Article Synopsis
- Cardiac physiologic pacing (CPP) includes techniques like cardiac resynchronization therapy (CRT) and conduction system pacing (CSP) aimed at reducing heart failure in patients with issues in heart rhythm.
- The clinical guideline outlines recommendations for when to use CRT in heart failure patients, how to select suitable candidates, and key steps for pre-procedure preparation and ongoing care.
- It also highlights areas where more research is needed to improve understanding and application of these pacing therapies, especially for children.
Cardiac physiologic pacing (CPP), encompassing cardiac resynchronization therapy (CRT) and conduction system pacing (CSP), has emerged as a pacing therapy strategy that may mitigate or prevent the development of heart failure (HF) in patients with ventricular dyssynchrony or pacing-induced cardiomyopathy. This clinical practice guideline is intended to provide guidance on indications for CRT for HF therapy and CPP in patients with pacemaker indications or HF, patient selection, pre-procedure evaluation and preparation, implant procedure management, follow-up evaluation and optimization of CPP response, and use in pediatric populations. Gaps in knowledge, pointing to new directions for future research, are also identified.

En este estudio se busca obtener un dato preciso del porcentaje de volumen expulsado en sentido anterógrado en pacientes con insuficiencia mitral.
MÉtodos: Se aplica una fórmula ecocardiográfica de "corrección" de la fracción de expulsión del ventrículo izquierdo (FEVI) en 114 pacientes con insuficiencia mitral, con base en la medición de la fracción regurgitante.
