In an adult, a heart rate of 60-100 beats/min is a normal sinus rhythm (NSR). A heart rate at or above 101 beats/min is called tachycardia, but in young children, this rate would be considered normal. Heart rates belovw 60 beats/min are normal for highly conditioned individuals, but in most adults this is bradycardia I. Calculate the heart rate for the ECGx.0 Diagnosis P-R intervals: Normal P-R intervals are between 0.12 and 0.2 seconds, averaging about 0.16 seconds. P-F intervals...
