Suppose a patient develops a myocardial infarction that disables the sinoatrial node. would the heart still pump blood to the aorta and the pulmonary trunk?
If a patient develops a myocardian infraction that disables the sinoartial node, the heart would still pump blood to the aorta and the pulmonary trunk regardless, because the atrioventricular node will still stimulate the ventricular systole.
