Electrocardiography TRIZ Cases
- Cardiac Signal Derivative Analysis for Body State Transitions
Deriving second interval changes from recurring cardiac signal features to detect physiological transitions.
- Leadless Pacemaker Synchronization via Subcutaneous Trigger
A leadless intracardiac pacemaker synchronizes pacing pulses using a subcutaneous sensing device to eliminate transvenous lead complications.
- Wearable Sensor Electrode Contact Detection Circuit
Control unit calculates electrode resistance values to detect detachment and prevent false heart rate alarms.
- Apnea Detection via Heartbeat-Synchronized Chest Impedance Filtering
A chest impedance detection system re-samples signals based on heartbeat cycles to isolate respiratory data.
- Thoracic Cavity Sensor Placement for Motion Artifact Reduction
Implantable physiological sensors positioned within the thoracic cavity beneath the xyphoid process minimize skeletal muscle interaction.
- Heart Stimulator Optimizing Pacing via Intracardiac Impedance
A heart stimulator calculates a cardiac performance index from intracardiac impedance signals to optimize atrioventricular and interventricular delays.
- Smart Mask Integrating Sensors for PAP Therapy Monitoring
A wearable mask integrates electronics to deliver positive airway pressure while measuring vital signs.
- ECG R-Trigger Stability Monitoring for Extracorporeal Support
Evaluation unit maps ECG data sets to detect R-trigger temporal distance variations, correcting asynchronous control caused by signal noise.
- Cardiac Map Point Cycle Length Equalization
Resampling cardiac signals equalizes native cycle lengths across map points, eliminating data variability caused by physiological rhythm differences.
