Profile: Harbinger Medical, Inc. develops Wedensky modulation technology into a non-invasive risk stratification system. Harbinger MI-1000 system consists of a computer console with printer, proprietary software, a proprietary single-use electrode set and pictures of its patented single use electrode set. This system provides a non-invasive, twenty minute test performed on patients at rest which furnishes information for at-risk patients by assessing the vulnerability of the heart to potentially lethal arrhythmias. This system evaluates cardiac electrical vulnerability by analyzing the changes in a patient's myocardial tissue that are caused by sub-threshold stimulation during depolarization and repolarization of the cardiac cycle. This system is also used for patient's physical health and concurrent medical treatments.
