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.
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.
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.
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.

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.

Einthoven triangle assumes that the left upper limb, right upper limb and left lower limb form an equilateral triangle, and the heart is located at the center of the triangle.

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.

Early afterdepolarization is an arrhythmogenic mechanism that triggers activity, occurring before the end of the T wave and commonly seen in QT interval prolongation.
When the R wave amplitude of lead V1 in adults exceeds 6mm and there are no organic heart disease or other disease electrocardiogram changes, it is a simple right ventricular high voltage.
