the ICD interval plot shown in Figure 1. How does AP initiate during VT? In a typical dual chamber rate-modulating mode (DDDR), AP rate (A-A interval) is determined by the sensor-indicated …

Oct 1, 2015 · A representative interval plot demonstrated a tachycardia within the VT monitor zone (300–450 ms) and a multiple track pattern with alternating short (<100 ms) and 2 …

Dec 1, 2014 · The duration of the device-detected interval that begins with the second event approximates the difference between the spontaneous ventricular cycle length and ICD’s …

Jun 5, 2016 · On the interval plot, open squares denote A-A interval and closed circles denote V-V interval. Horizontal lines denote ventricular tachycardia (VT) and ventricular fibrillation (VF) …

Interval Plots (Tachograms) The interval plot is a graphical presentation of the detected intervals (ms) plotted versus time (sec). The detected intervals preceding arrhythmia detection, during …

Tailored ICD programming can be achieved following evidence from large ICD trials. Pre-defined settings that are saved on the programmer and that can be uploaded at device implantation …

Interval plot (upper panel) and continuous stored electrogram are shown. VT at cycle length 230 ms is diagnosed by AV dissociation and rate as "Fast VT." Change in morphology is clear on ...

We report a comprehensive investigation of distinct Lorenz plot patterns (LPPs) encountered in the context of major cardiac tachyarrhythmias as assessed by 24‐hour Holter monitoring and …

Plot of ventricular intervals versus time from 1 ventricular tachycardia (VT) episode (blue dot, paced; black dot, sensed; and red dot, antitachycardia pacing [ATP]). Detection zones for VT,...

The graph shows a characteristic scatter plot pattern with high interval to interval variability and very short ventricular cycles at the limit of the programmed blanking value; no therapy was …
