Electrocardiograms (EKGs/ECGs): Determining The Heart Rate
Webb31 jan. 2024 · One method is to divide 1500 by the number of small squares between two R waves. For example, the rate between beats 1 and 2 in the above tracing is 1500/22, which equals 68 beats/min. Alternatively, one can divide 300 by the number of large squares, which is 300/4.4 (68 beats/min). Another method, which gives a rough approximation, is … WebbEach large block contains 25 squares.
