Moreover, the necessary procedures for choosing the correct recording parameters, such as "speed, sensitivity and inserting the filters", are illustrated. Connect the terminal plug of the patient cable to the connector identified with the symbol , positioned on the right side of the device. Note: to avoid breaking the patient cable, remove it from the connector without tugging it, gripping it by the plug. Warning: the device is internally protected against defibrillation discharges; in order to guarantee the resetting of the signal, it is necessary to use protected electrodes.
To ensure that safety conditions are respected, use only original accessories. First, make the patient comfortable, he should be warm and relaxed as much as possible; he should lie on his back on an examination bed or table of adequate size with his arms and hands relaxed along the sides of his body: this will minimize the likelihood of trace interference originating from muscle tremor.
Thoroughly clean the skin where the electrodes will be placed with alcohol or ether. Connect each unipolar plug of the patient cable distinguished by colour coding to the respective electrodes, observing the colour-position relationship indicated below:. The following figure shows the standard positioning of the electrodes.
Standard positioning of the electrodes V1: on the 4th intercostal space along the right parasternal line; V2: on the 4th intercostal space along the left parasternal line; V3: on the 5th rib, between V2 and V4; V4: on the 5th intercostal space, on the left hemiclavicular region; V5: on the left anterior axillary, at the same level as V4 ; V6: on the left mid-axillary at the level of V4; peripheral electrodes: generally a few centimeters above ankles and wrists.
Warning: make sure that the conductive portions of the electrodes are not touching each other or other metallic parts. In any case, series original electrodes, of silver and silver chloride, are designed and manufactured in order to minimize the likelihood of accidental contact between conductive parts and external metal objects.
Ensure that the machine is not affected by disturbances originating from the power supply network see paragraph "Initial preparation". The possible choices During printing, the speed of the paper flow is indicated by the width of the calibration impulse that precedes each lead and is recorded in the information line. During printing, the sensitivity of recording on paper is indicated by the height of the calibration impulse that precedes each lead and is recorded on the information line Note: if you select the sensitivity is set automatically by the device in a way that optimizes the recording over the entire height of the paper.
In this case a sensitivity of 2. This option is recommended during multi-channel printing. To know how automatic sensitivity is determined, see the paragraph "Technical Characteristics". Recording filters If necessary, it is possible to activate filters capable of improving the legibility of the signal without modifying its morphology.
Activation of the filters has an effect on the printed signal. To guarantee a correct and accurate analysis, any automatic interpretation of the trace is performed always and only on the non-filtered ECG signal.
The filters available have been designed to reduce the effect of both mains disturbances and muscle tremors. The special filter against drift of the isoelectric line ADF is always inserted. During printing, the filters inserted are recorded on the information line. Caution: the use of the filters of your ECG is very effective for attenuating disturbances and does not reduce the diagnostic content of the traces. Nevertheless, it is recommended to eliminate the cause of the interference and not just the visible effect on the trace see paragraphs "Troubleshooting"; "Initial preparation".
The signal is recorded in real time, i. When operating in manual mode it is possible to establish the duration of registration independently for each group of leads starting from D1 D1, D2, D3 in multi-channel print format. If the signal has not yet been initialized the LED lights up momentarily.
Note: during a manual recording it is possible to alter the recording characteristics: speed, sensitivity, filters. An automatic recording allows you to run calculation and analysis programs on the traces available "ECG measurement" option , to obtain a copy of the recording and to transfer the test to a Computer "PC archive" option. At the end of acquisition, 10 seconds, the LED blinks, indicating that the signal has been completely stored in the memory. It is now possible to disconnect the patient.
If the signal is already in memory LED blinking it will still be possible to print a copy of the recording. Automatic calculation of the ECG parameters 5 The program for automatic measurement of the ECG parameters allows you to obtain a report of the principal measurements calculated at the end of each automatic recording. Start: automatic at the end of the recording Stop: automatic at the end of printing the report The principal items of information in the report are: - The average ECG complex for the ECG lead with the greatest ST level deviation.
If any of these parameters are outside of normal limits they are flagged with an asterisk; - representation of ECG rhythm.
Caution: if it is not possible to calculate the measurements, a message is reproduced on paper "Measurements or analysis impossible due to the poor quality of the signal". This situation may be due to excessive noise of the ECG trace or to incorrect positioning of the electrodes. Copy of an automatic ECG recording The ECG recording in automatic mode and the respective analysis, if processed automatically, are automatically memorized and can therefore be reproduced on paper an unlimited number of times.
If the memory does not contain valid data, the message "No ECG trace in memory" is printed. Note: memorization of the trace is performed without filtering the signal, notwithstanding the operation of filters during the recording. The parameters may therefore be modified before printing: inserting the filters, speed and sensitivity. Caution: each new acquisition cancels the ECG trace previously stored in the memory!
For details on the use of the application software, consult the specific manual. Place the electrocardiograph in position with respect to the infrared adapter previously connected to the PC. Caution: to assist correct data transmission, position the IR adapter for PC at a distance of no more than one meter.
Avoid placing objects between the two interfaces. Your ar therefore becomes an acquisition system based on a PC. During transmission the LEDs blink. Within 10 seconds of the discharge, the signal is automatically reset if the paper reproduction of the. The approved electrodes supplied as original equipment with your electrocardiograph were developed so as to minimize the risk in case of accidental contact.
The operation of the electrocardiograph depends on the current operating phase. Stop phase LED blinking: critical electrodes contact.
It is possible to proceed with the recording; the "critical" electrodes are indicated on the print report in the information line for example " L 1 " indicates the critical nature of the left arm electrode and of the electrode C1. LED on: electrodes disconnected saturation. It is not possible to start an automatic recording. A manual recording may be started; the "disconnected" electrodes are indicated on the print report in the information line and a flat signal will be reproduced on paper corresponding to the lead that cannot be acquired due to the absence of an electrode for example " L 1 " indicates the saturation of the left arm electrode and of the electrode C1.
Manual recording phase The event is indicated as in the stop phase. When normal conditions have been restored, the signal is centred.
Automatic recording phase If the event is detected during acquisition 10s , the ECG is stopped and automatically returns to the stop phase If the signal is already in the memory, printing continues without interruptions. The indication of the event is the same as in all the other phases. Follow the indications supplied in the paragraph "Installation and initial preparation". Out of paper The correct closure of the paper cover is monitored and depletion of the thermal paper generates a warning signal.
During a recording, printing is Measurements or analysis impossible due It is not possible to perform automatic to the poor quality of the signal calculation of the ECG measurements because the signal is too noisy. No ECG trace in memory Impossible to obtain copy of the last recording. X-rays, Ultrasound etc. Excessive noise on the ECG - defective patient cable - defective electrodes.
Access to the self-test menu is accomplished from the "setup mode". Before starting the self-test procedure, ensure that there is paper in the machine. Anomalies of the printing system are detectable by non- continuous lines. Notify the information listed in all communications with the Assistance Centers. Out of paper". Do not use other chemical products or household detergents. For the electrodes: remove the electrodes from the patient cable and wash under running water.
Do not scratch the electrodes and do not wet the leads box and the patient socket. Note: the device cannot be sterilized! The electrodes can be sterilized with oxide of ethylene.
