The resting ECG is the basic record of electrical changes occurring in the heart muscle during contraction and diastole. In a normal heart, the source of electrical impulses is usually the sinus node, which, producing this impulse, is conducted through the network of fibers within the heart muscle, causing the muscle to contract. This allows you to generate the so-called “Heart throw”, or blood, to the largest artery in our body – the aorta. This in turn carries blood through a network of other arteries to all organs of our body. The proper functioning of this system is necessary for the contraction of the ventricle, which ensures life for all of us. Serious complications, including arrhythmias threatening cardiovascular arrest, can occur if changes occur in the electrocardiogram that interfere with its proper functioning. The electrical image of the heart can be, non-invasively, recorded in the form of an electrocardiogram with the help of electrodes, which will enable the cardiologist to assess its proper functioning.
The test enables:
- recording of rhythm and conductivity,
- evaluation of the work of the pacemaker,
- abnormalities in the blood supply to the heart muscle, including the diagnosis of myocardial infarction,
- it is often helpful in assessing changes in the heart associated with conditions other than heart disease.
