Systems for safe and remote outpatient ECG monitoring

摘要

A system and method providing outpatient ECG monitoring and safe home based cardiac tele-rehabilitation. The system includes a recordation module for recording ECG signals using at least one lead, a tele-rehabilitation module for home based exercise management for a patient's recovery from a heart disease, the tele-rehabilitation module including a processing module for recognizing erroneous data from the ECG signals and an analysis module for calculating beat-to-beat annotations and determining if an ECG event and/or if a QT interval duration change has occurred. The system can include an exercise module for guiding the patient during an exercise session, a visual display that informs the patient to start and/or to stop the tele-rehabilitation exercise, a visual display and/or audible signal that informs the patient of an incoming or a missed tele-rehabilitation exercise session, and/or a communication module for transmitting/receiving data between the a cardiac tele-rehabilitation module and a physician/monitoring center.

主权项

1. A limited-lead electrocardiogram (ECG) system for remote outpatient cardiac monitoring and tele-rehabilitation, comprising:
a recordation module configured to record ECG signals using at least one lead; a cardiac tele-rehabilitation module configured to manage home based exercise for a patient's recovery from a heart disease, the cardiac tele-rehabilitation module including:
a processing module configured to recognize erroneous data from the ECG signals, wherein the processing module includes and executes a signal pre-processing algorithm (SPA) configured to: i) divide the ECG signals into overlapping blocks, wherein block sizes are related to a calculated average heart rate (HR), ii) calculate a mean value for each of the blocks, iii) subtract, from each of the blocks, the mean value of each block, and iv) reconstruct the ECG signal by cross-fading successive segments;
an analysis module configured to calculate annotations for every ECG beat detected in the ECG signals and determine if an ECG event has occurred based on the annotations, wherein the ECG event is related to a patient's pathological cardiac event;a communication module configured to report the processed ECG signals and/or other detected ECG events including streaming all of the annotations and information describing each ECG beat.
