Read the full statement (112 words)

The CG-7100 Personal Electrocardiogram Telephone Transmitter is a patient

activated cardiac event monitor for evaluation of transient symptoms.

The CG-7100 allows a patient to record non-standard 12 leads electrocardiogram

(ECG) in device memory and transmit the stored data to transtelephonic receiver

located in physician office, hospital or cardiac monitoring center.

This non-standard 12 leads electrocardiogram(ECG), which is measured with

CG-7100, should not be used for diagnostics in comparison to the standard 12

lead ECG obtained at standard electrode placement.

The CG-7100 is suggested to record and transmit ECG’s to physicians for use in

monitoring gross cardiac morphology changes in ambulatory patients for whom

physicians, in their judgment, believe cardiac monitoring is appropriate.

Indications for use read by OCR from a scanned FDA 510(k) statement, so letters may be misread. Check the PDF before quoting it.
