HR Averaging Method
Method 1
Heart rate is computed by excluding the minimum and maximum
values from the 12 most recent RR intervals and averaging the
residual 10 RR intervals.
Method 2
If each of three consecutive RR intervals is greater than 1200 ms,
then the four most recent RR intervals are averaged to compute
the HR.
Range of Sinus and SV Rhythm
Tachy
Adult: RR interval for 5 consecutive QRS complex ≤ 0.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≤
0.375 s.
Normal
Adult: 0.5 s < RR interval for 5 consecutive QRS complex < 1.5 s.
Pediatric/neonatal: 0.375 s < RR interval for 5 consecutive QRS
complex < 1 s.
Brady
Adult: RR interval for 5 consecutive QRS complex ≥ 1.5 s.
Pediatric/neonatal: RR interval for 5 consecutive QRS complex ≥ 1 s.
Range of Ventricular Rhythm
Ventricular Tachycardia

Ventricular Rhythm
The interval of 5 consecutive ventricular beats ranges from 600
ms to 1000 ms
