Figure 6. Effect of acute (1-minute) quadrigeminal PVC challenge (200 ms coupling) on NA and BP at baseline, PVC-CM and recovery.

Figure 6.

(A) Acute SNA increase within seconds after PVC onset, followed by a slower rise in systolic BP. (B) Mean systolic BP and integrated NA over 5-sec period, before and after PVC onset. (C) Comparison of NA and mean systolic BP in 30-sec segments before vs after PVC onset.
