Cardiac resynchronisation therapy (know indications for)
What CRT is
- Pacing both ventricles to correct electrical dyssynchrony in HFrEF
- Hardware: RA lead + RV lead + LV lead via the coronary sinus into a lateral/posterolateral epicardial vein
- CRT-P (pacemaker) vs CRT-D (with defibrillator)
- The only pacing therapy that improves mortality in heart failure
- Corrects the electrical substrate; it is not a substitute for GDMT
