Abstract

The potential impact of efforts to improve the chain of survival for out-of-hospital sudden cardiac arrest (SCA) is unclear in part because estimates of the incidence of treatable cases of SCA are uncertain. The aim of the investigation was to determine a representative national incidence of emergency medical services (EMS)-treated all-rhythm and ventricular fibrillation (VF) SCA as well as survival. We used Medline to identify peer-reviewed articles published between 1 January 1980 and 31 March 2003 that reported a US community's EMS SCA experience. Inclusion criteria required the study to include at least 25 cases, report the total number of all-rhythm and/or ventricular fibrillation arrests, and provide information about population size and study duration. Incidence was computed by dividing the total number of SCA events by the product of the community's population and the study duration. Reports from 35 communities met the inclusion criteria. A total of 35,801 all-rhythm EMS-treated cardiac arrests occurred during 62.11 million person-years of observation resulting in an overall incidence of 54.99 per 100,000 person-years. The incidence of ventricular fibrillation-rhythm SCA was 21.32 per 100,000 person-years. Sensitivity a...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
