AT NID Always looking while rate is in the “Blue Box” Only applies on Detection and not redetection - Rate evaluation is a common criterion in all of our devices. Now we include the atrial rate as well as the ventricular rate. - Most of the SVTs have a characteristic pattern to them. That means that the atrial event generally falls within a specific place relative to the ventricular event. This pattern will help the device identify specific SVTs. - Regularity: As seen in basic ECG interpretation, how regular or irregular the ventricular rate is can help determine the type of arrhythmia present. - AV Dissociation is commonly used in the evaluation of rapid ventricular rhythms. - Rate evaluation is a common criterion in all of our devices.

Define Sign AF Evidence：房颤计数器 AV Dissociation：房室分离 GEM III 以后的产品 Two enhancements have been made to the function of PR Logic in the Gem III AT and the Gem III DR devices. First, the VT-ST boundary is now programmable. In previous devices with PR Logic, this boundary was fixed at 50%. PR Logic uses this parameter to determine the origin of an atrial event when only 1 atrial event occurs in a V-V interval. If the atrial event falls in the antegrade zone, the pattern assumes that antegrade conduction is in progress. If the atrial event falls in the retrograde zone, PR Logic assumes retrograde conduction is in progress. In patients with long AV intervals,
