7. Useful advice for creating good quality ECG records
7.1. Requirements for good quality ECG record creation
Innomed Medical ships its devices with silver-silverchloride electrodes.
These electrodes have a low contact potential, and therefore produce better ECG records than
non-silver-silverchloride electrodes.
Please use our devices with the electrodes provided.
Connect the patient cable to the ECG IN connector on the right side of the device. The
connectors on the opposite end of the cable should be connected to the electrodes as shown in
subsections 7.1.1. and 7.1.2.
The patient's skin should be cleaned from body oil and moisturizers, and shaved if necessary
(e.g. in case of a hairy chest).
Before each use, the electrodes have to be cleaned. It is extremely important that no dried gel
remains on the electrodes!
The clamp and suction type electrodes should be applied with gel provided by Innomed
Medical (or other comparable quality gel recommended for ECG use).
Using a wet gauze instead of gel can lead to undesirable results.
If possible, avoid placing the electrodes over muscle masses, as muscle tremors cause a lot of
noise on the record.
During recording, the patient should lie calmly without moving or speaking.
If disposable electrodes are used, check their expiry date.
