The objective of the electrocardiograph is to search for any pathology in the heart and the effects of treatments and devices on the main organ of the circulatory system, in addition it allows to discover and study diseases such as cardiac arrhythmias, acute episodes of coronary disease and myocardial infarction. It can also be used in preoperative investigations, especially in surgery of medium and high complexity, if there are risk factors such as ischemic heart disease, diabetes, stroke, heart failure or renal dysfunction.
To detect pathologies that affect the health of patients, the medical professional installs electrocardiograph electrodes to the patient’s skin, by means of adhesives, they are connected to the ankles, wrists and chest, to collect electrical impulses from different parts of the body.
Diagnosis of Coronary Diseases
Through the study carried out by the team, the information it requires is very useful, because by researching the electrical activity of the heart, you can discover the rhythm of the heart, the frequency of the heart, if there is an increase in the size of cavities. It also allows diagnosing diseases such as arrhythmias, cardiomyopathy, angina or infarction.
Sometimes, through the electrocardiogram, you may find that your heart is hypertrophy (usually due to high blood pressure) or that your heart is not getting enough oxygen because of a blockage in one of the blood vessels that supply your heart (the coronary arteries).
For the correct result in the studies of the patient at the cardiac level, these should remain calm, and in the case of collecting abnormal information, are then patients with pathologies that interfere in the study, such as:
- Deterioration of the myocardium.
- 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.
Therefore, studies should be conducted in these patients with any symptoms such as chest pain, choking or palpitations, hypertension and in elderly patients, given the higher prevalence of cardiovascular disease at the older age of the patient.
Medical Recommendations for Using the Electrocardiograph in Patients
Generally, the electrocardiograph, is used to rule out any doubt of heart discomfort. It is mainly performed in elderly patients, and even more, when there is conviction of a heart ailment. It can be used, as a platform for comparison with later studies if heart disease occurs.
Since abnormal heart rhythms and insufficient blood flow to the heart muscle may occasionally and unpredictably arise and to detect such problems, the specialist, is duty bound to indicate the relevant study, through electrodes (small round sensors that stick to the skin) on the patient’s arms, legs and chest.
It should be noted, that you must take into account, that the area is free of interruptions, such as thick hair, to be able to measure the magnitude and direction of the electrical currents of the heart, during each beat. Each line that makes up the electrocardiogram shows the electrical activity of the heart from different angles. The procedure takes about three minutes and presents no risks.
Electrocardiographs in Spain
We at Kalsteinoffer you ideal equipment for the study of the pathologies that patients with coronary difficulties throw, and through electrocardiographs that have the ideal characteristics, specialists will be able to fully fulfill their role, to patient care.
