Male, 23 years old, healthy. When the initial excitation potential of the ventricle deviates from a certain lead axis, a Q wave will be projected onto that lead, which is a physiological Q wave.
When intermittent conduction dysfunction occurs in the Bachmann bundle, intermittent left atrial abnormality may be seen on the ECG, which can be differentiated from anatomical left atrial enlargement.
In the aVR lead, the QRS wave can be in the form of QS, rS, Qr, rsr, etc., with the main wave being negative.
Second degree rinteratrial block includes two types: type 1 block with progressive worsening of conduction and interruption of conduction, and type 2 block with fixed conduction and interruption.
Third degree block refers to persistent or permanent interruption of conduction, which can occur in any part of the conduction system and produce corresponding electrocardiogram changes.
Under normal circumstances, when the initial excitation potential of the ventricle is far away from a certain lead axis, a Q wave will be projected on that lead, which is a physiological Q wave.
In the aVR lead, the QRS wave can have an initial r wave or no initial r wave, depending on whether the initial excitation is directed upwards or downwards.
In the frontal plane lead system, when the maximum QRS wave potential is more parallel to a certain lead, the R wave amplitude of that lead is highest in the limb lead.
ECG displaying the chaotic rhythm of ventricular fibrillation, a life-threatening cardiac arrhythmia, 3D illustration.
A 3D scientific illustration depicting an electrocardiogram ECG displaying the chaotic rhythm of ventricular fibrillation, a life-threatening cardiac arrhythmia.
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.
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.
In the conventional 12 lead ECG, the chest lead system represents the electrical activity in the transverse or horizontal plane, and there are 6 traditional leads.
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.

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 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.
