Table 1 Different electrical cardioversion techniques: advantages, disadvantages and efficacy
AdvantagesDisadvantagesEfficacy (%)
External cardioversionSafety Effectiveness Feasibility Outpatient regimen (not in all the centers)General anaesthesia (physical presence of anaesthesiologist) Need of high energies94
Oesophageal cardioversionEfficacy with lower energies Outpatient regimen No general anesthesia First choice in obese and COPD patients Safety in patients with pacemaker or ICD Atrial pacing back upHigh cost of the catheter Contraindicated in patients with oesophageal diseases95
Internal cardioversionVery high effectiveness Use of very low energy No general anaesthesiaNeed of an electrophysiology laboratory Invasive approach Pain perception93
