CardioFlux is a medical device capable of passively, and without patient contact, measuring the cardiac generated magnetic fields emanating from a patient’s chest. These signals have been shown to be highly sensitive to a broad spectrum of cardiovascular diseases, including ischemia and arrhythmia. This technology can be wheeled to the bedside of the emergency room, and poses no risk to the patient (i.e. no radiation, injections). The sensitivity and specificity of the system to ischemia in patients with unstable angina has been demonstrated to be comparable to stress imaging, yet can be performed in seconds and without patient risk.
