What are the components of ECG?

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.

Keeping this in view, what does each waveform component represent?

Normal EKG tracings consist of waveform components that indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U. The following descriptions are with respect to Lead II. P wave is the first deflection and is normally a positive (upward) waveform.

Similarly, what does each wave of an ECG measure? An electrocardiogram — abbreviated as EKG or ECGis a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers.

Similarly, it is asked, what does the P QRS and T wave represent?

Atrial and ventricular depolarization and repolarization are represented on the ECG as a series of waves: the P wave followed by the QRS complex and the T wave. The first deflection is the P wave associated with right and left atrial depolarization. The second wave is the QRS complex.

What is the procedure of ECG?

An ECG is a noninvasive, painless test with quick results. During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes your limbs. These sensors are usually left on for just a few minutes.
