How long is an sinus pause?

A sinus pause, also known as a sinus arrest, is a temporary cessation of electrical activity in the sinoatrial (SA) node of the heart. It can last for a few seconds to several seconds, typically ranging from 2 to 10 seconds. If the pause is prolonged, it may lead to symptoms like dizziness or fainting. In some cases, longer pauses may require medical evaluation or intervention.
