EKG第 73 / 100 题
A monitored patient has a regular rhythm with a rate of 76, a P wave before each QRS, and normal intervals. This rhythm is best described as:
a.Normal sinus rhythm
b.Sinus bradycardia
c.Atrial fibrillation
d.Ventricular tachycardia
解析
Normal sinus rhythm has a regular rate of 60 to 100 beats per minute with a P wave preceding each QRS complex and normal intervals. A rate of 76 with these features is normal. Recognizing normal rhythm helps the technician identify deviations quickly.
