I had an ecg taken twice the past week and it showed non specific st t wave changes and the doctor told me to have sa stress test today. And to my dismay she said may stress ecg was abnormal with my heartbeat normal and my bp. She showed me the result but i can't understand what it means. She told me to do a stress echo next week, does that mean i have a heart problem? Or is there a chance that my stress echo could be normal? I am a seaman, and my work depends on the result of my stress echo. Is there any way to help me get a good stress echo result? Your suggestions will help me lot. Thanks
