BACKGROUND: The purpose of this study was to determine the causes and the prognosis of consecutive @entity1 resuscitated from @entity1167 occurring in a general hospital. We assessed 28 females and 94 males (aged 13-82 years) who were resuscitated from @entity1167 not attributable to acute @entity583 . @entity2224 ( @entity2224 ) was documented in 97. Non-cardiac causes were excluded. Non-invasive studies (24 h Holter monitoring, 2D echocardiogram, signal-averaged ECG, exercise testing, magnetic resonance imaging) and invasive studies (right and left ventricular angiography, coronary angiography and complete electrophysiologic study (EPS) were performed. RESULTS: An underlying @entity299 was found in 107 @entity1 (88%). @entity1 were followed for a period ranging from 6 months to 10 years (mean 4+/-5 years). Several causes for @entity1167 were identified and treated specifically. The prognosis was variable. Among surviving @entity1 the following causes of @entity1167 were found: @entity3153 (n=2), rapid supraventricular @entity591 (n=6), acquired or @entity1162 (n=7), complete @entity713 (n=3), proarrhythmic effect of an antiarrhythmic drug (n=5), @entity951 (normal coronary arteries) (n=5). Among ten @entity1 with @entity2224 related to @entity299 two died suddenly. @entity1165 ( @entity1165 ) or @entity2224 was the main cause leading to resuscitation after @entity1167 (n=64). The risk of recurrence of arrest is confirmed in the present study particularly in @entity1 in whom @entity1165 / @entity2224 could not be suppressed by antiarrhythmic drug therapy (n=45) and in those where an @entity1479 was not implanted (18 @entity204 (nine sudden @entity204 ( @entity5099 's)). The cause of @entity1167 was not elucidated in 20 @entity1 (16%). The prognosis of these @entity1 differed according to the documentation of @entity2224 at the time of @entity1167 : of those with documented @entity2224 (n=12), six @entity1 died suddenly (one with an @entity1479 ); of those without documented @entity2224 (n=8), all are alive. CONCLUSION: To determine the precise cause of @entity1167 was the first problem; the diagnosis of @entity1167 clearly was erroneous in 8 of 122 @entity1 (6.5%). In other @entity1 , a @entity1165 was identified as the cause for @entity1167 in half of the population; the indication for an @entity1479 is evident in this group. In 31% of @entity1 with proven @entity1167 , another @entity943 requiring specific treatment was identified and @entity1479 implantation was avoided; these @entity1 had a survival of 92% at 3 years. In @entity1 without an identified cause of @entity1167 and negative EPS, the prognosis was unfavorable only in those with documented @entity2224 .
