If the SA node were eliminated or stopped functioning properly, then it would be up to the AV node to …
Heart rate depends on the rate at which the sinoatrial node produces action potentials. At rest, heart rate is between 60 and 100 beats per minute. This is a result of the activity of two sets of nerves, one acting to slow down action potential production (these are parasympathetic nerves) and the other acting to speed up action potential production (sympathetic nerves). Modulation of heart rate by ANS is carried by two types of channel: Kir and HCN (members of the CNG … Web1. electrodes are placed on skin. 2. electrodes are connected by wires to an instrument that responds to weak electrical signals. 3. tracing is generated on the screen. 4. the distance …
