Cardiac arrest & resuscitation

Impact of cardiac rhythm dynamics during cardiopulmonary resuscitation on clinical outcomes in patients treated with extracorporeal cardiopulmonary resuscitation (ECPR): a systematic review and meta-analysis

ResuscitationPublished systematic review and meta-analysis

Authors' conclusion

Rhythm dynamics provide valuable prognostic insights for candidates for extracorporeal cardiopulmonary resuscitation. Rhythm decay toward asystole may predict resuscitation failure and poor neurological survival, suggesting that it should prompt a critical re-evaluation of the appropriateness of extracorporeal cardiopulmonary resuscitation.
