Cubeholter WS - Cubeholter Web
2. SAFETY INFORMATION
If the computer is battery powered, do not connect it to an external power supply (for
recharging) or other electrical equipment (e.g. to another computer via USB or to a LAN
network) when using it in the patient area.
If the computer is powered by the mains, it may not be used in the patient area. When used
in the patient area, it must be powered with an isolation transformer and shielded cables
must be used to connect it to the LAN. The power cable shielding (when present) must be
connected to an earthing system appropriate for the area where the device is used. This will
avoid electric shocks caused by different earth potentials which could exist between the
various points of an electricity distribution system, or else by failures of the external
equipment connected to the mains.
In the event that the computer that this device is installed on is connected to the Internet, it is
recommended to install an antivirus to protect it from unwanted changes. The antivirus must be
configured excluding from the check the folder containing the data, by default:
C:\Users\username\Documents\Cubeholter\data.
If you are printing PDF files, you need to set up a corresponding program so that the document is in
no way adapted or scaled. If you are using Acrobat Reader, you need to select “Actual Size” in “Page
management and size.” Otherwise you may get non-diagnostic quality print outs.
Heart rate is calculated as an average of 4 consecutive normal heartbeats.
An event is classified as a pause if the time between a heartbeat and the next is greater than
2000ms. The value can be set by the user.
Regarding ST analysis:
The ST analysis is performed on all leads. The ST is calculated over a range of 20s, within
which the average heart rate is calculated.
The operator can move point j to calculate the elevation and depression of the ST and can
choose the duration of the ST elevation/depression to be considered as a variation of the ST
segment that is significant for the detection of an ST episode.
The ST page displays the values of the ST variation every 20 s. The trend can be printed in
the PDF report. The number and type of episodes are shown on the ST page, in the strips
and in the table. Duration in the strip of the ST page. This information is provided for each
episode.
Maximum displacement and duration are indicated for each episode.
Attention
The device does not require any calibration or special instrumentation for correct use and
maintenance.
The analysis algorithm is intended for the analysis of ECG tracings acquired with Holter Cardioline
recorders (walk400h, clickholter). The algorithm provides an analysis of the tracings and a
classification of heartbeats and events. Validation by a cardiologist or a doctor is always required.
Cubeholter Web requires ECGWebApp software.

2. SAFETY INFORMATION
Notes
Appropriate patient preparation is important to enable correct application of the electrodes and
patient cable, to minimise the artefacts caused by patient movement and allow proper device
operation.
If the electrodes are not properly connected to the patient, or one or more of the patient's leads are
damaged, the software will indicate these leads as a square wave.
The accuracy of the measurements taken by this device complies with the specific requirement of
standard IEC 60601-2-47.
The device is Class II in compliance with Directive 93/42/EEC.
Losing the pen drive is the same as losing the device and it cannot be replaced.

Analysis window: Data section and Rhythm section
The program consists of the following test analysis windows:
RR: RR analysis
Templates: template analysis
Events: event analysis
ST: ST analysis
QT: QT analysis
28Cubeholter WS - Cubeholter Web
7. VIEW, ANALYSE AND REPORT A TEST
Each window consists of two sections:
Data Section (1): placed at the top, it displays data relative to the parameter being analysed (RR data,
templates, events and so on) and therefore changes for each window;
Rhythm Section (2): placed at the bottom, it displays the leads of the acquired test and has the same
structure in all windows. From the rhythm section it is possible to take measurements on the
tracings and insert, remove or edit a heartbeat or an event.
The following chapter describes the Rhythm section, common to all test analysis windows.
7.4.1. Rhythm section
The rhythm section shows all leads of the acquired signal, 2, 3 or 12 depending on the patient cable used for
acquisition.
By using the controls on the left panel it is possible to change:
Interval displayed: double arrow to scroll slowly, triangle to scroll quickly, scroll with the mouse
wheel to scroll at will;
Displayed leads: active in the compacted display, where it is possible to select which channel/lead to
display and with 12 leads acquired according to the selected format, where it is possible to choose
which set of leads to display, for example if the format is 3 you can choose between I-III, aVR-aVF,
V1-V3, V4-V6)..
Tracing format: 1 (compacted display –in the RR Window only), 3, 12;
Amplitude: 1, 5, 10, 20, 40 mm/mV;
Speed: 5, 10, 25, 50, 100 mm/s;
Filter: enable/disable the display filter
Each heartbeat is marked and classified with a letter and a colour indicating the type of heartbeat:
N green: normal heartbeat;
O grey: unknown heartbeat;
V red: ventricular heartbeat;
AFIB red: atrial fibrillation - the corresponding path is drawn in red;
A: artefacts – the corresponding path is drawn in grey.
P blue: pacemaker heartbeat – the relative trace is in blue (if pacemaker analysis is enabled).
If an event is present (CPT, SVS, etc.) it is indicated and a red vertical line indicating the start time is also
indicated.

