Meditech Merlin One-channel ECG Event Monitor built in Wristwatch



Patients present with a variety of possible cardiac symptoms that are often difficult or impossible to detect during their office visit with an ECG tracing. The miniature merlin ECG event recorder from Meditech was designed with this in mind, extending cardiac event recording times to weeks. This post-event, single-channel ECG recorder is built into a normal-size wristwatch. As transient arrhythmias and related symptoms may appear spontaneously without warning, it is important to have a recorder that is promptly activated in any circumstances without drawing unnecessary attention to the patient. Requiring no chest contact, merlin is easily activated by placing a hand on the face of the event recording watch.

It can record and store up to 15 minutes of ECG. Flexible programming ensures multiple measures not limited to a preset recording length - merlin can store long or short strips to reflect any of the events. Remaining memory capacity and heart rate calculated from the recorded strip are displayed after each recording. Recordings are easily transmitted to the PC via an optical cable or using a standard modem. With normal use, merlin is expected to provide several months with the same batteries.
