Abstract
A method and system for determining a patient's risk of ventricular tachycardia are disclosed. The method includes receiving ECG signals from a patient and filtering the collected ECG signals to generate filtered ECG signals. The method further includes identifying a heart vector from the filtered ECG signals, and measuring a velocity of the heart vector movement. A change in curvature of the identified heart vector movement is quantified and a risk of ventricular tachycardia is determined based at least on the measured velocity and the quantified change in curvature of the identified heart vector movement.

A method for identifying a risk of ventricular tachycardia in a patient, comprising:
- receiving ECG signals from the patient;
- filtering the ECG signals to generate filtered ECG signals;
- identifying, in real-time, a heart vector from the filtered ECG signals;
- measuring, in real-time, a velocity of the heart vector;
- quantifying, in real-time, a change in curvature of the identified heart vector;
- localizing, in real-time, an origin of arrhythmia in the patient;
- and
- determining, in real-time, the risk of ventricular tachycardia based at least on the measured velocity and the quantified change in curvature of the identified heart vector.
A system comprising:
- an input module configured to receive ECG signals related to a patient;
- a filtering module configured to filter the received ECG signals to generate filtered ECG signals;
- and
- a processor configured to, in real-time:
- identify a heart vector from the filtered ECG signals, and measure a velocity of the heart vector,
- quantify a change in curvature of the identified heart vector, localize an origin of arrhythmia in the patient;
- and
- determine a risk of ventricular tachycardia based at least on the measured velocity and the quantified change in curvature of the identified heart vector.
A computer program product stored on a non-transitory computer-readable medium, including instructions that, when executed by a computing device, cause the computing device to perform, in real-time, one or more functions, comprising:
- receiving ECG signals;
- identifying a heart vector from filtered ECG signals, wherein the filtered ECG signals are generated by filtering the ECG signals, and measuring a velocity of the heart vector;
- quantifying a change in curvature of the identified heart vector;
- localizing an origin of arrhythmia in the patient;
- and
- determining a risk of ventricular tachycardia based at least on the measured velocity and the quantified change in curvature of the identified heart vector.
