A deflection is only referred to as a wave if it passes the baseline. If the first wave is negative then it is referred to as Q-wave. If the first wave is not negative, then the QRS complex does not possess a Q-wave, regardless of the appearance of the QRS complex. All positive waves are referred to as R-waves. The first positive wave is simply an “R-wave” (R).

Hence, ECG leads with net positive QRS complexes will show ST segment depressions (as well as T-wave changes). ECG changes in myocardial ischemia are discussed in section 3 (Acute & Chronic Myocardial Ischemia & Infarction) and a specific chapter discusses ST depression. ST segment elevation. ST segment elevation is measured in the J-point.

Top best answers to the question «What does qrs wave represent» Answered by Belle Keeling on Sat, Apr 10, 2021 10:58 AM. A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.

QRS Complex: The next area you see is a big spike. This spike is called the QRS complex. The bundle of His, bundle branches, and Purkinje fibers are responsible for this. Study tip: The QRS complex represent VENTRICLE DEPOLARIZATION (contractions of the ventricles) T-wave: After this spike, you will see a “bump” shortly after the complex. This “bump” is called the t-wave and …
QRS Interval • LITFL • ECG Library Basics
https://litfl.com/qrs-interval-ecg-library/
The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < 100 ms) are supraventricular in origin. Broad complexes (QRS > 100 ms) may be either ventricular in origin, or due to aberrant conduction of supraventricular complexes (e.g. due to bundle branch block, hyperkalaemia or …
