Key result
Pacemaker-induced cardiomyopathy occurs in 10-20% of patients following right ventricular pacing and can be effectively managed or prevented by upgrading to cardiac resynchronization therapy or utilizing His bundle pacing.
Why the study?
Pacemaker-induced cardiomyopathy (PICM) reduces LV function and can trigger clinical heart failure, prompting interest in identifying at-risk patients and establishing effective management and prevention strategies.
This review summarizes current literature on the identification, management, and prevention (e.g., via His bundle pacing) of pacemaker-induced cardiomyopathy.
Pacemaker Induced Cardiomyopathy (PICM) is commonly defined as a reduction in left ventricular (LV) function in the setting of right ventricular (RV) pacing. This condition may be associated with the onset of clinical heart failure in those affected. Recent studies have focused on potential methods of identifying patients at risk of this condition, in addition to hypothesizing the most efficacious ways to manage these patients. Newer pacing options, such as His bundle pacing, may avoid the onset of PICM entirely.

Callan Gavaghan (2021) conducted a review in Pacemaker Induced Cardiomyopathy (PICM). Pacemaker-induced cardiomyopathy occurs in 10-20% of patients following right ventricular pacing and can be effectively managed or prevented by upgrading to cardiac resynchronization therapy or utilizing His bundle pacing.
