The start of the QT interval is the first deviation from the isoelectric line following the p wave and the end is the last time the waveform crosses the isoelectric line before the T-wave begins. The waveform may well corss the isolelectric line several times before the end of the QRS interval. Normal measurement is less than or equal to .12
In simple terms, it is the start and end of the "spiky" high-frequency part of the waveform.

What does the normal QRS complex measure?
does a normal qrs complex measures <.12
What is difference between QRS duration and QRS interval?
Nothing, they are equivalent.
What does QRS complex represents?
The ventricles contracting.
When does a QRS complex occurs?
When ventricles depolarize
What is QRS in ECG?
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
Complex that occurs as a result of depolarization of the ventricles?
QRS
How is ventricular systole indicated on an EKG?
QRS complex
What is an electrocardiogram's QRS pattern?
QRS-- A pattern seen in an electrocardiogram that indicates the pulses in a heart beat and their duration. Variations from a normal QRS pattern indicate heart disease.
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 qrs complex corresponds to depolarization of the muscle fibers of the?
the ventricles.
What does it mean when pacemaker spikes after qrs complex?
Atrial paced
What causes QRS complex to reverse?
left ventricular contraction
