Indications for Use

The TZ Medical "FM Demodulator" (4 or 12 lead) is an interface between an event recorder and ECG machine which takes FM frequency received from a heart monitor and translates it back into an electronic signal which can then be read by an ECG machine to provide ECG traces. The device is used with ECG machines which do not have built in "translators".

Device Story

The FM Demodulator (4-lead Model #8500-05 and 12-lead Model #8500-25) functions as an interface device between a heart monitor event recorder and an ECG machine. It receives FM frequency signals from the heart monitor, demodulates/translates these signals into electronic signals, and outputs them to an ECG machine. This allows ECG machines without built-in translators to generate ECG traces. The device is intended for clinical use by healthcare professionals. It facilitates the diagnostic process by enabling the visualization of cardiac data from remote or portable monitoring systems on standard ECG equipment.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

The device is an electronic signal interface/demodulator. It operates by receiving FM frequency inputs and converting them to electronic signals compatible with standard ECG machines. It is available in 4-lead and 12-lead configurations. The device is a Class II medical device (Product Code: DXH).

Indications for Use

Indicated for use as an interface between an event recorder and an ECG machine to translate FM frequency signals from a heart monitor into electronic signals for ECG trace generation. Intended for prescription use with ECG machines lacking built-in translators.

Regulatory Classification

Identification
