Inadequate blood and oxygen supply to the heart. An ECG done while you're having symptoms can help your doctor determine whether chest pain is caused by reduced blood flow to the heart muscle, such as with the chest pain of unstable angina.
Whether you have conduction abnormalities, which result from issues regarding how the electrical impulse spreads across the heart (such as with a bundle branch block)

Blood then flows into the left ventricle where it is pumped into the aorta and is distributed to the rest of the body. This blood supplies organs and cells with oxygen and nutrients necessary for metabolism.
Conducting system of the heart: SA means sinoatrial node. AV means atrioventricular node. RB and LB mean right and left bundle, respectively, and are the nerves that spread the electric impulse from the AV node into the ventricles.

An ECG recording machine will usually show your heart rhythm and electrical activity as a graph displayed electronically or printed on paper.
A collection of data interpretation guides to help you learn how to interpret various laboratory and radiology investigations.
O exame deve ser executado periodicamente, variando do convénio utilizando a faixa etária e o sexo biológico. Mulheres a partir Destes 50 anos e homens a partir Destes 40 anos devem fazer este exame ECG anualmente.
Your doctor will review the information recorded by the ECG machine and look for any problems with your heart, including:
The electrical signals generated from the electrodes are processed to obtain the heart’s electrical activity from 12 different angles, each of which shows a separate tracing in the form of waves. Different conditions are associated with changes in the height, width, and length of these waves.
