Since a patient has had myocardial infarction, 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:

Answer options

1. Partial atrioventricular
2. Complete atrioventricular
3. Intraventricular
4. Sino-atrial
5. Intra-atrial

Explanation

The frequency of beats in the ventricles is reduced which suggests that impulses are not traveling through the AV-node regularly and that is a sign of complete AV block.
