Arrhythmia: Does caffeine disrupt normal rhythms?

I experienced a temporary syncope while driving and totaled my car. No serious injury though. Local DR had me cut back on atenolol and the thought was I could be over-medicated as I take several other medications. Previous spells were shorter-lived and far apart.

Mayo put me on a heart monitor last year. This summer, (20011), They collected data from the implant and decided I had a heart aarrythma which probably triggered my fainting spells. I opted for minimal RX treatment as opposed to a pacemaker for a period of time to see if this corrected the problem. Next year at Mayo, maybe I'll have an answer. Pacemaker??

Thank you for the reply. Although thankfully my symptoms are arrythmia at this time, I did experience temporary syncope last year. Luckilly I wasn't driving at the time it happened. I do take many medications but up until lately haven't had any arrythmia. I did wear a 24 hour holter monitor about 2 months ago but nothing of note was recorded. But since then the irregular beats have gotten more frequent.

I'm going to my cardiologist next week for a nuclear stress test. I will tell him then about the more frequent arrythmia lately.

In a recent EKG my arrythmia beats are below normal, very slow. Mine are 48 beat per minute and normal is 60-100 beats per minute. Not sure how serious this is? Anyone else have a LOW arrythmia?

The caffine in coffee (chocolate and other sources) can instigate this. I have had this for years and have found that 300mg of Magnesium and 200 mg of CoQ10 have nearly eliminated the PVC's and PAC's. See a cardiologist for evaluation and reassurance
