensive care unit. That kind of delay, caused by a failure to communicate and act on ECG results, is exactly the type of negligence that forms the basis of a medical malpractice claim in Illinois.

ECG misinterpretation also connects directly to failures involving arrhythmias. Inaccurate lead placement, inappropriate serial comparisons, lead wire reversals, and excessively noisy signals can lead to errors in ECG recording. These are technical errors that trained professionals are expected to catch and correct. When they do not, patients pay the price.

Chicago residents who receive care at busy emergency departments along the Lake Shore Drive corridor or in neighborhoods like Wicker Park, Logan Square, or the South Loop deserve the same standard of care as patients anywhere. A missed ECG reading in a high-traffic ER is not excusable because the department was busy. The standard of care does not bend for workload.

Illinois Law and What You Must Prove in an ECG Malpractice Case

Illinois medical malpractice law sets specific rules for how these cases must be built and filed. Understanding those rules helps you know what to expect and why acting quickly matters.

Under medical malpractice lawyer guidance, the foundation of any ECG malpractice case is proving four things: the doctor owed you a duty of care, the doctor breached that duty, the breach caused your injury, and you suffered real damages. In ECG cases, the breach is typically the failure to correctly read, communicate, or act on the test results.

Before your case can even be filed in an Illinois court, the law imposes a pre-filing requirement. Under the Illinois Code of Civil Procedure, Section 735 ILCS 5/2-622 (the Healing Art Malpractice Certificate of Merit), your attorney must attach an affidavit to the complaint stating that a qualified health professional has reviewed your records and determined there is a reasonable and meritorious basis for the claim. That reviewing professional must be knowledgeable in the relevant area of medicine and must have practiced or taught in that area within the last six years. This requirement exists to screen out frivolous claims, but it also means your case needs to be supported by a credible medical expert from the start.

Illinois also sets strict deadlines under 735 ILCS 5/13-212. An Illinois medical malpractice action generally must be brought within two years after the claimant knew, or through reasonable diligence should have known, of the injury or death for which damages are sought, but there is usually a four-year outside limit from the act or omission. Missing either deadline can bar your claim entirely, regardless of how strong the facts are.

Expert witness testimony is also required under 735 ILCS 5/8-2501, which sets standards for who can testify about the appropriate standard of care. The expert must have a relevant specialty, must have devoted substantial time to practice or teaching in that area, and must be licensed in the same profession as the defendant. In ECG malpractice cases, that typically means a cardiologist or emergency medicine physician who can explain to a jury exactly what the test showed and what a competent doctor should have done with that information.

Damages You Can Recover in an Illinois ECG Malpractice Claim

When a doctor’s failure to interpret an ECG correctly causes serious harm, Illinois law allows injured patients to seek compensation for the full scope of their losses. These damages fall into two broad categories: economic and non-economic.

Economic damages include medical bills, future treatment costs, lost wages, and the cost of long-term care. If a missed heart attack required bypass surgery, a defibrillator implant, or extended rehabilitation at a facility near the Medical District on the Near West Side, all of those costs can be part of your claim. Lost earning capacity matters too, especially if the cardiac event left you unable to return to work.

Non-economic damages cover pain and suffering, emotional distress, and loss of a normal life. Illinois does not cap these damages in medical malpractice cases. Under 735 ILCS 5/2-1115, punitive damages are not available in healing art malpractice claims, but compensatory damages for economic and non-economic harm remain fully recoverable without a statutory cap.

If a patient died because of a misread ECG, surviving family members may bring a wrongful death claim under the Illinois Wrongful Death Act, 740 ILCS 180/1. This statute allows the person’s estate and family to seek damages for the loss caused by the negligent act. Wrongful death claims in medical malpractice cases are generally subject to a two-year statute of limitations measured from the date of death, with the four-year statute of repose under 735 ILCS 5/13-212 still applying as an outer limit.

Under 735 ILCS 5/2-1114, attorney fees in Illinois medical malpractice cases are capped at 33 1/3% of all sums recovered on a contingent fee basis. This means you do not pay attorney fees unless your case results in a recovery. However, clients may still be responsible for case costs and expenses separate from attorney fees. Ask about this when you consult with a medical malpractice attorney so you fully understand the financial terms of your representation.

Common Situations Where ECG Misinterpretation Leads to Malpractice Claims

ECG malpractice does not always look the same. Several distinct patterns of error appear repeatedly in these cases, and recognizing them helps patients understand whether what happened to them may rise to the level of negligence.

