5.3 Battery Charger
RhythmStar batteries must be charged with the included battery charger.
6. Electrode Application—Connecting the ECG
RhythmStar operates with the supplied patient ECG lead cables only! RhythmStar
can operate with either a 3 or a 5-lead cable. Any attempt to connect another type of
cable could damage the device or cause injury to the patient. Every effort should be
made to handle and store the patient ECG lead cables with care to avoid damaging
the lead wires and lead wires snaps.
6.1 Connecting the ECG cable to the patient
The quality of the ECG signal greatly depends on the contact between the electrode
and the patient’s skin. RhythMedix recommends use of high-quality, Holter
electrodes that have been approved by the FDA. Proper preparation of the patient’s
skin is required for obtaining a quality ECG recording. It is best to refer to your
electrode manufacturer for instructions on proper skin preparation techniques.
However, the following points can assist in obtaining quality ECG recordings:
If necessary, shave hair from the areas on the chest where the electrodes are to
be placed.
At each location where an electrode is to be placed, clean the skin with water or
rubbing alcohol
and let the skin dry.
To avoid applying excessive pressure to the patient’s body, attach the snaps of the
ECG cabl
e to the electrodes prior to placing them on the patient’s skin.
Generally, electrodes should be placed over bone structures. Artifact and noise
result from placem
ent of electrodes over large muscles or fatty tissue.
NOTE: RhythmStar device is intended to be used with 3rd party lead electrodes
supplied to a patient by a physician or a monitoring center. High quality FDA ap-
proved lead electrodes should be used.
