Electrocardiography

Electrocardiography is the process of producing an electrocardiogram, a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle. Changes in the normal ECG pattern occur in numerous cardiac abnormalit…

tracing by three basic waveforms: the P wave, the QRS complex, and the T wave. A U wave is sometimes present. Between the waveforms are the following segments and intervals: the PR interval, the PR segment, the ST segment, and the QT interval.

What are P waves in the heart?

  • With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when...

What is cardiac flow?

  • Cardiac output is blood flow. Specifically, it's the blood flow through the heart, which is pumping blood to the lungs (right side of the heart), and to the rest of the body (left side of the heart). Obviously all three of these "flows" - transcardiac, transpulmonary and trans-rest-of-the-body - must be equal.

What is a heart P wave?

  • The P wave, QRS complex and the T wave represent electrical activity in the heart on an electrocardiogram. The ECG Learning Center explains that the P wave represents the depolarization of the right and left atria. The QRS complex follows the P wave and depicts the activation of the right and left ventricles.

The arterial waveform is measured continuously in many operating rooms and intensive care units, and obtaining the arterial pressure waveform can be accomplished by simple catheterization and even noninvasively. The bene!t is the continuous measurement of arterial pressure with decreased risk to the patient.
