IQmark Digital ECG Operation Manual

The live ECG screen displays the results of the 12-channel ECG in the three-by-four (3x4)

leads display format. This format can be changed by using the Settings function. Your

facility’s name, the date, time and the patient’s heart rate appear at the top of the

screen. The ECG tracings are in the center of the screen moving from left to right.

Below the moving tracings are the sweep speed, gain, and filter settings. You can click

the appropriate button to modify its setting. Changes to these settings made from this

screen are temporary and only apply for as long as you are in this test. You can change

and set them as the default settings for all new ECG tests by clicking Settings.

Clicking on INST resets the ECG module and stabilizes the ECG baselines. If there is no

INST button on the screen, manually turning the ECG module power off for one second

and then turning it on would accomplish the same effect.

In the lower-right corner of the screen are the status indicators for ECG Report and RR

Variability. An empty status indicator means that you have not acquired the specific

report since entering the screen. Once a report is created, the indicator next to the test

type appears solid. This indicator is not affected by tests that were previously stored or

reviewed in the database.

The menu bar at the bottom of this screen provides different options you can take.

These available options change according to the settings and the process you have

made.

Prints the last 10 seconds of ECG data being collected. This report contains no

measurements or diagnostic statements. If data is not actively being collected,

this function prints out the last 10 seconds of data in memory.

 NOTE: Clicking Print more than once before the report is printed produces

multiple printouts. Exit is disabled until the report is printed. To

speed up printing, click Freeze before clicking Print.

Analyze

Performs resting analysis on the last 10 seconds of data and stores this

analysis as an ECG Report, which can be printed from the Report Review

screen or by selecting Print After Analysis in the Printer Format Settings.

Freeze

Freezes the display and copies the last 10 seconds of ECG data into a memory

buffer. If there are less than 10 seconds of ECG data collected, the freeze

function is delayed until the 10-second buffer is filled. Click this button a

second time to unfreeze the display and clear the memory buffer. When the

display is frozen, you can also click Print or Analyze.

Display

This option is only available if the Display Real-time ECG Tracing setting is

disabled. Click on this button to display the ECG tracing acquired in the last 10

seconds. Tracings are displayed in static form and are not stored. Click on the

Analyze button to analyze and save the ECG displayed.
