It is a specialized medical team that prints the record of cardiac activities, which reflects positive and negative waves, driven by electrodes located in the chest cavities on the patient’s body. This mechanism records whether the heart has any damage, the rate of palpitation or any abnormality, as well as the effects left by the drugs intended for the heart and the position and size of the chambers of the heart.
Its functions capture and print the electrical impulses of the heart of twelve leads per record, which are taken in the selected sequence and can be determined automatically. They also offer numerous advantages, as they allow to compare the records of multiple leads during the same heartbeat, greatly facilitating interpretation and improving accordingly the accuracy of diagnosis.
Characteristics of an Electrocardiograph
This innovative instrument features protection circuit, calibration signal, preamplifier, isolation circuit and amplifier handler, which correspond to an amplifier of biopotentials. It has a connection from the right leg, which creates an active earth isolated from the electrical earth of the circuit, in order to reduce the voltages it receives, and thus increase its safety. It also has a deviation selector, where the module approves the contribution of each electrode through resistors, achieving the derivation of interest.
By using these equipment, it detects the following signals:
- Memory System: this is a memory where the signal is stored before it is printed along with the data that is manually entered via a digital keyboard. A digital analog converter is used to convert the signal.
- Micro Controller: this component controls each procedure performed by the electrocardiograph.
- Registrar: is responsible for printing the signal that the electrodes pick up, that is, the result of the electrocardiogram.
Functions of the Electrocardiograph Operator
The task of operating the equipment is one that is capable of enforcing a simple protocol, which simply consists of the patient staying in position of rest on the stretcher and connecting a series of electrodes with suction cups or adhesives connected to the electrocardiograph. The patient does not have to do any pre-preparation and during the test just be relaxed and breathe normally.
Once the recording is done, the operator must disconnect the equipment and remove the electrodes, then help the patient remove the remaining adherents, and finally help the patient to get out of bed and dress him, if necessary.
The information required by the electrocardiograph is very useful, because by recording the electrical activity of the heart you can detect the rhythm of the heart, the frequency of it, if there is an increase in the size of cavities. It can help diagnose diseases such as arrhythmias, cardiomyopathy, angina or infarction.
If the results are abnormal, it may be due to one of the following conditions:
- Deterioration of the myocardium.
- Arrhythmias.
- Imbalances in the amount of calcium, potassium or other substances in the blood.
- Congenital heart disease.
- Increased heart volume.
- Aftermath of a past cardiac arrest.
- Cardiac arrest at the time.
- Low blood flow in the arteries.
Electrocardiograph in KALSTEIN
We at KALSTEIN, have 12-channel ECG Electrocardiographs is an electrocardiograph that can collect 12-lead ECG signals simultaneously and print ECG waveforms with a thermal printing system. The electrocardiogram is commonly used to detect abnormal heart rhythms and to investigate the cause of chest pains. An electrocardiogram records the electrical activity of the heart. The heart produces tiny electrical impulses that spread through the heart muscle to cause the heart to contract. These impulses are detected by the electrocardiograph.
We have YR models, with 7″ touch screen, Supports Ecg analysis capabilities, 12 standard conductors, input circuit current ≤0.0.05ì, anti-baseline drift automatic, 12.5 mm/s, 25 mm/s, 50 mm/s. For more information, visit us at HERE.
