心脏性猝死(SCD)定义:
心脏猝死是最常见、最凶险的死因
FIGURE 26–16. Influence of response time on survival from out-of-hospital cardiac arrest. A, The time from onset of cardiac arrest to initial defibrillation attempt is related to 1-month survival, based on data from the Swedish Cardiac Arrest The cumulative survival rate was 5 percent, and the survival rate for victims whose initial rhythm was ventricular tachycardia (VT) or ventricular fibrillation (VF) was percent. The median response time was nearly 13 minutes. Thirty-day survival ranged from a maximum of 48 percent with responses of less than 2 minutes to less than 5 percent for response time greater than 15 minutes. B, The potential for faster response systems, based on the Amsterdam Resuscitation Study, is demonstrated, comparing response times of police vehicles with those of conventional emergency medical systems. At the 50th percentile of response times, polices vehicles provided a nearly 5 minute improvement in arrival time (approximately 6 minutes).337 Preliminary data suggest that improved response times of this type translate to improved
