Which of the following can be used to calculate hea rate from an ECG?
For calculating hea rate: HR-300/ Number of large squares(0.20 secs) in one R-R interval HR-1500/no of small squares (0.04 secs) in one R-R interval
Number of large squares in one R-R interval/300
300/ (Number of large squares in one Q-T interval)
300/ (Number of large squares in one R-R interval)
(Number of large squares in one Q-T interval) / 300
