Heart surgery may cause a decrease in the transmission of impulses in the Purkyne tissue to the right side of the heart.
What is a possible effect of this decrease?
1 )
Impulses would be delayed by the atrioventricular node.
The muscle of the right ventricle would contract slightly more slowly than the muscle of the left ventricle.
3 )
The muscle of the right atrium would not contract as fully as the muscle of the left atrium.
4 )
The sinoatrial node would transmit fewer impulses.
