Ventricular tachyarrhythmia includes many clinical types, some benign and some malignant. For malignant ventricular arrhythmias, patients are at risk of death.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS 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.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
Sometimes, there may be slight non-specific changes and normal variations in the electrocardiogram, which are often due to physiological reasons and have no clinical therapeutic significance.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
The high lateral  lead group includes leads I and aVL, used to explore the myocardium of the high lateralwall of the left ventricle.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS wave.
During ventricular depolarization, a spatial QRS loop is generated, projected onto the frontal lead system, forming the frontal QRS loop, which further forms the electrocardiogram.
In frontal lead system, when the average ventricular excitation potential is in the range of +60 degrees to+90 degrees, the QRS main wave of aVL lead is negative.
Male, 75 years old, clinically diagnosed as acute anterior septal and high lateral myocardial infarction.The culprit vessel was located in the LAD proximal segment.Prolonged QT interval with TDP.
The chest electrode of ECG includes conventional chest lead, posterior wall lead and right ventricular lead. The placement of chest lead electrode shall comply with the specification.

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.
In acute myocardial ischemia, the amplitude of T wave is increased first, and then the ST segment is elevated. When the end of QRS wave is deformed,  there is a lack of collateral circulation.
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.
In ST segment elevation myocardial infarction, the ST-T of ECG will undergo a characteristic evolution process, and finally appear pathological Q wave, sometimes lasting for a lifetime.
