Introduction: Right ventricular (RV) pacing can impair left ventricular function and cause heart failure, known as pacing-induced cardiomyopathy (PICM). Upgrade to cardiac resynchronization (CRT) is its usual treatment; recently left bundle branch area pacing (LBBAP) has emerged as a potential alternative. Deep septal pacing (DSP), a simplified alternative to LBBAP, is still able to achieve narrower paced QRS than during conventional RV pacing.

- The study investigates whether cardiac resynchronization therapy with a defibrillator (CRTD) is better than therapy with a pacemaker (CRTP) for patients with non-ischemic cardiomyopathy (NICM) and low risk of arrhythmias.
- It analyzes data from 167 NICM patients, looking for predictors of heart function improvement (echocardiographic response) and serious heart rhythm issues (arrhythmias) over a median follow-up of 63 months.
- Findings reveal that patients without late gadolinium enhancement (LGE) show a much higher response rate to CRT (81% vs. 53%) and no arrhythmic events, suggesting they are ideal candidates for CRTP rather than

Introduction And Objectives: We describe the results for Spain of the Second European Cardiac Resynchronization Therapy Survey (CRT-Survey II) and compare them with those of the other participating countries.
Methods: We included patients undergoing CRT device implantation between October 2015 and December 2016 in 36 participating Spanish centers. We registered the patients' baseline characteristics, implant procedure data, and short-term follow-up information until hospital discharge.
