WebNov 11, 2024 · The cardiac cycle is the sequence of events that occurs when the heart beats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of … WebThe T wave results from ventricular repolarization and signals the beginning of ventricular relaxation. The electrical signal for atrial repolarization is masked by the larger QRS complex. In addition to the wave components of the ECG, there are intervals and segments. An interval is part of the ECG containing at least one wave and a straight line. WebDisturbance in ventricular relaxation results in the disruption of pressure conditions in the left ventricle. Ventricular pressure should drop rapidly and substantially during diastole, but if relaxation is impaired, the drop in pressure will be slower and less pronounced. This ultimately leads to increased diastolic pressure in the left ventricle. somerville dance academy richmond hill
