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.
Due to the large mass of the left ventricle, the dominant excitation potentials of the left and right ventricles are oriented towards the left ventricle, i.e. towards the left, Inferior and posterior.
It is best to measure the QRS wave duration in a 12 lead synchronous electrocardiogram, as some of the QRS wave start and end points are located on the isoelectric line.
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.
A normal electrocardiogram includes normal morphology, amplitude, and various measurements of duration and interval, normal electrical axis, and normal R wave progression.
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.
In the frontal plane lead system, when the initial vector of the QRS wave is directed downward, the positive initial QRS wave is recorded in leads II, III, and aVF.
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.
QR code
The transverse vectorcardiogram generates a chest leads electrocardiogram, with the maximum ventricular excitation potential oriented towards the left posterior region.
When acute left main artery occlusion causes ST segment elevation myocardial infarction, it is often accompanied by extensive anterior and high lateral myocardial infarction.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.
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.

The 4-phase membrane potential of sinoatrial node pacing exhibits spontaneous depolarization, while the 4-phase membrane potential of ventricular myocytes remains stable.
On the conventional 12-lead ECG, under normal circumstances, there are some inherent patterns of QRS waves in different leads, which are not exactly the same.
In the spatial anatomy of the heart, the axis from the base of the heart to the apex of the heart is called the long axis, that is, the upper right side faces the lower left side.
The terminal excitation of the ventricle forms the final part of the S wave in lead V1, gradually returning to the isoelectric line, and forms a small S wave in lead V5.

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.
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.
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.
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.
When the first degree interatrial block occurs, the conduction time from the right atrium to the left atrium is prolonged, the P wave widens, and bimodal P wave ECG changes appear.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.

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.
When the frontal QRS axis is at +83, the R amplitude of lead aVF is the highest.The frontal QRS axis is almost perpendicular to the axis of lead .
Clockwise rotation electrocardiogram refers to the transition of the rS waveform of the chest lead to the left chest lead, with the transition lead exceeding the V4 lead.
Some patients with severe sinus bradycardia have triggers that can disappear after treatment, while others are permanent and require treatment with ventricular pacemakers.
Septal q wave loss refers to the initial q wave loss of leads I, aVL, V5, and V6, which can be partially or completely lost.
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.
