Transtelephonic Cardiac Event Monitoring
QRST announces the latest technology in transtelephonic cardiac event monitoring. The QRST Model 1200m Transtelephonic Cardiac Event Monitor is a small, lightweight unit designed to document the symptomatic patient's pre and post symptom electrocardiographic activity, and transmit the signal to any analog receiving station. Designed to improve patient compliance, the 1200m offers a convenient belt clip holster, and is easy to wear measuring smaller than a standard pager.

With its ergonomic design, the QRST 1200m minimizes false event recordings with a low-profile recording button, and can store up to 5 minutes of ECG. The device offers a variety of memory modes to accommodate the duration of any symptom type, and transmits the ECG with superior signal quality. Testing throughput is accelerated using the device's auto-erase feature. Using advanced computer controlled baseline correction, the
1200m offers the highest quality electrocardiogram available.
