EKG第 75 / 100 题
A monitored patient's rhythm is regular with a normal-appearing complex and P waves, at a rate of 120 beats per minute. This is best described as:
a.Sinus bradycardia
b.Normal sinus rhythm
c.Sinus tachycardia
d.Asystole
解析
Sinus tachycardia is a regular sinus rhythm with a rate above 100 beats per minute, so 120 with normal P waves fits. It can result from fever, pain, anxiety, dehydration, or exertion. The underlying cause should be identified and reported as appropriate.
