More Information
Summary:Methods and devices for combining multiple signals from multiple sensing vectors for use in wearable or implantable cardiac devices. Signals from multiple vectors may be combined using weighting factors and/or by conversion to different coordinate systems than the original inputs, which may or may not be normalized to patient anatomy. Signals from multiple sensing vectors may be combined prior toor after several analytical steps or processes including before or after filtering, and before or after cardiac cycle detection. Cardiac cycle detection information may be combined across multiple sensing vectors before or after analysis of individual vectors for noise or overdetection. Cardiac cycle detection information may also be combined across multiple sensing vectors to identify noise and/or overdetection. 用于组合来自多个感测矢量的多个信号以用于可穿戴或可植入心脏设备的方法和设备。来自多个矢量的信号可以使用加权因子和/或通过转换到与原始输入不同的坐标系统来组合，其可以或可以不针对患者解剖结构进行归化。来自多个感测矢量的信号可以在几个分析步骤或过程之前或之后(包括在滤波之前或之后以及在心脏周期检测之前或之后)进行组合。心脏周期检测信息可以在分析单独矢量之前或之后跨多个感测矢量进行组合以用于噪声或过度检测。心脏周期检测
