Figure legends
Figure 1a: registration of monitored tachycardia from Biotronik CRT-D demonstrating signals from all three channels: A: atrium, RV: right ventricle, LV: left ventricles. Cycle length of the tachycardia is 390ms. A-RV delay is 170ms, RV-LV delay is 100ms.
Figure 1b: Intracardiac registration from Biotronik CRT-D demonstrating signals from all three channels: A: atrium, RV: right ventricle, LV: left ventricles as well as far-field ECG (FF) from the right ventricular coil to the device. A-RV delay is 170ms, RV-LV delay is 100ms.
Figure 2: registration of start and end of monitored tachycardia from Biotronik CRT-D demonstrating signals from all three channels: A: atrium, RV: right ventricle, LV: left ventricles. Cycle length of the tachycardia is 390ms. A-RV delay is 220ms, RV-LV delay is 0ms.
Figure 3: registration of start and end of monitored tachycardia from Biotronik CRT-D demonstrating signals from all three channels: A: atrium, RV: right ventricle, LV: left ventricles. Cycle length of the tachycardia is 390ms. A-RV delay is 160ms, RV-LV delay is 100ms.
