In a conventional 12-lead ECG, ten electrodes are placed on the patient's limbs and on the surface get more info of the chest. The overall magnitude of the heart's electrical potential is then measured from twelve different angles ("leads") and is recorded over a period of time (usually ten seconds).
An ECG lead is a graphical representation of the heart’s electrical activity which is calculated by analysing data from several ECG electrodes.
Determination of rate and rhythm is necessary in order to make sense of further interpretation. Axis[edit]
1 resultado por ritmo sinusal significa qual o coração está a bater num ritmo uniforme entre 50 e 100 BPM. Isto ocorre quando as cavidades superiores e inferiores estão sincronizadas.

Whenever the direction of electrical activity moves towards a lead, a positive deflection is produced.
Heart rate. Normally, heart rate can be measured by checking your pulse. An ECG may be helpful if your pulse is difficult to feel or too fast or too irregular to count accurately.
