Methods Consecutive patients with bradycardia indicated for pacing from 2016 to 2022 were prospectively followed for the clinical endpoints of heart failure (HF)-hospitalizations and all-cause mortality at 2 years. CSP should be preferred over VSP or RVP during pacing for bradycardia.

Introduction: Leadless pacemakers (LP) are increasingly utilized in pts with bradycardia and may be associated with better outcomes compared to right ventricular pacing (RVP). Conduction system pacing (CSP) with HBP or LBBAP have been associated with reduction in death or heart failure hospitalization (HFH).

The ECG shows an example of a patient with bradycardia/tachycardia syndrome. Patients with bradycardia/tachycardia syndrome usually require a heart pacemaker to prevent the heart rate from becoming too slow.

My thoughts were the following: ECGs #1 and #2 showed a completely unreliable sinus pacemaker, with presumed high-grade 2nd-degree AV block — and frequent resultant pauses of over 2 seconds ( that would have been even longer had it not been for intermittent relief from the atrial escape focus ).

I tell the residents: "The pacemaker is just common sense: if there is no beat, it provides one; if there is one, it keeps itself from pacing." This is similar to Ken Grauer's comment at the bottom: "What would I do if I were a pacemaker?" This made me realize that pacemaker function is not as well understood as I thought.
