Echocardiography predictors of sustained sinus rhythm after cardioversion of supraventricular arrhythmia in patients with septic shock
Authors' conclusion
The LA_EF and Avti are related to arrhythmia recurrences post-cardioversion suggesting potential guidance to the choice between rhythm and rate control strategies.
Study context
- Population
- Patients in septic shock with onset of supraventricular arrhythmia (SVA), EF_LV ≥35%, on noradrenaline <1.0 μg/kg.min, cardioverted with propafenone or amiodarone
- Participants
- 209 patients
- Outcome
- Echocardiography predictors of sustained sinus rhythm / SVA recurrence after cardioversion
Methodological detailsEchocardiography at arrhythmia onset, 1 h and 4 h post cardioversion
- Echocardiography at arrhythmia onset, 1 h and 4 h post cardioversion
