Conditions
Brief summary
All patients on the waiting list for elective DC cardiovesion will be offered the chance to participate In this study. If they agree, we will record the results of the different laboratory and imaging tests that they had prior to presenting to the preadmission clinic, as well as each individual medical background. Each patient will have 4 extra blood tests to measure the hormones produced by the heart and other parts of the body in response to their heart condition. The first 2 tests will be on the day they present for the electric shock treatment (DC cardiovesion). The 3rd when having the 6 weeks routine follow up, and the last one will be when having the 6 months follow up. Each patient will, also, have an additional ultrasound examination of the heart 4-8 months following having the DC cardioversion. Each patient will be followed for a minimum of 1 year (the 2 other follow ups at 6&12 months post DC cardioversion). During this time we will monitor the heart rhythm, the rate of possible complications with this condition and analyse the data trying to identify the patients who may benefit from this treatment.
Interventions
Participants will also be randomly assigned to biphasic defibrillation as a single cardioversion procedure which takes about 3-5 minutes.
