Cardiac resynchronization therapy (CRT) is a proven treatment for selected patients with heart failure-induced conduction disturbances and ventricular dyssynchrony. When used in combination with stable, optimal medical therapy, CRT is designed to reduce symptoms and improve cardiac function by restoring the mechanical sequence of ventricular activation and contraction.
A high-energy, wireless device with features that help to ensure CRT.
Key features include:
For CRT-D devices, certain programming and device operations may not provide cardiac resynchronization. Changes in a patient's disease and/or medications may alter the efficacy of a device's programmed parameters.