Performing measurements on the tracings
It is possible to perform measurements on the tracings by left-clicking on a point of the tracings and scrolling
the mouse, while holding the button down. Two vertical lines and a red area at the centre of them will
appear, corresponding to the area being measured.
Measurements on the tracings
The values measured by the software represent the time in milliseconds between the two measured points,
the heart rate in heartbeats per minute and the vertical difference in amplitude in microvolt between two
points, for example between the isoelectric line and the peak of the R wave.
Entering a new heartbeat
To enter a new beat, select a point in the ECG tracing, where the program has not found any heartbeats,
right-click to open the drop-down menu. Select “Enter” and insert the new heartbeat (choosing between
Normal, Ventricular, Atrial).
Editing or removing a heartbeat
By left-clicking a QRS already recognised by the program, right-clicking opens a drop-down menu from which
it is possible to:
Edit the heartbeat type
Remove the heartbeat
Go to the heartbeat template
By selecting a signal section it is possible to:
Enter/edit an event (also with the E key on the keyboard), selecting more than one heartbeat and
choosing an event from the drop-down list, or typing one or more letters to automatically skip to the
corresponding entry of the drop-down list: It is also possible to define a new event, freely writing the
name of a custom event

7. VIEW, ANALYSE AND REPORT A TEST
Report the presence of atrial fibrillation in an ECG section (also with the I key on the keyboard);
Remove atrial fibrillation (also with the DELETE key on the keyboard);
Edit heartbeat classification;
Cancel the last operation performed;
Make a manual print reservation, also with the P key on the keyboard.
7.4.2. RR Window
The RR window allows a fast and immediate assessment of the technical quality of the recording and the
presence or absence of systematic errors in the automatic analysis.
The RR window has two sections:
RR data (1): displays the data regarding RR/HR, atrial fibrillation and artefacts;
Rhythm (2): displays the leads of the test acquired (see par. 7.4.1).
The summary at the bottom of the window shows atrial fibrillation, artefacts, maximum HR, minimum HR
and average HR of the entire test. By clicking on the maximum and minimum HR value, the corresponding
times in the RR data section and in the rhythm section are highlighted.

By using the controls on the left panel of the Data section it is possible to change:
Data displayed: double arrow to move from one event to another, triangle (enabled only if the
duration of the interval to be displayed is different from the whole test) to move through the various
intervals of the test;
Display type: trend or table;
Duration of the interval to be analysed: complete, 12h, 6h;
Events displayed: Atrial fibrillation (AFIB), Artefacts, pacemaker-induced heartbeat pacing or all.
Browsing the traces
Use the keyboard keys and the mouse to:
Scroll the signal forwards and backwards by a single heartbeat: RIGHT and LEFT arrow key – by
pressing and holding the key for more than 3 seconds the signal scrolls automatically and
continuously (scrolling is stopped by pressing any key).
Scroll the signal forwards and backwards by one page: UP and DOWN arrow key – by pressing and
holding the key for more than 3 seconds the signal scrolls all the pages automatically (scrolling is
stopped by pressing any key).
Select / Zoom on the traces: you can select a point by clicking on the traces with the left mouse
button. The mouse wheel can then be used to zoom in on the signal. When the signal is zoomed you
can select the trace (Selection) and perform measurements (as described below) or drag the
zoomed signal (Drag), by clicking with the left mouse button and holding it while moving. It is
possible to switch from the Selection function to the Drag function and vice versa by pressing the
space bar key or by opening the menu with the right mouse button and selecting the Drag/Select
menu function. If the selection function is active, the mouse pointer is an arrow, while if the drag
function is active the mouse pointer is a hand.

Excluding an event
In the table display, if the signal is considered an artefact, it is possible to exclude the event and recalculate
the value by pressing the DELETE key on the keyboard. This way the 3 previous heartbeats are classified as
artefacts.
7.4.3. Template Window
The Template window allows an evaluation of the events classified according to the different morphologies
of each heartbeat class.
The Template window has two sections:
Templates (1): divided into two main parts displays templates and heartbeats related to the selected
template;
Rhythm (2): displays the leads of the test acquired (see par. 7.4.1).
The summary at the bottom of the window shows templates and their classification.
