Spyder Pro functions as an extended Holter ECG Monitor with event recording function. As an extended Holter Monitor, it can record ECG indefinitely with no time limits, unlike existing Holter Devices which can only record up to 72 hours and information has to be downloaded to the service provider for analysis.
Spyder Personal functions as an Event Monitor which captures the cardiac episode, upon patient trigger. Importantly, unlike usual event monitors, it sends 2.5 minutes of data prior to, and after the time stamp, allowing user to specifically tie in any abnormal symptom to the ECG reading. Current monitors often miss the actual event, as by the time the monitor is worn, the event has already passed. In addition, existing ECG event monitor records only a snap shot (symptomatic) event usually between 30-45s duration.
