WebThe P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node (where the conduction velocity is retarded) and the bundle of His. WebJul 2, 2024 · In general EKG’s are positive when a wave of depolarization is traveling toward the lead and negative when it is traveling away. So in a normal EKG you will see a biphasic or roughly equal positive and negative QRS in lead I because it’s perpendicular to the path the wave of depolarization is taking. ...

WebJul 23, 2024 · It appears as three closely related waves on the ECG (the Q, R and S wave). ST segment. The ST segment starts at the end of the S wave and ends at the beginning of the T wave. The ST segment is an isoelectric line that represents the time between depolarisation and repolarisation of the ventricles (i.e. ventricular contraction). T wave WebSep 17, 2024 · RS: tall R wave followed by a deep S wave, with similar amplitude (biphasic QRS). It is the characteristic morphology in lead sV3. Which is the first positive wave in the QRS complex? All positive waves are referred to as R-waves. The first positive wave is simply an “R-wave” (R). The second positive wave is called “R-prime wave” (R’).
