Am a 51 yr old male. Was on vacation with kids and did some roller coaster type stuff! Afterwards, experienced pronounced flutter sensation in chest - not pain or tightness. This has been returning on a regular basis. Attended cardiologist and had a clear angiogram, echo scan and cardio stress test. Used a 24 hr haltor monitor but did not experience symptom during the test. The sensation is associated with exercise and is getting more pronounced. Could a rush of adrenalin (it was a scary ride) have caused some electrical damage to my heart which is not registering on any of the tests undertaken?
I don't think a rush of adrenalin would cause any electrical damage to your heart. But, it could bolster your anxiety and, in turn, set off some flip-flops (PVCs/PACs). In someone with a structurally normal heart, PVCs and PACs are considered benign. One thing that might help is to ask your doctor for an "event" monitor. You can wear it for a longer period of time (weeks) and press "record" when you feel something. That way, you'll be sure your doctor is "seeing" what you're "feeling."
