Card Guard was established in 1986. It designs, develops, and markets medical Telemetric and Telediagnostic instruments. The products include several EEG products, one of which replaces the expensive “holter” system often used in short-term ECG monitoring. Other products are a telemetry electrode for on-line broadcasting of the heart rhythm, a product which detects ischemia and arrhythmia while tracking prescribed heart medication. Another product that monitors fetal distress. In addition, the company has also developed a promising diagnostic product – the “Asthma Guard” which allows asthma patients to receive telediagnosis (over the phone) as to the condition of their lung capacity and the severity of their condition.
