There is a ton of information here. I've been studying heart palpitations since 2002 when I had my first attack. Like many others, I thought I was dying!
Since I'm already an online researcher, it was an easy step for me to ad "palp research" to my daily routine. It took me 6 years to nail down the risk factors for palpitations of my type. My doctor says my heart is fine and that I am just stressed and should lay off coffee etc. Lol. Wish it was that easy!
It took me nearly six years but I cured my problem. Now I blog about it and speak with others who want to know what I did. The answer is out there folks and its NOT drugs!
