Drawing ECG graph with heart
Female, 51 years old, diagnosed with mitral stenosis. When this ECG was taken, the patient still maintained sinus rhythm.Note that the P wave duration was widened.
A 36 year old man survived CPR after sudden syncope. The electrocardiogram was suggestive of Brugada syndrome type 1. Implantation of ICD therapy.
When the left free wall and septal accessory pathway are excited, preexcitation waves with different polarities are generated in leads  and aVL.
ECG and heart
Male, 84 years old, admitted to hospital with chest pain for 1 day. ECG showed acute inferior and posterior MI and possibly right MI. The patient died of ventricular fibrillation the next day.
Ventricular tachyarrhythmia includes many clinical types, some benign and some malignant. For malignant ventricular arrhythmias, patients are at risk of death.

A 4-year-old boy with a clinical diagnosis of long QT syndrome. No genetic testing was done during hospitalization. The child died suddenly during follow-up.
Presentation of ECG graph
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.
Male, 60 years old, clinically diagnosed as acute extensive anterior wall myocardial infarction. The patient died of ventricular fibrillation after admission.
At present, there is a younger trend in patients with acute myocardial infarction, so it is important to check the ECG for acute chest pain in young people.
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.
Male, 84 years old, admitted to hospital with chest pain for 1 day. These ECG rhythms are the Holter monitor records of the patients after admission, and they are third degree atrioventricular block.

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.

Electromechanical separation is a kind of terminal ECG. The patient's ECG has electrical signals, the ECG wave is widened with morphological abnormalities, and the ventricle has no contraction.
Torsade de pointes refers to the pleomorphic ventricular tachycardia that occurs in the background of long QT interval, and the polarity of QRS wave twists around the equipotential line.
When the ventricular preexcitation wave leaves the baseline and then falls back to the baseline, it is interpreted as an isoelectric line preexcitation wave.
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 graph with heart
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.
A patient with acute extensive anterior  myocardial infarction developed ventricular tachycardia during hospitalization and quickly experienced cardiac arrest.
Ventricular preexcitation is the pre excitation of a portion of the ventricular muscle by the accessory pathway, forming a rough and dull, and fuzzy  wave that can be positive, negative, or biphasic.
Ventricular preexcitation is a fusion wave formed by the accessory pathway and normal atrioventricular conduction system exciting a part of ventricle respectively.
ECG graph with heart
During the onset of variant angina pectoris, ECG is divided into non fusion wave, partial fusion wave and complete fusion wave according to the fusion degree of QRS wave, ST segment and T wave.
In complete left bundle branch block, the conduction of the LBB can be completely interrupted or can still be conducted, but it is delayed by at least 45ms than the RBB.
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.
Note that the V3 lead of this ECG shows that the amplitude of R wave is greater than the amplitude of S wave, and there is counterclockwise rotation.
Coronary artery spasm causes transmural myocardial ischemia, and ST segment elevation in ECG has localization characteristics. Criminal vessels can be derived from ST segment elevation leads in ECG.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When ventricular preexcitation components occupy different proportions of QRS waves, the measured PJ intervals are different.
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.
Danger sign on the patient's ECG, close-up
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.
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.
 The polarity of ventricular preexcitation waves can be positive, as shown in Figures A and B, or negative, as shown in Figures C and D.
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.
Drawing ECG
Male, 13 years old, clinically diagnosed with secundum atrial septal defect. Note that the QRS wave in lead V1 of the electrocardiogram has a qR shape, indicating right ventricular hypertrophy.
Third degree atrioventricular block in young women may be congenital, with the block located on the atrioventricular node or above bifurcation of the His bundle.
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.
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.
