CRT-P
Also written as: CRT-P — Cardiac Resynchronization Therapy Pacemaker
A specialized pacemaker device that coordinates ventricular contractions in heart failure patients without defibrillation capability.
Full Definition
Cardiac Resynchronization Therapy Pacemaker (CRT-P) is a specialized three-lead pacing device designed to improve cardiac function in patients with heart failure and ventricular dyssynchrony. Unlike CRT-D devices, CRT-P does not include defibrillation capability, making it appropriate for patients who do not meet criteria for implantable cardioverter-defibrillator therapy. In geriatric cardiology, CRT-P may be preferred over CRT-D in elderly patients with limited life expectancy or those who prefer to avoid defibrillation shocks.
Usage
Usage note: Always distinguish from CRT-D; specify rationale for choosing CRT-P over CRT-D when applicable.
