![]() ![]() ![]() After you arrive at the hospital, our care team will take you to a procedure room and ask you to lie down on a treatment table. ![]() You will be asked not to eat or drink anything after midnight on the day of your electrical cardioversion. As a result, your heart’s pacemaker cells take over to restore the normal rhythm of your heart.Įlectrical cardioversion is a scheduled, outpatient procedure. This causes the heart cells to release all of their chaotic, disorganized energy at once. But instead of turning off your heart’s power source, it delivers a low current of electrical energy to the heart. For AFib patients, the heartbeat is often chaotic and fast.Įlectrical cardioversion is a little bit like “rebooting” your laptop. When a person with AFib or atrial flutter experiences an episode, the heart may beat as many as 300 times per minute or more in the upper heart chambers and 100-200 times per minute in the lower heart chambers. Arrhythmia episodes can last for a few minutes, hours, or even a few days.Ī normal resting heartbeat is between 60 and 100 beats per minute. This can make your heart rate fast and irregular. As a result, the heart’s upper chambers beat too quickly. A heart arrhythmia develops when the electrical system of your heart is not working correctly or is replaced by short circuits. The system depends on specialized pacemaker cells in the upper atria to start each heartbeat. When this system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. Your heart’s electrical system is the power source that makes your heartbeat. Cardiologists at University of Utah Health use this therapy for people with heart rhythm disorders ( arrhythmias), including atrial flutter and atrial fibrillation (AFib). ![]()
