WebThese impulses conduct throughout the heart, causing the movement of the heart's muscle. Certain diseases can produce irregularities in this activity; if it is sufficiently interrupted, it … WebFirst-degree heart block: The electrical impulse still reaches the ventricles, but moves more slowly than normal through the AV node. The impulses are delayed. This is the mildest type of heart block. ... Third-degree heart block: The electrical signal from the atria to the ventricles is completely blocked. To make up for this, the ventricle ...
WebNov 14, 2024 · Normally, electrical impulses travel down the right and left bundle branches of the ventricles at the same speed. This allows both ventricles to contract at the same time. But when there’s a “block” in … http://www.secondscount.org/tests/test-detail-2/electrocardiogram
