How to calculate heart rate on EKG?

the countdown method:

by going by the big squares..memorise this sequence:300,150,100,75,50

1500 method:

1500 small swuares represent 1 minute. count the small squares between indentical points on 2 consecutive P waves. then divide 1500 by that number to get the atrial rate. to get the ventricular rate use the same mothod with 2 consecutive R waves.

count the number of big squares between 2 consecutive R waves...then divide 300 by that number.

if the rhythm is irregular, use the 10-time method:

get a 6 second strip (15 big squares= 3 sec), count the number of P waves for atrial rate, or R waves for ventricular rate, ultiply by 10.

The heart rate will be on the paper, goofball.

How to calculate heart rate on EKG?

devide 300 by the number of large sequares between two successive QRS.

this is if the rate is regular
