Study Overview
Brief Summary
The aim of this study is to identify the one electrode position out of two most commonly used for external electrical cardioversion of typical atrial flutter, which needs less delivered energy and less needed number of shocks for successful cardioversion.
Detailed Description
Typical atrial flutter is the second-most prevalent atrial tachyarrhythmia. No guidelines for treatment exist and few studies investigate treatment of atrial flutter. Mostly, guidelines for atrial fibrillation are followed for treatment of atrial flutter. Atrial flutter has a different pathomechanism as atrial fibrillation, therefore special guidelines for treatment are needed. Among drug treatment and ablation procedures, external electrical cardioversion is commonly used, especially for treatment of acute symptomatic patients. This study may help to further define safe and successful procedures for electrical cardioversion of atrial flutter.

Arms & Interventions
AP Position
Cardioversion with antero-posterior electrode position
Intervention: external electrical cardioversion (with antero-posterior electrode position) (Procedure)
AL Position
Cardioversion with antero-lateral electrode position
Intervention: external electrical cardioversion (with antero-lateral electrode position) (Procedure)
Outcomes
Primary Outcomes
Number of Successfully Cardioverted Participants for Each Electrode Position
Time Frame: 30 seconds after cardioversion
After restoration of normal sinus rhythm for 30 seconds and longer by electrical countershock a cardioversion is counted as successful.
Secondary Outcomes
- Number of Participants Succesfully Cardioverted With First Shock in Each Electrode Position(30 seconds after cardioversion)
- Mean Number of Cardioversion Shocks(30 seconds after cardioversion)
- Mean Energy Requirement for Successful Cardioversion(30 seconds after cardioversion)
