Hi, In my case I ended up with a diagnosis of CPVT (catecholinergic polymorphic ventricular tachycardia) which is passed on genetically. Estimated 1/10,000 people according to NYU website. Diagnosed after being defibrillated multiple times on the floor of the ER. Now I have pacemaker/defib for 10 years.
Not trying to scare anyone, they say most premature beats (which can be perceived as palpitations) are harmless. 20 years ago when they tried treating people who had palpitations from frequent PVC's they found the medications were killing people, so they stopped this treatment.
Of course palpitions can have many other causes, so try to find the cause. If it's effecting your life, get a second opinion (though if your blacking out and doing face plants don't waste too much time
I take magnesium, pottasium (morton lite and seasalt in water bottle, 162 mg aspirin (was breaking a generic alka-seltzer in half with water to prevent ulcer), fish oil, multivit, B and D vitamins.
I have been an ample beer drinker since 15 years old and when dx'ed at 38 had borderline low magnesium. I interpeted this as having pissed out ALL my electrolytes and minerals. Cut back on booze, (2 glass red wine)
Please don't take this as medical advice. Just my story.
I used to go to about.com heart disease website where cardiologist Rich Fogoros had excellent articles and forum.
