Hi everyone,
My big HA is all about my heart and whether I have some undiagnosed heart condition. I have had a ECG and blood tests and had two different doctors listen to my heart and all came back as fine.

However, every time I run up stairs or even do the smallest of tasks around the house, my heart seems to beat really fast and hard. If I stop and sit down, it returns to normal quite quickly though. I don't get any other symptoms such as light headedness or dizziness when this happens.

I have read about something called Ventricular Tachycardia and how it is a major cause of sudden death. I was just wondering what exactly is Ventricular Tachycardia? If you had VT, would it be constantly present or is it possible for it come and go? Does what I am experience sound like it could be VT?

Any advice would be fantastic!
