Introduction

Your OMRON HCG-801 is an easy-to-use electrocardiograph unit that can record and store electrocardiogram (ECG) measurements of your heart rhythm. Each ECG reading records about 30-second measurement and these ECG readings can help your doctor monitor your condition. It also includes guidance screens to help you obtain good results when taking measurements.

The monitor is supplied with an SD memory card that can store up to 300 measurements, which include the ECG data along with the date and time of measurement. Storing ECG data on the SD memory card, or in unit memory, allows you or your doctor to view them later.

Intended Use

Medical Purpose The device is used for recording electrocardiographic

waveform when patient feels symptoms of arrhythmia.

Intended User Self-recording by patient Patient Population It is not intended to use for infants weighing less than 10 kg. Environment The device can be used anytime except in the cases

stated in the sections of warnings and cautions in the

instruction manual.

Measurement Parameter Electrocardiograph (ECG) Precautions for use Warnings and cautions described in the instruction manual

should be observed.

Important: Please note that while the measurements from an ECG monitor are a

useful guide for your doctor, they cannot detect all changes in heart conditions. Always consult your doctor if you notice any change in your condition, regardless of the measurement results. Consult a doctor even if “Stable waveform.” is displayed as the measurement result, if you have been diagnosed with a heart condition.

* The illustrations used in this manual may differ slightly from the appearance of the actual product.

5. Important Notes on Taking a Measurement

In order to obtain a good ECG reading, it is important that measurements are taken correctly.

Before taking a measurement for the first time, read these instructions carefully and make sure you observe the following points each time you take a measurement.

• Make sure that the electrodes are directly touching your skin.

• If your hands or skin are dry, wipe them with a damp towel so that they are slightly moist.

• If the electrodes are dirty, wipe any dirt off with a soft cloth moistened with disinfectant alcohol or a cotton swab.

- Take care not to use too much disinfectant alcohol when cleaning the electrodes.

- Do not wipe or get disinfectant alcohol on parts other than the electrodes.

• Do not move during measurement.

- Movement, including talking, coughing, or sneezing, during measurement can affect the

measurement results.

• If the position of your finger or arm is inappropriate during measurement, the results may be unreliable, so be sure to check their position before taking a measurement. (Refer to p. 22 and p. 23.)

• After taking a measurement, disinfect the electrodes by wiping them with a soft cloth or cotton swab moistened with disinfectant alcohol. If you do not disinfect the electrodes there is a risk of skin disease.
