WebFeb 3, 2024 · How does hyperkalemia cause cardiac symptoms? Potassium and sodium regulate electrical signals in the heart’s muscle, called the myocardium . When the potassium level is too high (or too low), it can interfere with electrical signaling and lead to arrhythmia (irregular heartbeats) or heart palpitations (skipped beats). WebHigh levels of potassium in the blood (called hyperkalemia) is unpredictable and can be life-threatening. It can cause serious heart problems and sudden death.1-3 There are often no warning signs, meaning a person can have high potassium without knowing it.4 If symptoms do occur, they are often nonspecific such as heart palpitations,
