No QRS is detected for 4 consecutive seconds
V-Fib/V-Tach
4 consecutive seconds' fibrillation wave occurs; Or 5 consecutive
ventricular beats, and ventricular HR ≥ 100 bpm.

R on T
A type of single PVC under the condition that HR < 100，R-R interval is
less than 1/3 the average interval, followed by a compensating pause of
1.25X the average R-R interval (the next R wave advances onto the
previous T wave).
PVC
Single PVC detected in normal heartbeats, and the number of consecutive
single PVC ≥4 within 30 s.
Tachy
Adult: RR interval for 5 consecutive QRS complex ≤ 0.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≤ 0.375 s.
Brady
Adult: RR interval for 5 consecutive QRS complex ≥ 1.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≥ 1 s.
Missed Beat
Basic:
If HR < 120 bpm, no beats are detected for 1.75 times average RR
interval; or if HR
≥
120 bpm, no beats are detected for one second; or no
valid QRS wave is detected within 3 s or longer.
Advanced:
If HR < 120 bpm, no beats are detected for 1.75 times average RR
interval; or if HR ≥ 120 bpm, no beats are detected for one second.
