CRT is a specialized pacemaker therapy used in patients with heart failure and delayed electrical activation (often seen as a widened QRS on ECG). The device stimulates both the right and left sides of the heart to improve coordination and pumping efficiency.
Benefits include:
- Improved heart function
- Reduced hospitalizations
- Better quality of life
CRT may be combined with a defibrillator (CRT-D) in high-risk patients.
