Table 3. Left- and right ventricular total activation duration during native rhythm and during right- and biventricular pacing.

	TAD LV [ms]	TAD RV [ms]
control native	95±14§‡	89±15*
control RV	125±11‡	122±14*
LBBB native	157±28§†	102±19
LBBB RV	173±25	128±48
LBBB biV	129±16†	108±23

(TAD LV, left ventricular total activation duration; TAD RV, right ventricular total activation duration; native, no stimulation; RV, right ventricular pacing; biV, biventricular pacing; §,*,†,‡ indicate a p-value <0.05).
