Results for the percentage of pulse triggers resulting in premature complexes in the ECG (average ± standard deviation) for 200 s (yellow), 600 s (red) and fractionated treatment (blue). PCs were significantly less than in the 1st period for the successive periods of the 600 s treatment (†), and the total was significantly less than the total for the fractionated treatments (*)
