Role of ion Regulation in Heartbeat Initiation
Abstract: The heart can beat quite 2 billion times in normal life, but the mechanism by which the guts beats is that the subject of intense research. Since the invention of pacemaker currents in 1978, several studies have shown that rhythmic changes in membrane tension (the "membrane tension clock") underlie the mechanism of automation. It's the depolarizing current activated during hyperpolarization. Therefore, when the guts cells recover, it's activated, the cell …
