Internet-based system for evaluating ECG waveforms to estimate the degree of coronary blockage

摘要

The present invention provides an improved, Internet-based system that seamlessly collects cardiovascular data from a patient before, during, and after a procedure for EP or an ID. During an EP procedure, the system collects information describing the patient's response to PES and the ablation process, ECG waveforms and their various features, HR and other vital signs, HR variability, cardiac arrhythmias, patient demographics, and patient outcomes. Once these data are collected, the system stores them on an Internet-accessible computer system that can deploy a collection of user-selected and custom-developed algorithms. Before and after the procedure, the system also integrates with body-worn and/or programmers that interrogate implanted devices to collect similar data while the patient is either ambulatory, or in a clinic associated with the hospital. A data-collection/storage module, featuring database interface, stores physiological and procedural information measured from the patient.

主权项

1. A system for evaluating a degree of blockage of a test patient's heart, comprising:
an electrocardiogram (ECG)-measuring system configured to measure an ECG waveform from the test patient; and a computer system comprising
a database stored on a non-transitory storage medium operably linked to the computer system, the database comprising a set of data fields wherein each data field in the set corresponds to an individual patient in a plurality of comparison patients and wherein each data field comprises an ECG waveform and a parameter indicating a degree of blockage of an artery feeding the individual comparison patient's heart, wherein the database is operably connected to the ECG-measuring system to receive the test patient's ECG waveform and store the test patient's ECG waveform in a data field corresponding to the test patient, an ECG-analysis software system configured to
(i) receive the ECG waveforms from the database corresponding to each individual comparison patient in the plurality of comparison patients and to process the ECG waveform in each data field to extract a set of parameters from an individual comparison patient's ECG waveform,(ii) correlate the set of parameters to the degree of blockage of an artery feeding the individual comparison patient's heart,(iii) processes multiple data fields to determine an average correlation factor mapping the set of parameters to the parameter indicating the degree of blockage of an artery feeding each individual comparison patient's heart, and(iv) evaluate the degree of blockage of the test patient's heart by extracting a new set of parameters from the test patient's ECG waveform, and then comparing the new set of parameters to the average correlation factor to estimate a new parameter indicating the degree of blockage of an artery feeding the test patient's heart.
