WebNov 16, 2024 · The sinus node is a group of cells in the heart that generates these impulses, causing the heart chambers to contract and relax to move blood through the body. A normal heartbeat is referred to as normal sinus rhythm (NSR). An abnormally slow heartbeat is called bradycardia, while an abnormally fast heartbeat is called tachycardia. WebYou will also have seen a small negative wave following the large R wave. This is known as an S wave and represents depolarisation in the Purkinje fibres. The S wave travels in the opposite direction to the large R wave because, as can be seen on the earlier picture, the Purkinje fibres spread throughout the ventricles from top to bottom and then back up … hwg lu bmc modulhandbuch https://prosper-local.com
