Heart Stimulators TRIZ Cases
- His Bundle Timing Detection in Implantable Cardiac Devices
Implantable cardiac devices derive His bundle timing data using digital signal processing on atrial and ventricular lead signals.
- Phrenic Nerve Detection in Cardiac Pacing via Respiratory Phase Analysis
Cardiac rhythm management system detects phrenic nerve activation using impedance sensors and accelerometer data to identify respiratory phases.
- External Pacemaker Biatrial Stimulation Threshold Control
External pacemaker segments control circuits to determine individual stimulation thresholds for left and right atria.
- Closed-Loop Rate Response Modulation via VA Interval Monitoring
A closed-loop pacing system modulates heart rate by monitoring the ventricular-atrial interval to maintain physiological timing.
- Leadless Pacemaker Atrial Detection via Multi-Timer Segmentation
Segmented timers extrapolate atrial timing from ventricular signals, enabling reliable VDD pacing without direct atrial measurement.
- Anodal Cathodal Capture Discrimination in Cardiac Pacing
Implantable device discriminates anodal from cathodal capture via evoked response sensing to prevent unintended heart activation sequences.
- Lead-Carried Proximal Electrode for Quadripolar Impedance Monitoring
Forming an electrode on the lead reduces canister complexity and manufacturing costs while maintaining measurement precision.

Active implantable medical device collects endocardiac acceleration signals to evaluate patient clinical status.
- Multi-phase Cardiac Stimulus Generator for Heart Failure
A multi-phase cardiac stimulus generator applies sub-threshold biphasic waveforms to the heart.
- Charge Balancing Circuit for Functional Electrical Stimulation
A charge balancing circuit uses an amplifier and compensation stage to drive electrode voltage within safe limits.
- Remote Cardiac Stimulation for Ischemic Tissue Protection
Remote conditioning triggers intrinsic protective mechanisms to shield the heart from ischemic damage without causing harmful myocardial contraction.
- His-Bundle Pacing Capture Verification via Far-Field Ventricular Activation
A His-bundle pacing system verifies capture status using far-field ventricular activation sensing to determine cardiac synchrony indicators.
- Anodal Stimulation Detection for Cardiac Pacing
Device switches electrode polarity to discriminate anodal from cathodal stimulation, reducing energy consumption while maintaining reliable cardiac capture.
