Pacing system analyzer having three sensing and pacing channels

a pacing system and analyzer technology, applied in the field of pacing system analyzers, can solve the problems that the dual-chamber psa capable of sensing electrograms and delivering pacing pulses to two cardiac sites may not be able to accommodate desirable tests, and the programming of an implantable crm device has become an increasingly complicated task for healthcare professionals

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a Divisional of U.S. application Ser. No. 11 / 124,985, filed May 9, 2005, which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This document generally relates to cardiac rhythm management (CRM) systems and particularly, but not by way of limitation, to a pacing system analyzer (PSA) including three or more independently controlled sensing and pacing channels.BACKGROUND

[0003] An implantable pacemaker treats cardiac arrhythmias, heart failure, and / or other cardiovascular disorders by delivering electrical energy to the heart through one or more implantable leads. Before the implantation of the implantable pacemaker, an external (non-implantable) pacing and measuring device known as a pacing system analyzer (PSA) is used to ensure adequate lead placement, maintain basic cardiac functions, and / or evaluate pacing parameters for an initial programming of the implantable pacemaker. In one example of an...
