HEARTVIT-PC ergometer system

• 12-channel exercise & resting ECG

• Superior ECG trace quality during ergometer test.

• The system consists of the module HEARTVIT-PC and Scope software that runs in Windows OS.

• The Scope ECG interpretive software is highly accurate

• Database for the resting and exercise recordings

• ECG reports are printed on A4 paper

• Graphical representation of exercise process and measured ECG parameters

• Automatic ergometer bike and treadmill control

• Weight: 150g

The Scope ECG software characteristic

The program supports standard exercise protocols for treadmill (Bruce, Balke, Naughton, Ellestad, Cooper).

Tthe doctor can define his/her own test protocols on treadmill or ergometer bike.

The protocol consists of pre-exercise stage, several main stages and recovery stage.

The transition to the next stage can be initiated automatically, after the stage-defined time is elapsed, or manually (by pressing the Next button).

The Scope's main window during the test is shown on figure 3.

The user can select the set of leads, change the amplitude and speed, set the signal's appearance in one or two columns.

During the test, the program gives:

• Numerical values of heart frequency, target frequency, blood pressure, current load values (W or METS) and time elapsed from the beginning of the test

• Trend graphs of heart frequency and load (W or METS)

• Trend graphs of ST level and slope for leads D2 or V5

• Bar-graph of ST level and ST slope for all selected leads (Fig.3)

• The current ECG signals can be compared with the referent ones that are stored at the test beginning. Both the present and referent signals are displayed on the screen.

• Up to 15 ECG recordings can be stored.vAfter the test is finished, the recordings can be opened and analyzed.

• The recordings are stored automatically (after the stage-defined time is elapsed) or manually (by the pressing the button).

After the test is finished, the program displays:

• Main window - Trend graphs of heart frequency, load, ST level and slope; table with important information gathered during the test (Fig.4)

• ST Trends - Trend graphs of ST level and slope for all selected leads.

• Stage Comparison window - comparison of ECG signals from different stages of exercise test (Fig.5).

• Rhythm window - The complete ECG recording for leads D2 and V5. (Fig.6).
