... that you're like me. You have normal sinus activity, but that the electrical pathways to your ventricle are blocked. Your PM will sense the natural rhythm in your atrium and send a pulse to your ventricle.

Sounds like you have an AV block. Like heckboy said, you have a functioning SA node (in the Atrium) but the signal it sends can't always make it through the AV node to the Ventricle. My PM merely "senses" my atrial activity and then assists in getting the signal to the ventricle which it is doing about 50% of the time. Next time you go in for a PM check, ask if what you have is an AV block.


not confused any more

Many people have problems where the heart rate does not increase on its own and have a pm for that. The only person I trust with my pm questions (other then PM Club Members) is my EP. When I first got the pm the nurse in the clinic and the cardiologist went from bad settings to worse. I don't believe they knew how the features of the pm worked. The nurse told me the pm would control my lower heart rate and not allow my heart to beat over 145bpm. On the tredmill I hit 154. They turned off and on all sorts of functions. The EP shut everything down and I just have my lower rate set at 70 bpm. My advice as always is to ask an EP!

I just want to share about the quality of life after my pacemaker, and hopefully increase awareness that lifestyles do not have to be drastically modified just because we are pacemaker recipients.
