Welcome back to icliniq.com.
I have seen the attached (attachment removed to protect the patient's identity) reports. In my opinion, too, your ECG (electrocardiogram) is fine. Machine-generated reports are frequently inaccurate. With age and being overweight, some amount of left atrial enlargement might be there on echo, and it will be acceptable if it is there. However, there is no clear or definitive suggestion of left atrial enlargement on ECG. Besides, the accuracy of such findings on ECG is unreliable; an echocardiogram is a critical investigation. Upper chest heaviness persisting for a few days may be related to musculoskeletal causes. However, you can request further evaluation like an echo and stress test, and get prescription refill online, especially if there are additional risk factors like family history, etc., besides hypertension. You should focus on hypertension control, weight loss, and stabilization of the mind with the help of yoga, meditation, staying busy, reading books, etc. I hope this helps you. Thank you.
