Table 1 Detailed judgment rules of 5 types of ECG rhythms.

From: Mobile GPU-based implementation of automatic analysis method for long-term ECG

Type of rhythms Rules
NB QRS complex width < 120 ms
  0.75× average RR interval < current RR interval
  Current RR interval < 1.2× average RR interval
APB QRS complex width < 120 ms
  Current RR interval < 0.75× current average RR interval
  Current RR interval + next RR interval < 2× current average RR interval
VPB QRS complex width > 120 ms
  Current RR interval < 0.75× current average RR interval
  Current RR interval + next RR interval ≥ 2× current average RR interval
BG Alternating appearance of VPB and NB
TG Alternating appearance of 2 NBs and 1 VPB
