- 34. Rhythm (reg/irregular): Regular Rate: 90 PR Interval QRS: QT: Rhythm Interpretation: ****NO PULSE noted on palpitation**** 35. Rhythm (reg/irregular): Pegular Rate: 140 PR Interval QRS: QT: Rhythm Interpretation:The electrocardiograph records the tracing at standard speed of 25 mm/second. This allows a person to deter- mine the heart rate and the duration of the intervals. Each small box on the ECG tracing measures 0.04s, and each large box measures 0.20s. Five large boxes together measure 1 second. Determining the duration of most intervals is simple by counting the small or large boxes and add the seconds together. To calculate the heart rate, count the number of large boxes, and divide 300 by this number. For example, if you count 4.2 boxes, 300/4.2=71 beats per minute. The normal values or the periods are given in Table 6-3 provided below. Period Normal Value Table 6-3 Normal Values for ECG Periods Heart rate 60-100 beats per minute R-R interval 0.60-1.0s P-R interval 0.12-0.20s Q-T interval 0.42-0.44s QRS complex duration Less than or equal to 0.12s1. is the rhythm regular or irregular 2. determine the heart rate 3. do you have p waves before every QRS 4.
