What Causes an Arrhythmia? An arrhythmia can occur if the electrical signals that control the heartbeat are delayed or blocked. This can happen if the special nerve cells that produce electrical signals don't work properly. It also can happen if the electrical signals don't travel normally through the heart.
You could have an arrhythmia even if your heart is healthy. Or it could happen because you have: 1  Heart disease. 2  The wrong balance of electrolytes (such as sodium or potassium) in your blood. 3  Changes in your heart muscle. 4  Injury from a heart attack. 5  Healing process after heart surgery.
