It is a well known fact that Heart Rate Variability decreases after a myocardial infarction. A decreased HRV identifies patients at high risk of death (i.e.sympathetic stimulation / parasympathetic inhibition).

Patients can be stratified according to this and the knowledge will allow for timely treatment for those at risk. High-risk sub-groups identified by this measurement are candidates for additional therapy (e.g. implantable cardioverter defibrillator therapy)

There has been no device that has been able to do this measurement in real-time and show immediate results.

The ANSiscope is the first instrument that has the potential to be used in this life-saving application.

Another application is the dosage of beta blockers for cardiac patients. This can be done quite accurately, using the ANSiscope.
