Reasons for Procedure
- Atrial fibrillation —very rapid, irregular quivering in the atrium; ventricles pump irregularly
- Atrial flutter —rapid but regular contractions in the atrium, when the ventricular heart rate is not too fast
- Inability to stop the abnormal rhythm
- Abnormal rhythm is resumed after a normal rhythm was established
- Development of a more dangerous dysrhythmia
- Damage to the heart muscle
- Blood clots introduced into your circulation, leading to such complications as stroke or damage to your organs
- Burning or irritation to the skin of the chest where the paddles or electrodes are applied
