The electrocardiogram is a test that records the electrical activity of the heart that occurs in each heartbeat. It is recorded from the patient’s body surface and is drawn on a paper by means of a graphic or plotted representation, where different waves are observed that represent the electrical stimuli of the atria and ventricles. The device with which the electrocardiogram is obtained is called an electrocardiograph.

It is used to measure the rhythm and regularity of the beats, the size and position of the atria (represented by the P wave) and ventricles (represented by the QRS complex), any damage to the heart and the effects that certain effects may have on it drugs or devices implanted in the heart (such as pacemakers).

It is a simple, available, rapid test, which does not cause any discomfort (it is painless) and has no risk for the patient (no electricity is sent through the body, it only detects the electrical activity that is generated in the own heart).

How the electrocardiogram is performed

Our staff connects the electrocardiograph wires to the patient’s skin through adhesives or suction cups (electrodes). The points where the electrodes are placed are ankles, wrists and chest. In this way the same electrical impulse is collected from different positions. First you must clean the area of ​​the skin where the electrodes will be placed later, and, even, sometimes it will be necessary to shave the hair of that area.
