The sinus node sends electrical signals that typically start each heartbeat. These electrical signals move across the atria, causing the heart muscles to squeeze (contract) and pump blood into the ventricles.

WebA slow beat is defined as a ventricular paced or ventricular sensed event that is at least 150 ms slower than the AAI (R) pacing rate. The 150 ms value is used to allow for normal variations between cardiac cycles. Slow ventricular beats are any of the following: V paced event. V sensed event &gt; AAI lower rate limit + 150 ms.
