How does potassium affect the heart?
Your Heart and Other Muscles If you have a low potassium level, you can get muscle weakness and cramps. Because it’s a muscle, your heart needs potassium. It helps cells send the right electrical signals so that the heart pumps correctly. Having too much potassium in the body can alter the heart’s rhythm.
Does potassium make your heart stop?
Untreated high potassium levels in your blood can cause further heart problems. Hyperkalemia can lead to an irregular heartbeat, known as an arrhythmia. It can even result in a heart attack or death if it’s not diagnosed and treated. Many people with hyperkalemia notice few if any symptoms.
