Pacemaker assurity mri model2272 installed on June 10th after a cardiac ablation on 85 yr old male.. My problem is trying to understand why the pacemaker, set at 80bpm doesn't keep my heart rate at that pace after I exercise and my heart rate falls to the 50's and stays there. I still have PVC's a after having the ablation. need someone to tell me what is going on? 

Thank you from an old marine



No good answer

There's a lot left out of your description. What sort of ablation? For Afib? Why the pacemaker?

No, a rate of 50 when your PM is set for a minimum of 80 makes no sense, unless you're not counting right. Count manually. Machines are easily confused by any sort of arrhythmia.

A pacemaker can do nothing to fix PVCs,  other than to be set fast enough that they don't have a chance to start. That clearly isn't working.

More information is needed for more than the guess above.

Bradycardia/ pacemaker

Thanks for the reply. Not too versed in medical terms--sorry. I had a cardiac ablation for bradycardia. I am getting the 50 BPM reading from my new BP monitor when I take my blood pressure. My wife uses this and has good results. I use a stationary bicycle and bring my heart rate up to 90 then put on the BP cuff and take several readings watching my pulse rate fall in a 10minute time to 54bpm? I hope I gave you better info. Thanks for your help in this matter.  Dick

Cannot bring up your second reply. .????

pvcs and bp cuff

I have PVCs and my bp cuff pulse rate is inaccurate.  Take it manually, but the PVCs still make it difficult to get an accurate pulse.  Many times my PVCs are every other beat, making the manual rate much slower than the 70 rate my PM is set.  

Write down your questions when you go back to your electrophysiologist.  It also takes time for your heart to adjust to being paced.  


Bradycardia/ pacemaker

I don't know that an "ablation for Bradycardia" is.  Perhaps a sinus node ablation (seems really strange and unnecessarily dangerous)?  If this is it, it can't do anything for PVCs, since they come from the ventricles.

What sort of pacemaker do you have?  Two leads (1- atrium, 1- ventricle)?  The mode would be useful information too but I doubt you have that information.

Your wife's heart is very different than yours, now.  She doesn't have PVCs, for one.  A PVC interrupts the natural cycling of the heart, so either the beat before or the PVC beat is usually much weaker than the other beat.  This confuses any heart rate that uses blood flow to count.  It'll think that one of the beats doesn't exist, so you'll get an unrealistically low rate.

You know you're wired when...

You can hear your heartbeat in your cell phone.
