How do potassium imbalances affect cardiac function?

Both hyperkalemia and hypokalemia can disrupt the heart's normal electrical rhythm and cause arrhythmias. The heart is unaffected by potassium changes because baroreceptors compensate automatically. Potassium imbalances increase cardiac output by enhancing sympathetic nervous system stimulation. Higher resting blood pressure promotes larger stroke volumes and compensates for potassium changes.
