METHOD OF DETECTING AND PREDICTING NEUROCARDIOGENIC SYNCOPE

[Category : - HEALTH]
[Viewed 29 times]

A method of detecting an early onset of neurocardiogenic syncope in a patient uses respiratory functions as a predictor of the syncope. According to the method, at least one sample of baseline minute ventilation, tidal volume and respiratory rate of the patient is obtained. The detection unit is set to detect an increase in tidal volume and in minute ventilation over a predetermined respiratory period. The detecting unit also detects any rate of change in respiratory rate and sends a signal to a microprocessor to determine whether the increase in minute ventilation is a sole function of increased tidal volume. The impending syncope is diagnosed if variance in respiratory rate is less than 25% in relation to the sampled baseline during the predetermined period of time.

Financial information

This algorithm can be incorporated into wearables, event monitors, pacemakers, defibrillators, Holter monitors, hospital and field telemetry and airplane cockpits. It is a a surrogate for brain perfusion which allows monitoring of brain perfusion and cognitive function under different situations. It will help with discrimination algorithms to determine whether therapies needs to be delivered, provide a warning system to avoid injury and help discern whether cardiac rhythms are providing adequate perfusion.
