Anemic Hypoxia, hypoxic, stagnant, histotoxic, arterial pO2 and O2, arterio-venous shunts, Respiratory system, 3d render
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.
Heart disease awareness and cardiovascular illness research and stroke prevention as a medical health symbol for high blood pressure hypertension and Arrhythmia with 3D illustration elements
The illustration shows the two patterns of ventricular tachycardia episodes.The green circle represents sinus rhythm. Picture A shows paroxysmal episodes of ventricular tachycardia, and picture B shows short bursts.

Viral myocarditis or virus infection of the human heart resulting in inflammation of the cardiac circulatory organ with 3D illustration elements.
Healthy Heart Food
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.

Male, 23 years old, healthy. When the initial excitation potential of the ventricle deviates from a certain lead axis, a Q wave will be projected onto that lead, which is a physiological Q wave.
The upper limit value of R wave amplitude in each lead of ECG is related to age, sex, body shape, etc. Here are the ECG data of Japanese adults.
Broken Heart Syndrome or Takotsubo cardiomyopathy with a healthy organ anatomy cross section concept of an inner cardiovascular organ with enlarged swollen chamber in a 3D illustration style.
Human Heart
After venous blood enters the pulmonary circulation, oxygenated blood returns to the left atrium and is pumped through the left ventricle into the aorta to complete systemic circulation.

Human Cardiovascular System
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.
Left Dominant Distribution of the Coronary Arteries
The classic pathological Q wave refers to a Q wave duration more than 40ms, with an amplitude greater than 25% R wave amplitude, commonly seen in cardiomyopathy and myocardial infarction.
The larger the left ventricular volume and the closer the distance between the left ventricular wall and the chest wall, the greater the amplitude of R wave in the left chest lead, and vice versa.
Human Blood Circulation Grunge
Hypertriglyceridemia is a common condition characterized by high levels of triglycerides in the bloodstream. 3D Render
Lipids are types of fat that travel through the bloodstream. 3D Render
Angiotensin receptor neprilysin inhibitors (ARNIs) are a combination medication that work by helping the kidney move extra sodium into the ureter, where it is flushed away with urine. 3D rendering

Human heart anatomy from a healthy body isolated on white background as a medical health care symbol of an inner cardiovascular organ in a 3D illustration style.
Human Heart Circulation
In the aVR lead, the QRS wave can be in the form of QS, rS, Qr, rsr, etc., with the main wave being negative.
Heart, Blood Supply (Anterior and Superior Surfaces)
Some measured values of ECG have differences in gender, age and race, for example, the QRS wave amplitude of Chinese is different from that of Caucasians.
Under the background of sinus rhythm, if the difference of P-P interval is less than 120ms, it can be considered that the rhythm is basically regular and can not be diagnosed as sinus arrhythmia.

Right Dominant Distribution of the Coronary Arteries
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.
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.
In the 12 lead ecg, the highest R wave amplitude is commonly found in the left chest lead, while the lead with the deepest S wave amplitude is commonly found in the right chest lead.
