Abstract
A pacing system analyzer (PSA) having three or more individually controllable sensing and pacing channels provides for testing and measurement during an operation for implanting a pacemaker having three or more sensing and pacing channels. The PSA allows control and adjustment of pacing parameters including cross-channel pacing parameters relating activities between any two of the three or more channels, such as atrioventricular and interventricular pacing delays. The PSA is also capable of, among other things, displaying real-time cardiac signals, measuring amplitude and slew rate of cardiac depolarizations, and measuring lead impedance for each of the sensing and pacing channels, as well as measuring time intervals between cardiac depolarizations in two different sensing and pacing channels. In one embodiment, the PSA includes individually controllable atrial, right ventricular (RV), and left ventricular (LV) sensing and pacing channels.
