Lewis Dysrhythmias (Ch. 36)with complete solutions 2023When computing a heart rate from the ECG tracing, the nurse counts 15 of the small blocks between the R waves of a patient whose rhythm is regular. From these data, the nurse calculates the patient's heart rate to be a) 60 bpm b) 75 bpm c) 100 bpm d) 150 bpm c) 100 bpm (Since each small block on the ECG paper represents 0.04 seconds, 1500 of these blocks represents 1 minute.
