Figure 1 Mid-term hemodynamic changes associated with cardiac resynchronization therapy (CRT). (A) Right ventricular maximum +dP/dt. Statistical significance by one-way repeated measures analysis of variance and paired t tests. (B) Right ventricular fractional area of change (RV FA). (C) Right ventricular end-diastolic area. (D) Grade of tricuspid valve regurgitation. Symbols indicate individual patients according to Table 1. BSA = body surface area; FUP = follow-up on CRT; implant. = implantation.
