WebLeft atrial flutters are not as common as peri-tricuspidian circuits. Their systematic study is much more recent and had greatly benefited from the use of 3 D mapping systems. Reentry has been demonstrated as being the mechanism but the circuits are not stereotypical like in the right atrium. Multiple macroreentrant circuits with one or more … WebAdvanced - Cardiac Conduction. Cardiac conduction in the adult heart begins in the sinoatrial (SA) node which is located at the junction between the SVC and the right atrium. The impulses generated here spread through the atria, initiating contraction. The impulses travel to the atrioventricular (AV) node which acts to slow the transmission of ...
