What is the difference between left and right heart function, and how does left and right heart func

Left-sided ventricular insufficiency is common in hypertension, coronary heart disease, cardiomyopathy, mitral regurgitation, etc. It is mainly due to left ventricular damage or overload, resulting in pulsation dysfunction and decreased cardiac output, resulting in pulmonary congestion and even pulmonary edema. The main manifestations are fatigue and fatigue, dyspnea, which begins with exertional dyspnea and eventually evolves into dyspnea at rest, and can only breathe upright.

Paroxysmal dyspnea is a typical manifestation of left-sided heart failure, more than the onset of deep sleep, chest tightness, shortness of breath, cough, wheezing, especially severe can evolve into acute pulmonary edema and manifest severe wheezing, orthopnea, extreme anxiety and coughing up foamy mucus sputum (typically pink foamy sputum), cyanosis and other pulmonary depression symptoms.

Right-sided heart insufficiency is common in pulmonary hypertension, cor pulmonale, mitral stenosis, chronic obstructive pulmonary disease, etc., and is often secondary to left-sided heart failure. It is mainly due to the dysfunction of the right ventricular pulsation and the decrease in cardiac output, which leads to systemic congestion and increased venous pressure, and is often accompanied by lower extremity edema or even generalized edema. The main manifestations are edema of the lower limbs, jugular venous distension, loss of appetite, nausea and vomiting, oligouria, nocturia, and separation of drinking water and urination.

The cardinal signs are basal wet rales or panpulmonary wet rales, hypersecond tone of the pulmonary valve, gallop rhythm and alternating pulses, hepatomegaly, and positive hepatocervical regurgitation.

Left-sided heart failure is characterized by pulmonary congestion and decreased cardiac output. 1: Difficulty breathing:

The earliest symptoms are dyspnea on exertion, which is exacerbated by exercise. Pulmonary congestion reaches a certain level where the patient cannot lie flat. Sometimes people suddenly wake up from falling asleep with breath-holding, and they need to hold their breath to get better.

In acute pulmonary edema, the patient coughs up large amounts of pink, frothy sputum. There may also be symptoms such as fatigue, dizziness, and palpitation.

Right heart failure is predominantly manifested by systemic congestion. Gastrointestinal symptoms, which may include bloating, loss of appetite, nausea, and vomiting are the most common symptoms of right-sided heart failure.

Jugular venous distension is the cardinal sign. Liver distension and tenderness in the liver area.

The left side (left heart) carries red blood (arterial blood) containing oxygen from the lungs to all parts of the body, and the right side pump (right heart) carries black blood containing carbon dioxide (venous blood) collected from the whole body to the lungs.

Left atrium, left ventricle.

It's the arterial heart. Left atrium acceptance.

Pulmonary veins. Arterial blood and its passage to the left ventricle, which carries the received arterial blood into the right atrium and right ventricle of the aorta.

It's a venous heart. The right atrium houses the superior and inferior vena cava.

Venous blood and its passage to the right ventricle, which sends the received venous blood into the pulmonary artery.

Not metaphorically, these are two defining words.

Left ventricle, right ventricle are both human organs, medical term. Not figuratively.

It's not a metaphor, it's that there really is a left ventricle and a right ventricle in the heart, and both are indispensable.

A normal heart with its left ventricular muscles must be able to

1.Relaxation and filling of the diastolic phase is achieved by relaxing and releasing the diastolic blood from the pulmonary veins to allow the oxygenated blood from the pulmonary veins to fill up quickly.

2.Rapid and intense contraction pushes a large amount of blood into the aorta, overcoming very high aortic pressure and providing additional pressure to extend the aortic and other major arteries and provide sufficient space for a sudden rise in blood volume, i.e., systolic contraction and efflux of the heart.

3.Under the control of the central system, its pumping capacity is increased or decreased instantaneously.
