Figure 4 Mean (±SEM) arterial pressures and SNA levels for all 10 patients during pacing rates of 60 and 90 beats/min after complete AV node block was achieved by RF ablation. The data for pacing at 60 beats/min were collected immediately before pacing at 90 beats/min. Asterisks indicate significant differences between pacing rates (p < 0.05).
