Dynamic changes in intracardiac resistance as a predictive marker during internal cardioversion of atrial fibrillation |
Abstract | ||
---|---|---|
Intracardiac resistance (ICR) is an important determinant of treatment success during internal cardioversion of atrial fibrillation (AF). However, there is limited data on dynamic changes in ICR as a predictor of cardioversion outcome. In this retrospective study, thirty patients with persistent AF were randomised to treatment with a biphasic or monophasic energy step-up cardioversion protocol (50V-to-300V in 50V steps). ICR was computed for each patient and a student t-test used to investigate the significance of dynamic changes in ICR between successive shocks delivered. For both biphasic and monophasic waveforms, all patients who cardioverted exhibited a significant reduction in ICR between the first and third shock (p<;0.01 and p<;0.003, respectively). Yet, critically, a significant reduction in ICR was absent for all patients who failed to cardiovert (p>0.05 for both waveforms). A statistically significant decrease in ICR during the first three shocks was identified as a predictive marker for successful cardioversion outcome. |
