EKG Question #5
The nurse will analyze the following electocardiogram strip:
What is the calculated heart rate of the strip above?
- 60-70 beats per minute
- 70-80 beats per minute
- 30-40 beats per minute
- 50-60 beats per minute
The ECG above reveals a heart rate of 34. There are three R-R segments within a 6-second strip. To be more precise, there are 44 small boxes between any R-R, which is
1500/44 = 34 beats per minute. This heart rate represents a serious bradycardia.
