Detail:
This is when it all went to heck! Pounding, thumping in chest, felt like pressure on chest, some breathing issues. Went to cardiologist and he did several tests (echo, resting nuclear imaging, ECG), along with blood work up and scheduled nuclear stress test along with a double cardiac catheterization. A few days later symptoms got so bad, went to ER and they performed tests and concluded it was "just" PVC's. Eventually nuclear stress test came back ok, as all other tests did.
