The devices that form part of the system can only be used with the compatible accessories and
devices indicated in the respective operating manuals.
The Cubestress software must be installed on the computer supplied. The minimum requirements
for the computer are indicated in the operating manual of the Cubestress software.
The devices that form part of the system must be inter-connected as described in the respective
operating manuals.
Attention
The analysis algorithm is intended for the analysis of ECG traces acquired with the HD+ unit. The
algorithm provides an analysis of the traces and a classification of heartbeats, events, calculation of
medians and of the ST/QT section. Validation by a cardiologist or a doctor is always required.
Contraindications
The device may not be used with the following categories of patients:
patients who report discomfort or who suffer from dizziness, nausea or pain;
patients under the influence of substances (alcohol, drugs, medication) that may impair
individual lucidity.
Notes
The movements of the patient may generate excessive noise and affect the quality of the ECG trace
or the correct analysis of the device.
An appropriate preparation of the patient is important in order to guarantee a proper application of
the ECG electrodes and the correct operation of the device.
The incorrect positioning of the electrodes for the detection of the algorithm depends on the normal
physiology and on the order of the ECG leads and it tries to identify the most likely exchange.
However, it is recommended to check the positioning of the electrodes of the same group (limbs or
chest).
If the electrodes are not properly connected to the patient, or one or more patient leads are
damaged, the display will indicate that the leads in question are disconnected. When the ECG is
viewed on video or printed, these leads will be shown on the chart as a square wave.
The accuracy of the measurements taken by this device complies with standard IEC 60601-2-25.
The device is Class II in compliance with Directive 93/42/EEC.
