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

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

Her excitability was contagious, and soon everyone in the room was excited.
