Changes in electrical dyssynchrony (SDAT) with standard and optimized CRT. Patients without delayed enhancement (DE) had a greater reduction in SDAT compared with those with DE (midwall fibrosis or scar) when standard simultaneous biventricular cardiac resynchronization therapy (CRT) was utilized (−14±10 vs −4±15 ms; P<0.01). Patients with DE had greater reductions in SDAT through 12‐lead ECG optimization of settings compared with patients without DE (−6±10 vs −1±6 ms; P=0.04). SDAT indicates standard deviation of activation times.
