WebAug 23, 2024 · An electrocardiogram (ECG) records the flow of electrical current on three distinct waves. Explore the purpose of an ECG, the three wave types, and the purpose of each wave on an ECG. WebThe ECG machine processes the signals picked up from the skin by electrodes and produces a graphic representation of the electrical activity of the patient's heart. The basic pattern of the ECG is logical: electrical activity towards a lead causes an upward deflection. electrical activity away from a lead causes a downward deflection.

WebJan 31, 2024 · The electrical impulse then reaches the ventricles. This can be seen in the Q, R and S waves of the ECG, which is called the QRS complex. The ventricles contract. Then the T wave shows that the electrical impulse has stopped spreading, and the ventricles relax once again. Heart diseases and irregular heartbeats can be detected in ECGs. WebMar 12, 2024 · When the wave of electricity reaches the AV disc, it is stopped, except in the AV node. The impulse travels through the AV node at a slow, controlled rate toward the ventricles, so there is a pause in the electrical activity on the EKG, referred to as the PR interval. This is shown by the solid red line on the EKG in this figure.

WebThe WPW ECG, seen in the diagram, shows a short PR, delta wave, and somewhat widened QRS. Sino-Atrial Reentrant Tachycardia: This is a rare form of PSVT where the reentrant circuit is between the sinus node and the right atria. The ECG looks like sinus tachycardia, but the tachycardia is paroxysmal; i.e., it starts and ends abruptly. WebRelate heart sounds detected by auscultation to action of heart’s valves. The 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.
