a group of waves depicted on an electrocardiogram; it actually consists of three distinct waves created by the passage of the cardiac electrical impulse through the ventricles and occurs at the beginning of each contraction of the ventricles. In a normal electrocardiogram the R wave is the most prominent of the three; the Q and S waves may be extremely weak and sometimes are absent.

QRS mean "what do you want?" in Spanish so therefore it means "¿Qué quieres?"
QRS denotes depolarization of the ventricles.

The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
both are telling you how often the heart is beating. an ecg simply gives you more information. the spike on an ecg (qrs complex) is the heart contracting an refilling. when you take a pulse, you're feeling the heart beat blood.
probably abnormal ECG?
the contraction of the ventricles
The QRS complex
the repolarization of the atria is hidden by the QRS wave
in paced hearts, the ecg shows a sharp spike just before the qRs or R wave and the R wave will usually be widened if the ventricle is being stimulated directly. Similar to the appearance of the R wave in patients with complete heart block.
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
Hyperkalemia cause tall t wave and wide qrs wave
ST segment
