When a professional interprets an ECG saying that you possibly had a heart attack
in the past means that he found "Q" waves in the ECG, but Q waves which represent heart attack has characteristic appearance (based on criteria) which distinguishes them from "normal Q" waves.
If your Coronary Angiography
was normal, that means your risk of having had a heart attack is way too far (until and unless your heart attack was precipitated by "Vasospasm
= prinzmetal angina
, or you have Syndrome X).
Abnormal Q waves can also be found in the following conditions without coronary artery
1- Hypertensive heart disease
2- Hypertrophic Cardiomyopathy
3- Nonischemic Cardiomyopathy
4- Asymmetric septal hypertrophy
to exclude these possibilities follow two steps
2- Exercise Stress Test
