biotronik pacemaker

I had a pacemaker installed a year ago. I was diagnosis with low heart rate. While at hospital my heart stopped for 2 minutes while asleep. My on going issue has been that my pacemaker is activating at different times during and after exercise. It is only supposed to come on at 45 bpm during the day and 40 at night. I should mention while I am 55 I also am very fit and have always had a resting heart rate in the low 50'S. I seems the doctors dont have a way a only controling my resting heart rate. has anyone had a similar situation and was it fixed?

You can have CLS turned off

On your Biotronik, it has rate adaptive technology that can determine what the heart rate should be, based on the Autonomic Nervous System. Biotronik calls this Closed Loop Stimulation (CLS) and activates during exercise, stress, and other times, too, to speed up your heart rate.

With mine, I had them turn this feature off, because it was interfering with the normal rate increases my heart was performing on it's own and in some instances causing tachycardia and heavy palpitations.

I have bradycardia, with instances of the heart stopping, too. But, my Biotronik PM now just keeps my heart from going below 60bpm.

Talk to your Doctor about your concerns, and have it adjusted so you're comfortable with it.

CLS

What exactly do you mean by it's activating at different times during and after exercise? It is speeding your heart rate up inappropriatly?

My first thought was CLS, too. But if you have a night rate and a day rate programmed, CLS is definitely not switched on. CLS does not allow a night rate to be programmed. So, if CLS is on, you cannot be programmed to have 40 at night and 45 at daytime. This is only possible, if either the motion sensor is activated (CLS off) or if no rate response sensor is activated at all.

My guess is that you probably have the motion sensor (also called: accelerometer) switched on, and that this interferes with your own rhythm when you exercise. You can have it switched off or you can have it re-programmed in a way that it responds less aggressively.

Good luck!
