Standard deviation of activation time measured from 96-lead BSM and 12-lead ECG at different pacing modes in CRT patients. Pacing modes: 1, sinus rhythm; 2, atrial pacing; 3, sequential LV pacing (AV delay 120 ms); 4, sequential RV pacing (AV delay 120 ms); 5, sequential biventricular pacing (AV delay 120 ms, VV delay 0 ms); 6, sequential biventricular pacing (AV delay −20 ms intrinsic PQ, VV delay 0 ms); 7, sequential biventricular pacing (AV delay −20 ms intrinsic PQ, VV delay LV −40 ms over RV). BSM, body surface mapping; ECG, electrocardiogram; ICC, intraclass correlation coefficient; SDAT, standard deviation of activation time. *P < 0.001.
