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.
Ventricular tachyarrhythmia includes many clinical types, some benign and some malignant. For malignant ventricular arrhythmias, patients are at risk of death.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
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.
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.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
Normal electrocardiogram of a 34 year old Chinese healthy woman.The rhythm was sinus rhythm without other abnormal ECG changes.
Male, 70 years old, hospitalized due to chest pain for 30 minutes. Coronary angiography confirmed that the proximal segment of the LAD was subtotal occluded, LCX was narrow 70%, and RCA was normal.
The presence of ST-segment prolongation and T wave symmetry and high tip on ECG suggests hypocalcemia and hyperkalemia.
The presence of atrioventricular dissociation in wide-complex tachycardia is highly suggestive of ventricular tachycardia.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
Mitral stenosis is a common valvular heart disease, the disease develops to a certain period, the most common arrhythmia is atrial fibrillation, combined with right ventricular hypertrophy.
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.
Ventricular tachycardia originating from the right ventricular outflow tract can be sustained or short-burst, and is a benign idiopathic ventricular tachycardia.
A normal ECG is an ECG that does not have any abnormal changes and can be seen in healthy people as well as in people with heart disease.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
The presence of atrioventricular dissociation in wide-complex tachycardia is highly suggestive of ventricular tachycardia.
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.
Female, 76 years old, ECG collected during the onset of chest pain.Wellens syndrome combined with left septal fascicular block.
The transverse vectorcardiogram generates a chest leads electrocardiogram, with the maximum ventricular excitation potential oriented towards the left posterior region.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
A normal ECG is an ECG that does not have any abnormal changes and can be seen in healthy people as well as in people with heart disease.
Poor R wave progression can be seen not only in acute coronary syndrome, but also in non ischemic heart disease, which is easily misdiagnosed as myocardial infarction.
Sometimes, coarse atrial fibrillation is easily misdiagnosed as atrial flutter, but their shape, amplitude and frequency are almost beat by beat changes.
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.
Male, 58 years old, clinically diagnosed as COPD. Paroxysmal atrial flutter and atrial fibrillation were found by ambulatory electrocardiogram.
Sometimes, coarse atrial fibrillation is easily misdiagnosed as atrial flutter, but their shape, amplitude and frequency are almost beat by beat changes.
When ventricular hypertrophy occurs, the amplitude of the S-wave in each lead will change, which is a clue for electrocardiogram diagnosis of ventricular hypertrophy.
Sometimes, coarse atrial fibrillation is easily misdiagnosed as atrial flutter, but their shape, amplitude and frequency are almost beat by beat changes.
Sometimes, coarse atrial fibrillation is easily misdiagnosed as atrial flutter, but their shape, amplitude and frequency are almost beat by beat changes.
Female, 27 years old, clinically diagnosed as uremia for 5 years, received dialysis treatment.Chest lead QRS wave showed low voltage.
Male, 58 years old, clinically diagnosed as COPD. Paroxysmal atrial flutter and atrial fibrillation were found by ambulatory electrocardiogram.
When measuring the cardiac cycle, select leads with stable ECG waveform and choose ECG waves from the same location as the measurement reference point.
Sometimes, coarse atrial fibrillation is easily misdiagnosed as atrial flutter, but their shape, amplitude and frequency are almost beat by beat changes.
If atrioventricular dissociation can be observed during wide QRS wave tachycardia, it can help diagnose ventricular tachycardia.
A is idiopathic right ventricular outflow tract ventricular tachycardia, and B is arrhythmogenic right ventricular cardiomyopathy.The former is benign, while the latter is malignant.
A normal ECG is an ECG that does not have any abnormal changes and can be seen in healthy people as well as in people with heart disease.
If the electrocardiogram during the onset of ventricular tachycardia cannot be recorded, it is possible to incorrectly analyze the QRS waveform based on the QRS waveform during the attack.
Under normal circumstances, notch T waves are more common in leads V2-V3 and are caused by asynchronous local ventricular repolarization.
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.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract is a benign ventricular tachycardia. This ECG shows a short burst pattern of ventricular tachycardia.
Under normal circumstances, in the chest lead electrocardiogram, the amplitude of the R wave gradually increases from lead V1 to lead V6.
