WebAn EKG measures electrical activity of the heartbeat, which is your body’s way of moving blood. Heartbeats are created by an electrical impulse … WebAn electrocardiogram (EKG, ECG) is a test that measures the electrical signals that control heart rhythm. The test measures how electrical impulses move through the heart muscle as it contracts and relaxes. ... The spikes and dips in the line tracings are called waves. The P wave is a record of the electrical activity through the upper heart ...

WebThe QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG).It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the heart and contraction of the large ventricular muscles.. In adults, the QRS complex normally … WebThe different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. The ECG is recorded at a speed of 25 mm/sec (5 large squares/sec), and the voltages are calibrated so that 1 mV = 10 mm (2 large squares) in the vertical axis. Therefore, each small 1-mm square represents 0.04 sec ... WebIntroduction to ECG Learn the Heart - Healio downpatrick post office sorting office
