A member asked:

How can potassium chloride decrease heart rate?

A doctor has provided 1 answer

Potassium: Potassium is a crucial electrolyte for cardiac depolarization. Most of the potassium is intracellular. If the extracellular potassium increases it can slow the depolarization rate, severe hyperkalemia can kill reliably.
