Which statement concerning the AV nodal delay is correct?

Question

Quizplus · Accepted Answer

The AV nodal delay ensures that the atria have enough time to contract and empty their contents into the ventricles before the ventricles contract during ventricular systole. This allows for efficient blood flow and prevents regurgitation. Choice B is incorrect as the AV nodal delay ensures atria contract before ventricles. Choice C is incorrect as the AV nodal delay has nothing to do with tetanic contraction. Choice D is incorrect as parasympathetic stimulation actually prolongs the AV nodal delay.
