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:

  1. A. Intraventricular block
  2. B. Intraatrial block
  3. C. Second-degree atrioventricular block
  4. D. First-degree atrioventricular block
  5. 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.
