   When this happens, the heart's atrioventricular node or bundle of His can take over as the pacemaker, starting the electrical signal that causes the heart to beat. [ 1 ] [ 5 ] Depending on where the rhythm originates in the AV node, the atria can contract before ventricular contraction due to retrograde conduction , during ventricular ...

   This results in the heart being less able to pump blood effectively and also may cause electrical conduction problems. [3] Specifically, within the bundle branches that conduct impulses through the interventricular septum and into the Purkinje fibers , as these are responsible for the depolarization of contractile cells of both ventricles.

Anyone can be affected by this because overall health does not play a role in the problem. Problems with the electrical pathway of the heart can cause very fast or even deadly arrhythmias.

6. Electrical alternans - Wikipedia

   en.wikipedia.org/wiki/Electrical_alternans

   Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
