The ST Segment • LITFL • ECG Library Basics

WebThe period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( Figure 19.3.1 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole. WebThe QRS complex (ventricular complex): normal and abnormal configurations and intervals. A complete QRS complex consists of a Q-, R- and S-wave. However, all three waves may not be visible and there is always variation between the leads. Some leads may display all waves, whereas others might only display one of the waves. h g white artist https://rixtravel.com
