Acquisition of ECG information is initiated by the patient, normally in response to encountered symptoms. The Model 471 Sentinel Recorder acquires a single channel of FCG. The Model 472 Sentinel Recorder acquires one or two channels of ECG. The Models 471 and 472 Sentinel Recorders are intended to be used as an ECG Cardiac Monitoring Instrument. The Models 471 and 472 Sentinel Recorders are not suitable for monitoring infants: weighing less than 22 (10 kg) pounds. ## Device Story Sentinel Models 471/472 are ambulatory ECG recorders; capture brief ECG episodes initiated by patient upon symptom onset. Model 471 records single-channel ECG; Model 472 records one or two channels. Solid-state loop recording technology; patient-activated. Used in clinical or home settings; operated by patients. Output consists of stored ECG data for physician review to assist in cardiac rhythm diagnosis and clinical decision-making. ## Clinical Evidence No clinical data provided in the document. ## Technological Characteristics Solid-state ambulatory ECG recorder; single-channel (Model 471) or one/two-channel (Model 472) acquisition; loop recording capability; patient-initiated event capture. ## Regulatory Identification A telephone electrocardiograph transmitter and receiver is a device used to condition an electrocardiograph signal so that it can be transmitted via a telephone line to another location. This device also includes a receiver that reconditions the received signal into its original format so that it can be displayed. The device includes devices used to transmit and receive pacemaker signals. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
