What are the main electrical events recorded by an ekg? The electrical events of the heart are usually recorded on the ECG as a pattern of a baseline broken by a P wave, a QRS complex, and a T wave.
What does the EKG record? An ECG records these impulses to show how fast the heart is beating, the rhythm of the heart beats (steady or irregular), and the strength and timing of the electrical impulses as they move through the different parts of the heart.
What are the main parts of an EKG trace? There are three main components to an ECG: the P wave, which represents the depolarization of the atria; the QRS complex, which represents the depolarization of the ventricles; and the T wave, which represents the repolarization of the ventricles.
What do ECG electrodes detect? An electrocardiogram (ECG) is a simple test that can be used to check your heart’s rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats.
