IMPEDANCE ANALYSIS FOR ESOPHAGEAL MALADIES |
摘要 |
A system and method for automatically analyzing impedance and pH data from an esophageal probe includes a data collection system that collects and stores the output from the sensors for a certain period of time to locate reflux episodes in the waveforms. The data analysis system uses wavelet analysis to assist in locating bolus entry and exit points in the waveforms and to smooth waveforms for additional analysis. It also distinguishes between candidate acid reflux episodes and candidate non-acid reflux episodes for determining actual acid reflux episodes and non-acid reflux episodes, and it distinguishes between, and provides different signal processing for, signals from patients that have healthy esophageal tissue and those that have diseased esophageal tissue.
