Patient's Query

Hello doctor,

I have recently been evaluated for palpitations. I had one ECG done that revealed I have abnormal ST and T waves. I was then asked to do a stress test. I also had a Holter monitor on for 24 hours. The stress test came back negative, and the Holter monitor came back normal. I then went to a second doctor to get a second opinion, and now the ECG report revealed that I have a possible left atrial enlargement. I have a copy of this ECG I was wondering if I could get a third opinion. I would also like to know if the ECG is an accurate way to diagnose left atrial enlargement. Kindly suggest.

Hello,

Welcome to icliniq.com.

Your stress ECG (electrocardiogram) report attached (attachment removed to protect the patient's identity) is perfect. No, ECG is not the perfect way to diagnose left atrial enlargement. There is always some reason for left atrial enlargements, such as the reduced opening of the mitral valve or leakage of the mitral valve. (Mitral valve is the valve between the left heart chambers and controls blood flow from the left atrium to the left ventricle and prevents blood's backflow that is leakage). To properly diagnose any of such abnormalities, I would recommend echocardiography. Kindly get it done and follow up if there is any abnormality. Thank you.
