Yes Just Had A Stress Test, Echocardiogram, And Heart Cath.

Yes just had a stress test, echocardiogram, and heart Cath. The Cath showed no blockage, the ekg went erratic and my systolic pressure went up to 146. The doctor thinks my heart has or had a virus my heart function is about 25%. I have had two heart attacks in the past with one having a stent inserted. He has put me on water pills along with my reg blood pressure and blood thinners. Wants to see if it improves if not wants to put in a defibrillator. Your thoughts?
