Alone ECG report can not guide us to any diagnosis. If you have to clear the picture about PHA, you have to go for Echocardiography
. In which the actual pressure can be measured and decision can be taken whether needs medication or not. Feel free to consult your cardiologist and discuss it with him.
If you are worried for Coronary artery
disease than go for stress test
(commonly known as TMT). And if needed may go for Coronary Angiography
Hope you got your answer.
