Question

A 50-year-old man has been having fainting "spells" for about 2 weeks. During the episodes, his ECG shows a ventricular rate of 25 beats/min and 100 P waves per minute. After about 30 seconds of fainting, a normal sinus rhythm recurs. What is his likely diagnosis?A) Atrial flutter.B) First-degree A-V block.C) Second-degree A-V block.D) Third-degree A-V block.E) Stokes-Adams syndrome

Answer 1

He must have Stokes-Adams syndrome.

Answer: Option E

Step-by-step explanation:

Continuous fainting spells that is diagnosed as the Stokes-Adams syndrome. It is caused because of the heart rhythm beating very slow or absent in pulse rate mainly due to the blockage in the heart. In ECG it shows a ventricular rate of 25beats/min as the heartbeat passing from the upper to the lower chamber is interrupted.

This interruption is caused due to the blockage in the heart. This causes low blood flow towards the brain and hence he becomes unconscious now and then.
