QRS wave is a ECG wave generated by ventricular excitation, typically in a three-phase waveform, named qRs wave. The QRS waveform of each lead is different.

Holter Monitor
Real tape with the cardiogram of man. Image of Electrocardiogram close-up.
Bidirectional ventricular tachycardia is a kind of malignant arrhythmia. The polarity of QRS main wave alternates from beat to beat, and it is easy to degenerate into ventricular fibrillation.
R wave greater than S wave is judged to be positive; R smaller than S is judged to be negative; R equal to S amplitude is judged to be equipotential.
The illustration shows the two patterns of ventricular tachycardia episodes.The green circle represents sinus rhythm. Picture A shows paroxysmal episodes of ventricular tachycardia, and picture B shows short bursts.
Intensive care unit.
The QT interval of ECG is from the beginning of QRS wave to the end of T wave, representing the total time of ventricular depolarization and repolarization.

Electrocardiogram
When the left free wall and septal accessory pathway are excited, preexcitation waves with different polarities are generated in leads and aVL.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
When the rhythm of the atria originates in the lower part of the atria, the whole atria are excited from inferior to superior, producing negative P waves in the inferior leads.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
When the left anterior wall and posterior wall accessory pathway are excited, preexcitation waves with different polarities are generated in the inferior wall leads of , and aVF.
ECG displaying the chaotic rhythm of ventricular fibrillation, a life-threatening cardiac arrhythmia, 3D illustration.
Male, 71 years old, was clinically diagnosed with upper gastrointestinal bleeding. During sleep at night, ECG monitoring showed sinus bradycardia, blood pressure 115 and 70mmHg.
ECG in atrial flutter, an abnormal heart rhythm characterized by rapid, regular contractions of the atria. 3D illustration displaying characteristic sawtooth P-waves and irregular ventricular rhythm.
Asystole, a critical condition marked by the absence of any cardiac electrical activity. 3D illustration shows a flatline on the ECG, signifying a nonfunctioning heart with no pulse or heartbeat.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
When there is a left ventricular free wall bypass, the polarity of the ventricular preexcitation is positive in lead V1 and negative in lead aVL on the electrocardiogram.
Surrounding the atrioventricular ring, except for the anterior septum of the left ventricle, there is no distribution of accessory pathways, and accessory pathways can exist in other parts.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.

On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
Female, 85 years old, was admitted to the hospital after 20 minutes of sudden unconsciousness. The admission ECG indicated electrical mechanical disassociation, which is a type of cardiac arrest.
