Role of transthoracic impedance and current in synchronized electricalcardioversion

Synchronized cardioversion is a medical treatment that applied an electrical pulse to restore a normal heart rhythm is patients with an abnormally fast heart rate or cardiac arrhythmia. A successful cardioversion is dependent on the amount of electrical current that reaches the heart, which depends on the strength of the electrical pulse and the transthoracic impedance (electrical impedance of the body). If a cardioversion is not successful, additional attempts

are often made; however, repeated delivery of a large electrical pulse is not desired. Increasing the strength of the electrical pulse is also not ideal as it increases the chances of complications. This research will investigate the role of transthoracic impedance on cardioversion, which will also include the effect of different paddle placement. Outcomes of this research will help improve the efficacy of cardioversion, increase the success of treatments, while minimizing the strength of the electrical pulse.
