- QRS complex - Wikipedia
The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG) It is usually the central and most visually obvious part of the tracing
- The QRS complex: ECG features of the Q-wave, R-wave, S-wave duration
A detailed view of the QRS complex (Q-wave, R-wave and S-wave) with emphasis on normal findings, amplitudes, durations intervals, pathology
- QRS Complex - ECG
Explore the QRS complex in limb and precordial leads, its nomenclature, width, amplitude, and fragmentation Understand narrow, wide, and electrical QRS alternans
- QRS Interval • LITFL • ECG Library Basics
Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects) 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
- What Does the QRS Complex Represent in ECG - QRS Complex | Learn the Heart
What is QRS in ECG? The QRS complex in an electrocardiogram (ECG) represents the electrical impulses that trigger the heart's ventricles to contract and pump blood to the rest of the body It’s made up of three distinct waves: the Q-wave, R-wave, and S-wave
- ECG QRS Complex: What It Is and Why It Matters
The QRS complex represents the electrical activation, or depolarization, of the heart’s ventricles This electrical event immediately precedes the contraction of the large ventricular muscles, which are responsible for pumping blood to the lungs and the rest of the body
- QRS - EKG Lesson #301
Because of the larger tissue mass, the QRS complex is larger than the P wave While the prototypical QRS complex consists of three wave components, one or two of these components may be missing

QRS Complex: The QRS complex is the ventricular contraction (systole) consisting of the Q wave, which is the first negative deviation, followed by the R wave, a positive (upward) deviation
