Low rate set at 70 HR has dropped lower
Looking for some advice please. My Husband has a Medtronic dual lead pacemaker inserted in January for Heart block. He also had an Ablation for Afib in March. We are seeing the EP tomorrow as we feel we need some questions answered, ie breathlessness, postural hypotension which seem to have worsened since these procedures. The last few days we have been monitoring BP/HR/symptoms more often in order to discuss with the EP. Today I believe John is having an episode of Afib, his heart rate is jumping around however my question is with his lower limit set to 70 his heart rate has dropped as low as 39 for a few beats and then climbs back up to high 60’s low 70’s. While John was napping I watched the finger oxygen monitor for probably 10 mins as an example over approx 12 beats his rate was:
Is this how a pacemaker should work or should it respond more quickly.
As this is all relatively new to us any suggestions or insights would be helpful as we would like to be able to ask informed questions at the EP’s appointment tomorrow. Thank you.
