November 7, 2026/Cardiovascular System Can You Explain the AV Node Pause? TEAS heart rhythm challenge: What does that brief AV node delay accomplish? Tap to decide now! In the heart, the sinoatrial (SA) node triggers a wave of excitation that causes the atria to contract. When this wave reaches the atrioventricular (AV) node, it pauses for 0.1 seconds before the ventricles contract. Which of the following describes the effect of this pause? <p style="text-align:left;font-family:'Open Sans',arial,helvetica,sans-serif;font-size:16px;color:#000000;margin:0 0 12px;"><input type="radio" name="ans" value="no" /> The ventricles begin contracting before the atria have finished emptying, creating forward pressure.</p><hr /> <p style="text-align:left;font-family:'Open Sans',arial,helvetica,sans-serif;font-size:16px;color:#000000;margin:0 0 12px;"><input type="radio" name="ans" value="no" /> Both chambers contract simultaneously, generating maximum pressure for blood circulation.</p><hr /> <p style="text-align:left;font-family:'Open Sans',arial,helvetica,sans-serif;font-size:16px;color:#000000;margin:0 0 12px;"><input type="radio" name="ans" value="no" /> The atria contract and empty, allowing the ventricles to fill just before they contract.</p><hr /> <p style="text-align:left;font-family:'Open Sans',arial,helvetica,sans-serif;font-size:16px;color:#000000;margin:0 0 12px;"><input type="radio" name="ans" value="no" /> The atria relax and refill with blood before the ventricles begin to contract.</p> Small habit, big results.
