It is a diagnostic test that consists of monitoring, on an outpatient basis and continuously for 24 hours, the electrical impulses of the heart (Electrocardiogram) of a person during their usual daily activity by means of a portable equipment called Holter, which is a small electronic device, which records and stores the patient’s electrocardiogram continuously and is usually used in patients with suspected cardiac arrhythmia as a cause of symptoms (palpitations, dizziness, shortness of breath and episodic sweating or loss of consciousness, among others). This study is also useful to diagnose manifest and silent myocardial ischemia (Inadequate supply of oxygen to the heart muscle that in some people is not related to symptoms).
The Holter is positioned on the patient’s waist in such a way that it can be repositioned by him for his comfort. This equipment is connected to conductive cables that in turn are connected to electrodes attached to the patient’s chest skin.
For agility and certainty in the evaluation of the registry, it is very important that the patient records the time of day in which he feels any anomaly that may be related to the inadequate functioning of his heart, which allows the specialist to more easily find, if in fact there is some alteration of the cardiac rhythm that can explain the symptoms referred by the patient.
To carry out this test, the patient must consult the specialist beforehand, to find out what kind of considerations he must have, such as the suspension of some type of drug, in case he is using it and what are the cares that must be taken for the use of the drug. device.
