My journey started with Bradycardia after wearing 2 week heart monitor.
Some times slow heart beat can be normal for people in great shape.
After a stress test which I failed, I had to go to er .. dizziness, hard to catch breath, fatigue.
I had an angiogram (no stints needed) than a pace maker installed.
Am in recovery but no more dizziness and improving.
Parallel to this I was on hormone and chemo drugs for prostate cancer.
It can be impossible to separate symptoms and where they come from.
Tests for blood flow are not accurate.
