The Acetylcholibe is released to control the cardiac excitability.
In hyperkalemia, the increased extracellular potassium levels lead to a decrease in the resting membrane potential of cells, making them more excitable. This can result in muscle weakness, cardiac arrhythmias, and potentially cardiac arrest.
Excitability! cha cha!
- rhythmicity : capability of rhythmic self-excitation therefore no need for external control -conductivity: conduction of action potential along specialised muscle cells. -excitability: ability of muscle fibers to get exited . -contractility; ability of cardiac muscle to contract . It also has a long refractory period meaning it cant tetanus
The ability of myocardial cells to respond to an electrical stimulus is known as excitability. This property allows the cardiac muscle cells to generate action potentials in response to electrical impulses, facilitating coordinated heart contractions and maintaining effective blood circulation. Excitability is a crucial aspect of the heart's electrical conduction system.

Neurons are impulse conducting cells that process properties of excitability and conductibility.
