Always feel sick to the heart? This "Heart Health self-examination Handbook" can often be taken out and flipped through.
The various organs of the body also begin to appear degenerative diseases gradually, so what are the symptoms if the heart is not good? ●, the reason why I want to explain in detail the location of the heart and the shape of the great blood vessels of the heart, in prime time, if there is no medical staff nearby, chest compressions are done, because when the pumping function of the heart stops after cardiac arrest, then our brain and other important organs will be ischemic and anoxic. Normally, the heart shoots blood from the left ventricle into the aorta through its continuous contraction and relaxation. After metabolism in the tissue site, the blood flows back into the heart along the superior and inferior vena cava, and then the heart pumps venous blood into the lung tissue again through the right ventricle, and it also has the function of relaxing blood vessels, lowering blood pressure, and regulating the heart-- dilating the pulmonary arteries and bronchi. What are the common symptoms of a bad heart? For example, some patients with atrial fibrillation will have black spots when they have an attack, and some patients with premature beats will be restless.
Our human body is like a machine, with the growth of age, various organs of the body also begin to gradually appear degenerative diseases, each has its own clinical symptoms, such as bone spur on the foot, then walk on the pain is severe, take what medicine is not relieved, such as gingival atrophy, will slowly lose teeth, then if the heart is not good, what are the symptoms? What should we do about it? Please read on.
The position and function of the heart
●PositionThe heart is located in ourIntrathoracic cavityBetween the upper two lungs of the diaphragm, about 2/3 is on the left side of the midline. If you have taken a chest X-ray, the position of the heart is very obvious, and the heart is like an inverted front and back slightly flattened cone.Popularly speaking, like a peach.The obtuse circle of the heart tip is facing to the left anterior and inferior, adjacent to the anterior chest wall, and its body surface is projected at 0.5-1.0cm inside the middle line of the clavicle in the fifth intercostal space of the left anterior chest wall, so it can be seen or felt here.Apical beat. The heart base is wide, and there are large blood vessels in and out of this, facing to the right back and above, adjacent to the organs of the posterior mediastinum, such as the esophagus.
●, the reason why I want to explain in detail the location of the heart and the shape of the heart and blood vessels is actually related to the skills that everyone in society should learn, that is,cardiopulmonary resuscitation (CPR)If you do chest compressions without medical staff nearby during prime time, you will probably save someone else's life. I have seen many enthusiastic people perform chest compressions before the arrival of medical staff.But the pressing position is wrong, and some even press to the right chest.Here, I will popularize the science a little bit, and press the position inThe junction of the middle and lower 1 stroke of the sternumIt is the position of the heart. Some friends may not know why pressing this area can save lives, because when the heart pumping function stops after cardiac arrest, then our brain and other important organs will be ischemic and anoxic, so through exogenous compressions.Can serve as a temporary purpose of pumping blood.
●FunctionThe pumping function of the heart is the most important function of the heart. Normally, the heart shoots blood from the left ventricle into the aorta through its continuous contraction and relaxation.And promote the blood flow.To provide nutrients and oxygen to the brain and other parts of the brain to complete the body's metabolic needs, after metabolism in the tissue, the blood will flow back into the heart along the superior and inferior vena cava, and then the heart will again pass through the right ventricleVenous blood is pumped into lung tissueThe lung passes through the tissue exchange of capillaries, which makes the oxygen-rich arterial blood enter the heart and enter the circulation again.
● heart, it can also secreteNatriuretic peptide hormoneIt plays an important role in maintaining the balance of water and electrolytes and promoting the excretion of metabolites.Dilate blood vessels, lower blood pressure, regulate heart function-- dilating the pulmonary arteries and bronchi, increasing the active substances on the lung surface to improve ventilation and ventilation of the lungs, promoting fluid extravasation in capillaries and reducing the plasma volume of the whole body, careful people should find that many hospitalized patients with heart failure have to review an index repeatedly, that is,BNPBecause the index of patients with heart failure is often very high, hospitalization will gradually begin to decline after a period of treatment, so this test program is alsoGuide clinical treatment and prognosis evaluationThe important reference is.
What common symptoms does a bad heart have?
