Preliminary results on the prediction of countershock success with fibrillation power
In a study of artifact-free ventricular fibrillation episodes in 54 patients, 28 of whom experienced return of spontaneous circulation (ROSC), the power of different indicators to predict the ROSC was compared. Taking the average of sensitivity, specificity and positive and negative predictive value...

Summary: | In a study of artifact-free ventricular fibrillation episodes in 54 patients, 28 of whom experienced return of spontaneous circulation (ROSC), the power of different indicators to predict the ROSC was compared. Taking the average of sensitivity, specificity and positive and negative predictive value, the dominant frequency reaches 76%, the mean amplitude 72% and fibrillation power 71%. There is little correlation between the three indicators.
Compararam-se vários indicadores com a intenção de avaliar a sua potência na capacidade de prever a recuperação da circulação espontânea num ensaio com episódios de fibrilhação ventricular livre de artefactos em 54 doentes, dos quais 28 recuperaram circulação espontânea. Analisando a sensibilidade, a especificidade e o poder preditivo positivo e negativo, verificou-se que a frequência dominante alcançou 76%, a amplitude média 72% e o poder da fibrilhação 71%. A correlação entre estes três indicadores é baixa. |
