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.
Arrhythmias happen when the heartâs electrical signal causes it to pump too fast or irregularly. Arrhythmias can prevent the heart from pumping enough blood to your brain and body and cause other problems, such as blood clots. Cardioversion uses medications or low-energy electrical shocks to restore a normal heartbeat. Cardioversion is usually a scheduled procedure. It is an emergency procedure done right away when symptoms are severe. Severe symptoms include dizziness, passing out, chest pain, shortness of breath, and low blood pressure. Cardioversion is only one method of treating cardiac arrhythmias.