One common situation involves a doctor dismissing abnormal ECG findings as insignificant. Electrocardiograms and blood tests used to diagnose heart attacks can occasionally be misinterpreted, and subtle abnormalities can be missed or written off as non-cardiac in nature. A physician who sees an unusual reading and attributes it to anxiety or acid reflux without further testing may be falling below the standard of care.

Another pattern involves relying entirely on automated ECG software without physician review. Physicians must have sufficient knowledge to understand and accurately recognize the basic pathophysiology of electrocardiographic abnormalities. Letting a computer make the final call is not acceptable medical practice. A trained medical malpractice lawyer can work with cardiac experts to show the jury exactly where the physician’s review fell short.

A third situation involves ECG results being filed in the wrong patient’s chart. Multiple ECGs have been incorrectly documented at large urban hospitals, with nurses or ECG technicians either entering the wrong medical record number or not clearing the previous patient’s information from the machine, causing ECG results to be uploaded to the wrong patients’ charts. This type of systemic error can delay care for the patient who actually needed it.

Failure to follow up on an abnormal ECG result is also a recognized basis for malpractice. A doctor who orders an ECG, sees an abnormal reading, and then refers the patient for a routine outpatient appointment rather than urgent cardiac evaluation may be creating a dangerous gap in care. This connects closely to broader failures involving delayed referrals and the failure to communicate critical test results, both of which are serious concerns in cardiac care settings across Chicago.

If you believe any of these situations applies to your case, speaking with a medical malpractice attorney promptly is essential. The two-year clock under 735 ILCS 5/13-212 starts running when you knew or should have known of the connection between the error and your injury.

FAQs About Failure to Interpret ECG Results Medical Malpractice in Chicago

What qualifies as malpractice when a doctor misreads an ECG?

A doctor’s misreading of an ECG qualifies as malpractice when it falls below the accepted standard of care and directly causes patient harm. This means a competent physician in the same specialty, under similar circumstances, would have read the ECG correctly and taken appropriate action. Simply making a mistake is not enough on its own. You must show that the error caused a specific injury, such as a delayed heart attack diagnosis, a missed arrhythmia, or a failure to refer the patient for urgent cardiac care. Illinois courts require expert testimony under 735 ILCS 5/8-2501 to establish what the standard of care required in your specific situation.

How long do I have to file an ECG malpractice claim in Illinois?

Under 735 ILCS 5/13-212, most adults have two years from the date they knew or reasonably should have known that a medical error caused their injury. There is also an absolute four-year deadline from the date of the negligent act, regardless of when you discovered the error. These deadlines are strict. Missing them typically means losing your right to sue, no matter how serious the harm. If the patient was a minor, different rules apply under 735 ILCS 5/13-212(b), which allows up to eight years from the act of negligence but not past the person’s 22nd birthday. Contact an attorney as soon as possible to protect your rights.

Can I sue if my doctor relied on a computer ECG reading that was wrong?

Yes, relying entirely on a computer-generated ECG interpretation without applying independent physician judgment can be a basis for a malpractice claim. Published research in the Journal of Electrocardiology confirms that ECG interpretation software can produce incorrect diagnoses and inappropriate treatment recommendations. Physicians are expected to use their own clinical knowledge and consider the patient’s full medical picture, not just accept an automated output. If a doctor accepted a faulty computer reading without question and you were harmed as a result, that failure may support a malpractice claim under Illinois law.

What damages can I recover if a misread ECG caused a heart attack or cardiac injury?

You may recover both economic and non-economic damages. Economic damages include past and future medical bills, rehabilitation costs, lost wages, and lost earning capacity. Non-economic damages include pain and suffering, emotional distress, and loss of a normal life. Illinois does not cap these compensatory damages in medical malpractice cases under 735 ILCS 5/2-1115. Punitive damages are not available in healing art malpractice claims in Illinois. If a family member died because of a misread ECG, surviving family members may seek damages under the Illinois Wrongful Death Act, 740 ILCS 180/1.

What should I do first if I think a doctor misread my ECG and caused me harm?

Start by gathering all of your medical records, including the ECG printout, any physician notes, lab results, and records of follow-up care. Do not rely on the hospital or doctor’s office to preserve this evidence on your behalf. Then contact a qualified Illinois medical malpractice attorney as soon as possible. Illinois law under 735 ILCS 5/2-622 requires that a health professional review your records and certify the claim before it can be filed. That process takes time, so starting early is important. Call Briskman Briskman & Greenberg at (312) 222-0010 for a free consultation. The firm is located at 205 W Randolph St., Suite 925, Chicago, IL 60606.