In fact, ●, this is very extensive, because heart disease is a general term, which contains many types of heart disease, which may be organic, functional, conductive, congenital, and so on, and various diseases will also have their own different clinical symptoms. I will give a general description below for reference only.
oneWhen arrhythmia occurs:Refers to the heartbeat is too fast, too slow, irregular, etc., there will bePalpitation, chest tightness, palpitations, shortness of breath, dizzinessAnd so on, for example, some patients with atrial fibrillation will still have blackness when they have an attack, that is, they will feel black and unstable, and some patients with premature beats will be restless, that is, they will feel uncomfortable in the precordial area.I can't describe how uncomfortable it is.Therefore, special attention should be paid to these symptoms.
twoWhen the heart pumping function is impaired:To put it bluntly, that is, the blood produced by the heart after each beat is not much normal, and if there is not enough blood in the peripheral organs, there will beDizziness, fatigue, reduced exercise endurance, decreased blood pressureAnd so on, if the heart failure, then the blood stasis, willEdema, shortness of breath, dyspnea, cough pink foamy sputum, can not lie flat at nightWait.
threeDuring myocardial ischemiaThis is actually the same as the blood supply vessels around the surface of the heart (coronary arteries) related, the most common is atherosclerosis, vascular stenosis, then myocardial blood supply insufficiency will have chest pain, if the pain will occur or aggravate after activity, as the degree of vascular stenosis is more serious, there may be rest.Angina attackIf it continues to develop, vascular occlusion, that is, myocardial infarction, there will be precordial area.Crushing pain.
fourFor congenital heart disease:In fact, there are many types, and the common symptoms areFrequent colds and recurrent respiratory infections, prone to pneumonia; poor growth and development, emaciation, sweating; inability to suck when feeding, difficulty in breast-feeding, or babies refuse to eat, cough, and shortness of breath; children complain that they are prone to fatigue and poor physical strength; lips and nails are blue or blue after crying or activity, clubbing toes; like squatting, there will beSyncope, hemoptysisWait for performance.
Common examination methods of heart disease
●ECG and 24-hour ambulatory electrocardiogramRoutinely speaking, we can look at the conduction of the heart, whether the heart rate is fast, arrhythmia, if it is irregular, then see if it is atrial fibrillation or premature beats, whether it is caused by atrium or ventricle.Preliminary screeningIf there is a problem such as ventricular extrasystole further work is neededDynamic ECGTo see if there are more premature beats in a day, which is also an important reference test to guide clinical treatment.
●EchocardiographyThe heart can be observed by B-ultrasoundShape, wall motion, cardiac valvular activity, and left ventricular function, EFHow much, whether there is congenital heart disease and so on.
●Treadmill exercise test:It can be used to observe the occurrence of heart rhythm during exercise and to judgeIs there a relationship between exercise and arrhythmiaAt the same time, it can also observe the blood supply of the heart to help diagnose coronary heart disease.
●Radioisotope cardiac dynamic function examinationIt is usually divided intoCardiovascular scintillation radiography, cardiac function isotope examination and myocardial isotope scanningIsotope cardiovascular scintigraphy can diagnose mitral stenosis or insufficiency, pericardial effusion, cardiomyopathy, left atrial myxoma, etc. Cardiac function examination is mainly ventricular ejection fraction. Diastolic and end-systolic volume, stroke volume, cardiac output, pulmonary blood volume, valvular regurgitation and coronary blood flow can be observed by isotope myocardial scanning.Reserve functionWait.
●Catheter and angiocardiographyIt is used for heart diseases which are difficult to be diagnosed by other diagnostic methods. At present, coronary angiography is the "gold standard" for the diagnosis of coronary atherosclerotic heart disease.The position, degree, or extent of narrowness.And provide a basis for treatment, and left ventriculography can be performed at the same time to evaluate cardiac function.
How to take care of the heart?
●Lifestyle:To combine work and rest, maintain emotional stability, avoid great joy and sorrow, do not disrupt the law of life, pay attention to work and rest time and control entertainment, avoid watching TV and playing cards for a long time, avoid long-term tiredness, staying up late, anxiety, excessive mental tension, avoid strenuous activities and so on.
●On dietPay attention to a low-salt, low-fat diet, limit the total salt intake to less than 6g every day, and eat more fresh melons, fruits and vegetables, because fresh melons and vegetables are rich in magnesium, potassium and folic acid, which can help prevent the progression of atherosclerosis and further improve the condition of hypertension. Regularly monitor heart rate, blood pressure, ECG, blood lipids, liver function, kidney function and heart color ultrasound examination, if there are the common manifestations I mentioned above, it is best to go to the regular hospital cardiology department for examination and treatment in time.
