Hello, several years ago I was diagnosed with PSVT and took medicine for a short period of time. I have had normal EKG's and Echo's since until I had an abnormal EKG this week. The technician kept telling me the waves were really big..up and down. She thought the machine might have been messed up. Finally, she was able to get a reading. It came back as sinus rhythm, left atrial abnormality, consider left ventricular hyperthrophy. Oh, I forgot to mention this Dr. did find a heart murmur also but stated that it hasn't changed since she first picked it up last year. My son has a heart valve problem that is not serious but requires a yearly checkup so we are both seeing the cardiologist next week. Any light you could offer for me, at this point? Thanks
