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.
Relative bradycardia refers to a pathophysiological phenomenon in which the patient's body temperature rises, but the pulse does not increase, which is common in some infectious diseases and jaundice.
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.
The 4-phase membrane potential of sinoatrial node pacing exhibits spontaneous depolarization, while the 4-phase membrane potential of ventricular myocytes remains stable.

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.
In humans, Purkinje fibers are not distributed throughout the entire ventricular wall, but rather in the superficial myocardium beneath the endocardium and do not reach the epicardium.
When emphysema occurs, the diaphragm moves downwards, pulling the right atrium, causing an increase in the longitudinal longitude of the right atrium, and an increase in the amplitude of the sinus P wave.
When the sinus P wave on the ecg disappears, it may be due to abnormal generation and/or conduction of sinus impulses, or it may be due to atrial muscle lesions that cannot excite.
QRS wave is a ECG wave generated by ventricular excitation, typically in a three-phase waveform, named qRs wave. The QRS waveform of each lead is different.
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.
Idiopathic ventricular tachycardia originating from the right ventricular outflow tract forms a high amplitude R wave in the inferior leads and a QS wave or rS wave in the V1 lead.

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.
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.
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.
QRS wave is a ECG wave generated by ventricular excitation, typically in a three-phase waveform, named qRs wave. The QRS waveform of each lead is different.
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.
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.
On the electrocardiogram, the range of the myocardium is explored based on the leads, and some leads are grouped according to myocardial anatomy to form anatomically contiguous leads.
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.
Ventricular tachycardia originating from the right ventricular outflow tract can be sustained or short-burst, and is a benign idiopathic ventricular tachycardia.
