What do my ECG readings suggest?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I underwent an ECG test and received the results. Could you please help me understand them better and assess my heart health?

Rhythm analysis:

  • Rhythm irregularity: 6%

  • Average ventricular rate: 59 beats per minute.

  • Sinus bradycardia.

Contour analysis:

  • The electrical axis of the heart (EOS) is in a normal position in the frontal plane.

  • QT interval shortening excludes hypercalcemia.

  • Possible old septal myocardial infarction.

Please help.

Hi,

Welcome to icliniq.com.

I understand your concern.

Based on the ECG (electrocardiogram) report you shared (attachments were removed to protect the patient's identity), most findings are not dangerous, especially given your young age, but a few points require proper context and reassurance.

An average heart rate of 59 beats per minute with sinus bradycardia can be completely normal in young adults, physically active individuals, or during rest and sleep, as long as you do not have symptoms like dizziness, fainting, or extreme fatigue. The six percent rhythm irregularity is mild and often reflects normal sinus variability with breathing rather than a true arrhythmia. An electrical axis (EOS) within normal limits is a reassuring sign and indicates normal heart electrical conduction.

The note about a shortened QT interval simply means it is not prolonged, and hypercalcemia is unlikely, which is reassuring. The phrase "possible old septal myocardial infarction" is very commonly reported by automated ECG machines and is frequently a false positive in young, healthy people due to normal septal Q waves, lead placement issues, or normal variants.

At 26 years old, without a history of chest pain, heart disease, smoking, diabetes, or hypertension, a true old heart attack would be extremely unlikely. Overall, this ECG does not suggest an acute or dangerous heart problem, but the automated interpretation should always be confirmed by a cardiologist. If you have symptoms such as chest pain, shortness of breath, fainting, or severe palpitations, further evaluation, such as an echocardiogram or repeat ECG, would be reasonable. If you are asymptomatic, this ECG is most likely clinically normal.

I hope this has helped you.

Please feel free to reach out to me again for further queries.

Thank you.
