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.

Interpreting the waves and detecting abnormalities: Typically, the heart conducts electricity in a pathway starting in the sinoatrial node (SA), our heart’s “natural pacemaker”, located in the wall of the right atrium. Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia.

It is a physiological adaptation helping athletes perform physical tasks better than non-athletes. Athlete’s bradycardia due to increased parasympathetic tone and decreased sympathetic tone is a well-known observation. The upper limit of physiologic cardiac hypertrophy in highly trained elite athletes. References 1.Prior

Isoprenalin was discontinued, and a temporary transveous pacemaker was implanted. The patient stabilized following pacemaker placement. The physiologic reason for this — is thought to be the result of momentarily increased circulation from mechanical contraction arising from the "sandwiched in" QRS complex.

If there is PR prolongation from one to the next, this supports Mobitz I physiology which rarely benefits from pacing. Conversely, if the PR interval is constant , this supports Mobitz II physiology, which is an indication for pacing. This pattern can be seen in both Mobitz I and Mobitz II physiology. History is often helpful.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
