Hi Worry Wart.

I am currently suffering from similar symptoms myself. I am having heart palpitation on a daily occurrence. These symptoms can be very scary. Although I have had similar symptoms in the past and was checkout (EKG, head scan, Chest-Xray, ultrasound on the arteries in my neck) and nothing was found. It still plays havoc with my mind.

I have schedule a echo to be done and will be wearing an holster for 24 hours to monitor me through out the day. I have never had these tests done. My doc told me if these test shows up negative then it is the anxiety/stress that I am feeling and I should work on reducing my anxiety/stress. So, I would say get whatever tests that needs to be done to ease your mind. When it comes to the heart error on the side of caution.

I was at the gym earlier and didn't experience anything, however as I was typing a response to you I had two palpitations. I believe me reflecting and going over my experience triggered me. Anxiety can be a terrible thing. I hope my comments helps you in someway.
