Vitatron G20 SR, at the completion of the 30 minute Implant Detection period, Rate Profile Optimization is enabled; the appropriate pacing and sensing polarities are naturally selected by the device; Ventricular Output Management is enabled and Amplitude and Pulse Width become adaptive. Cardiac Dashboard II is a highlights significant events, AT/AF and pacing summary, threshold and impedance trends. AT/AF compass trends data compiles up to 6 months of daily clinical information in an easy to interpret graphic format and access to AT/AF diagnostics. P wave/R wave amplitudes and approach to A and V sensitivity trends. It provide heart rate histograms reports. Number of hours/day in atrial arrhythmia, percentage of time. Atrial and ventricular lead impedance trends. Pacing summary and approach to rate histogram. t has ventricular pacing threshold trends.
