    • A semiautomatic defibrillator with the capability of delivering a synchronized shock. An advisory algorithm automatically determines whether a synchronized shock should be delivered (e.g., because a shockable tachycardia is detected) and what ECG event should trigger delivery of the shock. And following initiation of a shock by the operator, the defibrillator automatically waits until the required ECG event is detected to deliver the shock. This happens automatically, without the operator being asked to decide between a synchronized and unsynchronized shock, or having to do anything differently to deliver a synchronized shock (e.g., without having to hold a button depressed as necessary to deliver a synchronized shock in manual defibrillators). The unit delivers a shock at the end of a predetermined period if the required ECG event has not been detected, so that a shock always results when the operator initiates one.
    • 半自动除颤器具有提供同步震动的能力。 咨询算法自动确定是否应该传送同步的震动(例如,因为检测到可震荡的心动过速)以及什么ECG事件应该触发冲击的传递。 并且在操作者发起震动之后,除颤器自动等待,直到检测到所需的ECG事件来传递震动。 这种情况会自动发生,不需要操作员在同步和不同步的冲击之间作出决定,或者不得不做任何不同的事情来提供同步的冲击(例如,无需按住必要的按钮来在手动除颤器中传递同步的冲击) 。 如果没有检测到所需的ECG事件,则本机在预定时间结束时会发生冲击,从而当操作员启动时,总​​会导致电击。

    • A defibrillator with an alarm driven by both a heart rate detector and a fibrillation/tachycardia advisory algorithm. The defibrillator is a semiautomatic. By driving the alarm from both sources, the operator is provided with more information; instead of simply being advised of the onset of fibrillation or shockable tachycardia, the operator of a semiautomatic defibrillator is now also advised of the onset of asystole, bradycardia, and nonshockable tachycardia (e.g., superventricular tachycardia). The advisory algorithm can often provide a more timely indication of the onset of an abnormal rhythm than can the conventional heart rate detector, which relies on averaging over multiple heart beats, and thus is slow to detect a change in waveform. And, the advisory algorithm will sometimes detect an abnormal ECG that would have gone undetected by a conventional heart rate alarm. The defibrillator can be combined with an external pacemaker, so that both defibrillation and pacing are available to respond to the conditions detected by the improved alarm. For example, if asystole or bradycardia is detected, the unit can provide pacing stimuli rather than defibrillation stimuli.
    • 具有由心率检测器和颤动/心动过速咨询算法驱动的报警器的除颤器。 除颤器是半自动的。 通过从两个来源驾驶报警器,向操作员提供更多信息; 而不是简单地被告知颤动或可震荡的心动过速的发作,半自动除颤器的操作者现在也被告知心搏停止,心动过缓和非休克性心动过速(例如,室性心动过速)的发作。 咨询算法通常可以提供比正常心率检测器(其依赖于多个心脏跳动的平均)更快速地指示异常节律的发作,因此检测波形变化较慢。 而且,咨询算法有时会检测到常规心律警报不会被检测到的异常心电图。 除颤器可以与外部起搏器组合,使得除颤和起搏都可用于响应由改进的报警器检测的条件。 例如,如果检测到心搏停止或心动过缓,该单元可以提供起搏刺激而不是除颤刺激。
