End-of-Life Pacemaker Function
Report:
Sinus rhythm 75 – 77/min 1
Third degree AV block 2
Pacemaker rhythm 31/min 2
Probable battery depletion 5
Comment:
Pacemaker interrogation revealed “end-of-life” battery function, set to bipolar VVI mode at 63/min, but obviously firing at half that rate.
Many patients tolerate profound bradycardia surprisingly well. This one was asymptomatic at rest; one measure of his comfort is the normal sinus rate (unless he also suffered from chronotropic incompetence – but this was not a good time to test it).
