Quizplus · Accepted Answer

Sinus arrest refers to a pause in the normal electrical activity of the heart's sinoatrial (SA) node, which is responsible for initiating each heartbeat. This pause can occur at any heart rate, not just at lower rates, and can cause symptoms such as dizziness, fainting, or cardiac arrest if it lasts for a prolonged period.
