IQmark Digital ECG Operation Manual

III. Operation

WARNING

The IQmark Digital ECG module has been designed and tested to meet IEC 60601-2-25

and AAMI EC11 defibrillation protection standards. In the event of defibrillation,

follow the instructions on your defibrillator and adhere to all warnings and cautions.

A. Introductory Notes

This manual describes how to use the various IQmark Digital ECG features in the

operational sequence most new operators will follow. However, this does not mean that

you are restricted to following this particular sequence. Many of the features are

interconnected and can be accessed from more than one screen. The menu bar, buttons

or tabs on each screen lead you to a different screen or feature. To enter any of these

screens, click once on the appropriate selection.

Of course, there are certain sequences that must always be followed, such as entering a

patient’s medical data prior to acquiring an ECG. Overall, we believe that you will find

this program to be both user-friendly and flexible.

For your convenience, we have included a condensed guide to the operation of the

IQmark Digital ECG with new patients in Appendix-A, Operations at a Glance.

B. Preparation

Careful preparation of the patient’s electrode sites is a prerequisite for obtaining an

interference-free ECG and accurate result. The skin is naturally a poor conductor of

electricity and frequently creates artifact that distorts the ECG signal due to dry or dead

epidermal cells, oils, sweat and dirt. By performing methodical skin preparation, you

greatly reduce the resistive barrier that causes muscle noise and baseline wander,

ensuring high-quality signal and test data.

NOTE: The live ECG acquisition screen will show the signal tracings after all limb

leads have been connected. When the right-leg (RL) lead becomes detached,

the system behaves as if all electrodes were disconnected.
