Ecg cardiac cycle

The concept of a mean electrical axis of the QRS complex in the ECG was first introduced by Willem Einthoven in 1913 (Einthoven et al., 1913), and to this day it remains a clinically important aspect of ECG diagnostics. It represents the average direction of the ventricular depolarization wave in the frontal plane, that is, the total vector of all the depolarizations that occur throughout the ventricles during the cardiac cycle. “circle of axes"

Electrocardiography is the process of producing an electrocardiogram, a recording of the heart's electrical activity through repeated cardiac cycles. It is an e...

Cardiac

The single cycle of cardiac activity can be divided into two basic phases - diastole and systole, It is defined as a sequence of alternating contraction and ...

The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these leads are calculated as a combination of leads I, II and III. The six precordial leads are called leads V1, V2, V3, V4, V5 and V6.

Latest Medical News on Instagram: "The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole. After emptying, the heart immediately relaxes and expands to receive another influx of blood returning from the lungs and other systems of the body…
