KROK 1 2013 – Question 128 · KROK (Medicine) · Pathophysiology
Analysis of the ECG revealed the missing of several PQRST cycles. The remaining waves and complexes are not changed. Specify the type of arrhythmia:
- A. Sinoatrial block
- B. Atrioventricular block
- C. Intra-atrial block
- D. Atrial premature beat
- E. Atrial fibrillation
Hint
Entire PQRST cycles drop out while the remaining ones are normal: think about where along the conduction chain the failure must be for atria and ventricles to be silent together.
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.
