Explain What the Different Ekg Waveforms Represent
The PR interval represents the atrial depolarization and physiological delay of the stimulus in the atrioventricular AV node. The QRS complex one single heart beat corresponds to the depolarization of the right and left ventricles lower heart chambers. P Wave Qrs Complex And T Wave Cardiac Physiology Nursing Notes Cardiac Nursing Cardiac Sonography The electrical impulse then reaches the ventricles. . The U-wave which is a positive wave after the T-wave appears occasionally on the ECG. Its normal value is between 012 s and 020 s. V4 5th intercostal space in the midclavicular line. Between the waveforms are the following segments and intervals. The P wave is the first positive deflection on the ECG. P Q R S T corresponding to different phases of the heart activities. The P-wave represents the depolarisation of the atria which leads to the contraction of both the atria. ECG interpretation traditionally start...
