In a normal ECG trace, what does a QRS wave indicate?
the contraction of the ventricles
Give an example of the other type of wave.?
The PR wave,QRS wave, and T wave.
What is QRS in ECG?
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
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.
How does hyperkalemia relate to the ECG?
Hyperkalemia cause tall t wave and wide qrs wave
What happens immediately after the QRS wave of the cardiac cycle?
There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.
The period during which the ventricles are depolarizing which precedes their contraction?
QRS wave
In a normal ECG tracing?
the repolarization of the atria is hidden by the QRS wave
What does a segment of an ECG tracing indicate?
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
What is it called when there are no QRS waves following p waves?
The QRS complex and the P wave are features of the electrocardiogram, which graphically displays the electrical activity of the heart. The P wave is generated when the atria, or upper chambers of the heart contract. The QRS complex is generated when the ventricles or lower chambers of the heart contract. If there is a P wave but no QRS, the the heart's main pump is not functioning. This would cause death quickly.
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
Which part of the QRS complex represents the repolarization of the atria?
Which part of the QRS complex represents the repolarization of the atria?A.The Q waveB.The R waveC.The S waveD.None of the aboveThe S wave
