WebbNote that the degree of block in the atrioventricular node may vary from one cardiac cycle to the next and this yields an irregular ventricular rate. As seen in Figure 3 , however, it is usually simple to diagnose atrial flutter with irregular ventricular rate because the flutter waves become clear at longer RR intervals.
WebbHeart rate is a measure of ventricular rather than atrial activity. Impulses from the atria are conducted to the ventricles through the atrio-ventricular node (AV node).
