What is it indicated for?
The MEMORYTRACE™ Model 4224 monitor is a patient-operated device designed to record and transmit a patient’s ECG for the documentation of rhythm and/or rate disturbances. The recorded ECG data can be transmitted over a telephone to a standard ECG receiver. The ECG transmissions are intended as aids in evaluating symptomatic episodes of rate disturbances, post-myocardial infarction follow-ups, anti-arrhythmia therapy, and cases that require ST segment analysis. The intended population is from infants whose weight is greater than 10 kg (22 Ibs) through geriatric patients with no upper limit.
