* Ask: Is it really working? Do: Choose the same region and state “ You meet a customer in the hall and have 15 seconds to describe how Confirmation+ works. Ask: What would you say?” Do: Advance slide to identify ATPDC. Advance slide again to show Confirmation+ aborted charge during charging process, even for TWOS. * Say: The definition of an arrhythmic event is determined in the existing algorithms by comparing ventricular intervals to a device defined Confirmation interval (CI), or sometimes referred to as Arrhythmic Window. Intervals that are less than (faster than) the Confirmation interval are classified as arrhythmic. 心律失常的确定现有的算法是将心室间期与定义的Confirmation interval (CI)进行比较确定的 间期小于Confirmation interval (CI)被归类为心律失常 In current devices the Confirmation interval is defined as the longest programmed detection interval enabled +60ms. (TDI+60 or FDI+60 if VT detection is off). 在现有的装置中 Confirmation interval (CI)被定义为最长的程控检测间期+60ms。（TDI+ 60或FDI+ 60如果VT检测是off的） Refer to Case #5 for example. TDI + 60ms: 360ms + 60ms = 420ms. Confirmation begins after the Charge End in EnTrust device. Note (building arrows on slide) two intervals TDI + 60ms are confirmed and a shock is delivered. Instructor notes: The rhythm cycle length is a mean (trimmed mean). The trimmed mean is calculated by evaluation the six V-V intervals immediately prior to detection or redetection: the minimum and maximum intervals are dropped and the mean of the remaining four is calculated. * Say: Using the same arrhythmia strip as the prior slide and applying Confirmation+ algorithm, Protecta devices calculates the synchronization intervals based on the actual rhythm of the patient and in addition the device can abort the charge also when ATP During Charging is applied. Confirmation+ uses the same basic algorithm and incorporates a similar 60 ms change to define that the rhythm has slowed. However, the 60ms difference is relative to the intrinsic rate at the point of detection.
