Annoyed palpitations

[r9c]

Hi everyone,i just want to share my experienced on this palpitation so far,up to now i have done a stress test,echo,2x 24 hour holter,blood test and several ecgs,all came out okay,even for my holter too but i told my cardiologist during the 24hr holter test i felt lightheaded and dizziness and he say its not heart rhythm related because it might be just anxiety. So i asked him why do i still feel dizzy if all cardia test came out normal he just scheduled me for tilt table test next week,so any one of u had this tilt table test before?

Head up tilt tests are used to find out if your blood pressure drops when standing up. If it does, it's usually not caused by heart disease (and you've ruled this out since you had no arrhytmia during your lightheadedness, this must be a great relief).

When you're standing up, approx. 500 ml of blood drops down in your stomach and legs (due to gravity) and your body need to compensate by increasing heart rate, blood pressure, compressing blood vessels, etc. In some people, this process is a bit slow due to a minor nerve system dysfunction, and you get dizzy.

When you're driving a car, and you speed up too slow (by pushing the gas too late), you can't say it's an engine malfunction. It's the engine controller, you, that react a bit late. I hope this picture explained the situation :)
