Risk determination for ventricular arrhythmia

摘要

Risk determination for a near fatal ventricular arrhythmia of a patient. An electrocardiogram of a heart of the patient is obtained. A parameter is measured, using an electrocardiogram of a heart of the patient, indicative of an autonomic nervous system of the patient. A numeric score is assigned for the parameter indicative of the conduction system of the heart. A numeric score is assigned for the parameter indicative of the autonomic nervous system. A ratio of the numeric score of the parameter indicative of the conduction system of the heart of the patient and the numeric score of the parameter indicative of the autonomic nervous system of the patient is calculated. The risk of the potentially near fatal ventricular arrhythmia of the patient is determined to be significant if the ratio is greater than a predetermined threshold. An action responsive to the determining step is taken.

主权项

1. A system for determining a risk of a potentially near fatal ventricular arrhythmia of a patient, comprising:
an implantable medical device configured to:
obtain an electrocardiogram of a heart of said patient;measure, using said electrocardiogram, a parameter indicative of a local conduction system of said heart of said patient;measure, using said electrocardiogram, a parameter indicative of a global autonomic nervous system of said patient; said system being configured to:
assign a numeric score for said parameter indicative of said local conduction system of said heart of said patient;assign a numeric score of said parameter indicative of said global autonomic nervous system of said patient;calculate a ratio of said numeric score of said parameter indicative of said local conduction system of said heart of said patient with said numeric score of said parameter indicative of said global autonomic nervous system of said patient;take an action responsive to said risk of said potentially near fatal ventricular arrhythmia of said patient being significant if said ratio is greater than a predetermined threshold.
