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.

What is QRS in ECG?
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
Why are ECG and pulse rates similar?
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.
What the meaning of suspected right hypertrophy low QRS amplitude probably abnormal ECG?
probably abnormal ECG?
Which phase of the ECG indicates ventricular excitation and contraction?
The QRS complex
In a normal ECG tracing?
the repolarization of the atria is hidden by the QRS wave
In a normal ECG trace, what does a QRS wave indicate?
the contraction of the ventricles
How do you tell a paced wave form on an ecg?
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.
What portion of the ECG indicates ventricular repolarization?
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
Why is the T wave positive in the ECG?
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
What part of an ECG represents ventricular depolarization?
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
The portion of the ECG tracing between the QRS complex and the T wave is called the?
ST segment
How does hyperkalemia relate to the ECG?
Hyperkalemia cause tall t wave and wide qrs wave
