How do you fix the electrical system of the heart?

Typically, surgeons defibrillate the heart—send it a controlled electrical shock—to reset the electrical system, and then implant a pacemaker or defibrillator to maintain it.

How do you treat electrical problems in the heart?

With electrical cardioversion, a high-energy shock is sent to the heart to reset a normal rhythm. It is different from chemical cardioversion, in which medicines are used to try to restore a normal rhythm. Normally, a special group of cells begin the electrical signal to start your heartbeat.

What causes an electrical problem in the heart?

What causes heart arrhythmias? Our heartbeats are controlled by electrical signals. Arrhythmia can happen if those electrical signals are delayed or blocked because of problems with heart muscle cells or blockages in the heart’s electrical system, or when extra circuits or spots in the heart give off extra beats.

What are the side effects of having your heart shocked?


  • Dislodged blood clots. Some people who have irregular heartbeats have blood clots in their hearts. …
  • Abnormal heart rhythm. In rare cases, some people who have cardioversion develop other heart rhythm problems during or after the procedure. …

How do you check an electrical heart?

An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.
