Question

Quizplus · Accepted Answer

Second Degree Heart Block is caused by intermittent AV conduction, meaning that there are occasional pauses or delays in the electrical signals traveling from the atria to the ventricles. This can result in skipped or irregular heartbeats. SA node failure, resistance in ventricles, and loss of failsafe mechanism are not typically related to Second Degree Heart Block.
