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.
Atrial focal originating in the left upper pulmonary vein, with an upright P wave in V1 and wide duration, inverted P wave in lead aVL and an upright P wave with notch in inferior leads.
When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
The PR interval is age-related, and the PR interval should be assessed for abnormalities based on the age of the person being examined.
When the amplitude of the T wave exceeds 5 mm in the limb leads and 10 mm in the thoracic leads, it is called high T wave.High T waves can be seen in physiological and pathological conditions.
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.
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.
The typical ST-T changing of left ventricular hypertrophy are: ST segment slightly convex with downward sloping depression; fusion of ST segment and inverted T wave; asymmetry of inverted T wave.
Male, 65 years old, was clinically diagnosed with acute anterior myocardial infarction. The patient was treated with a coronary stent, but no reperfusion T wave occurred on day 2.
A patient with AIMI presents with a sudden widening of the QRS complex in the junctional escape rhythm, premature ventricular contractions, resulting in polymorphic ventricular tachycardia.
The effective refractory period of the ventricular muscle is equivalent to the time from the onset of QRS to the peak of the T wave on the ECG.
The presence of atrioventricular dissociation in wide-complex tachycardia is highly suggestive of ventricular tachycardia.
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.

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.
In acute left main occlusion, the left ventricular myocardium is massively ischemic and necrotic, the excitatory potential of the left ventricle is weakened, and the axis may deviate to the right .
Because of the slow conduction of atrioventricular node, the PR interval of adult ECG should be greater than 120ms. This physiological phenomenon is called atrioventricular delay.
A patient with AIMI presents with a sudden widening of the QRS complex in the junctional escape rhythm, premature ventricular contractions, resulting in polymorphic ventricular tachycardia.
Early repolarization is a common benign ECG change that manifests as J-point ECG with or without ST-segment elevation.
The PR interval of an ecg includes the time during which supraventricular impulses are transmitted through the atrioventricular node, His bundle, bundle branches, and terminal Purkinje fibers.
Drawing ECG
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.
Cardiologist examining senior patient with Holter device in the department of cardiology in the hospital. Woman doctor attaches sensors to measure ECG and blood pressure. Matury man on clinic couch
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.
During nocturnal sleep, vagus tone is elevated, and ECG may show both sinus bradycardia and first-degree atrioventricular block.
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.

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.
In patients with emphysema, the anatomical position of the heart is more vertical, the depolarization potential of the right atrium from top to bottom increases, and the P wave of the ECG increases.
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.
The atrioventricular junction area includes the lower part of the atrium, atrioventricular node, and His bundle, and is a necessary pathway for electrical impulses to travel from the atrium to the ventricle.
The presence of ST-segment prolongation and T wave symmetry and high tip on ECG suggests hypocalcemia and hyperkalemia.
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.
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.
