In a first approach to the concept of ergometry It is interesting to analyze how the word is formed. In its composition we find the Greek word érgon (which can be translated as “job”) and the suffix -metry (referring to a measurement).
The notion of ergometry is used in the field of medicine to refer to a study that allows to measure the effort made by the body or carried out by certain muscles in a given situation. It is a test that makes it possible to specify diagnostics from the results obtained and that serves to evaluate coronary artery disease already diagnosed.
What is ergometry?
Also mentioned as stress test, ergometry requires the patient to perform physical exercise on a stationary bike or in a headband while progressively increasing the effort based on a protocol. Before starting the exercise, you will two electrocardiograms (one standing and the other lying down) and then, with the test already underway, the continuous electrocardiographic evolution. Finally, the cardiac function is also recorded during the recovery period using different methods.
Monitoring requires the adherence of electrodes to the thorax of the individual. Said electrodes, in turn, are connected to a machine.
The ergometry can take between six and twelve minutes. The time of RecoveryMeanwhile, it is estimated between three and five minutes.
The professional of the Health who is in charge of the ergometry should pay attention especially when the instance of the Maximum effort to see if the individual runs out of air or evidence angina pectoris. It is important to mention that the test can reveal cardiovascular disorders that do not appear when the subject is at rest.
A patient may have coronary artery disease that does not impede normal blood flow at rest, but causes problems with physical exertion. This is because exertion increases the job that specifies the heart, which requires a greater blood supply at that particular moment. The blockage of an arteryIn this context, it can cause angina pectoris and other conditions.
Ergometry is considered to be positive if alterations are detected in cardiac monitoring or if the person suffers a pain on the chest while exercising. There are cases of false positives (when ergometry seems to indicate problems that are later ruled out with subsequent studies) and false negatives (if the test is normal but later reveals heart disease that could not be detected previously).
Patient Preparation and Contraindications for Exercise Testing
The patient must go to the place where the exercise test will be performed without having consumed alcoholic drinks or with caffeine and without having ingested one abundant food in the previous three hours. Also you don’t have to have done intense physical exercise in the preceding twelve hours.
It is also recommended to wear comfortable clothes and shoes. The doctor, on the other hand, may indicate the suspension of certain medications the day before the exercise test. Of course, in each particular case, you have to consult the specialist and follow their indications.
Ergometry is contraindicated if the person had multiple angina pectoris or a heart attack in the previous four days or if there is inflammation or a infection. In addition, some neurological diseases, bone problems and lung disorders can make it impossible to perform this test.
