Multi-Channel Pacing System Analyzer for Tri-Chamber Pacemaker Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pacing system analyzers (PSAs) are inadequate for testing and programming of tri-chamber pacemakers, as they often lack the capability to accommodate multiple sensing and pacing sites and parameters, making it difficult to ensure proper lead placement and set suitable pacing parameters for advanced cardiac rhythm management systems.
Innovation Solution
A PSA with three or more independently controlled sensing and pacing channels, including atrial, right ventricular, and left ventricular channels, that allows for real-time signal display, measurement of lead impedance, and adjustment of pacing parameters such as interventricular delays, enabling comprehensive testing and programming of multi-chamber pacemakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-chamber PSA is used, then basic pacing functions can be tested, but it cannot accommodate tri-chamber pacemaker testing requirements
Solution Approach 1:
The PSA is designed with three independently controllable sensing and pacing channels that can function across multiple cardiac chambers (atria, right ventricle, left ventricle). Each channel can operate as a sensing channel, pacing channel, or both simultaneously, allowing a single device to handle dual-chamber, tri-chamber, and various hybrid pacing configurations, thereby achieving multi-functionality and universality.
2Adaptability or versatility
If more sensing and pacing channels are added to accommodate tri-chamber pacemakers, then testing capability is improved, but device complexity increases
Solution Approach 1:
The PSA system is segmented into three independent sensing and pacing channels, where each channel can be independently controlled and configured. This segmentation allows the complex tri-chamber pacing functionality to be divided into manageable independent units, reducing overall system complexity while maintaining full capability.
Solution Approach 2:
The channels are designed to be dynamically configurable, where each channel can be programmatically assigned to different cardiac chambers and functions based on testing requirements. This dynamic adaptability allows the device to transform between different pacing mode configurations (dual-chamber, tri-chamber, hybrid modes) without requiring physical reconfiguration, thereby managing complexity.
3Adaptability or versatility
If multiple pacing parameters including cross-channel parameters are added, then programming capability is improved, but ease of operation deteriorates
Solution Approach 1:
The PSA includes pre-configured pacing parameters and cross-channel timing relationships that can be programmatically set before actual pacemaker implantation. Standard pacing modes and parameter sets are prepared in advance, allowing clinicians to perform comprehensive testing of multiple pacing configurations without manually calculating and programming each parameter from scratch during the procedure.
Solution Approach 2:
The system provides real-time display of cardiac signals from all three chambers and allows observation of pacing effects across channels. This feedback mechanism enables clinicians to verify proper lead placement and pacing parameter settings immediately, reducing the need for iterative adjustments and simplifying the programming process.

AI summary
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.
