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.

Risk determination for ventricular arrhythmia

This disclosure describes techniques for generating a risk stratification indicator based on HRT measurements computed using physiological parameters sensed by an implantable medical device (IMD). In some examples, the HRT measurements may be computed by the IMD based on the physiological parameters. In other examples, the IMD may sense the physiological parameters, and transmit data representative of the parameters to an external computing device, such as an IMD programmer, which then computes the HRT measurements. Exemplary physiological parameters include cardiac signals.
