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?

For additional context, work up with TTE and exercise stress testing have all been reassuring and normal.

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...
