KROK 1 2014 – Question 128 · KROK (Medicine) · Physiology
Since a patient has had myocardial infarction, his atria and ventricles contract independently from each other with a frequency of 60-70 and 35-40 per minute. Specify the type of heart block in this case:
- A. Intraventricular
- B. Partial atrioventricular
- C. Sino-atrial
- D. Complete atrioventricular
- E. Intra-atrial
Hint
Notice that the atria and ventricles beat at different rates; ask at which level of the conduction system an interruption would let a lower pacemaker take over the ventricles.
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.
