A26-year-old client is returning for diagnostic follow-up. her holter monitor strip reveals a heart rate with normal conduction but with a rate consistently above 105 beats/minutes. what type of dysrhythmia would you expect the cardiologist to diagnose?

a) sinus tachycardia
b) supraventricular bradycardia
c) sinus bradycardia
d) supraventricular tachycardia

The correct option is: A. Sinus tachycardia    

Explanation:

Sinus tachycardia is a medical condition characterized by heartbeat greater than 100 beats/min. In this medical condition, the electrical impulses emerging from the sinoatrial node of the right atrium of heart increases, which leads to elevation of the sinus cardiac rhythm.

Sinus tachycardia is a generally a normal response to physical stress but it can also suggest a health problem.

Therefore, cardiologist will most likely diagnose Sinus tachycardia.
