KROK 1 2018 – Question 194 · KROK (Medicine) · Pathophysiology
A 48-year-old man is unconscious. He has a history of several syncopal episodes with convulsions. ECG shows deformed QRS complexes unconnected with P waves, atrial contractions are approximately 70/min., ventricular contractions 25-30/min. Name the type of arrhythmia in this case:
- A. Intraventricular block
- B. Intraatrial block
- C. Second-degree atrioventricular block
- D. First-degree atrioventricular block
- E. Complete atrioventricular block
Hint
Compare the atrial rate with the ventricular rate and ask whether the P waves and the QRS complexes still bear any fixed relationship to each other.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
