precautions and complications

Last reviewed 01/2018

Prior to cardioversion it is important to ensure that:

  • antiarrhythmic drug concentrations e.g. digoxin are within the therapeutic window (some stop drugs several days before cardioversion)
  • the serum potassium is within normal limits

Complications

  • arrhythmias e.g. ventricular tachycardia, ventricular fibrillation

  • thromboembolism:
    • this risk is minimised by formal anticoagulation of patients with long-standing atrial fibrillation or ventricular aneurysm
    • anticoagulation should be for a period of 1 month before the cardioversion and maintained for a further period of 1 month after the cardioversion

  • chest wall burns - this is prevented by the proper use of saline gel pads
