How would you decide between conservative management vs. ILR or pacemaker for asymptomatic nocturnal bradycardia/pauses (as an example rates in the 30s, pauses ranging 4-12 seconds) in the absence of bradyarrhythmias during the day and ECG with normal intervals, and not otherwise on medications to slow down HR?

The guidelines are clear in stating that patients with symptomatic bradycardia or higher degree heart block during waking hours would benefit from pacing, but determining symptom-rhythm correlation is not always easy. In sinus node dysfunction, there is no established minimal HR or length of pause t...

I agree with @Dr. First Last' excellent and comprehensive commentary. My practice is consistent with his recommendations for this scenario - i.e., no indication for a pacemaker at this time pending additional work-up but especially a sleep study to r/o OSA.
