Who can explain to me the room speed, room speed, and room speed? EKG for ventricular tachycardia?

Xiao Lin, what are you talking about today? Premature sexual intercourse, some people ask, is it because of too much sex? It is caused by the incoordination of husband and wife life. In fact, it is not. Listen to me and tell you slowly. A normal heart beats regularly, and the intervals between heartbeats are basically equal. If a heartbeat suddenly occurs in advance, it is medically called premature beat (premature beat), or extrasystoles. During premature beats, the patient will feel palpitations, chest tightness, etc. But there are also patients who don't feel any discomfort. Early beats or "missed beats" may occur when the pulse is missed. Premature beats are very common and can occur on the basis of various heart diseases, but they can also occur in normal people. Don't be too nervous when premature beats occur. You should ask a doctor to find out the cause and decide whether and what medicine is needed. The prognosis of most patients with premature beats is good. Premature beat is the abbreviation of premature beat. Premature beats are also called extrasystoles, or premature contractions. The normal heartbeat range for adults is between 60 and 100 beats per minute. Taking a heartbeat of 72 times per minute as an example, the heart beats once every 0.83 seconds. If a person whose heart beats 72 times per minute suddenly has a beat that occurs prematurely in less than 0.83 seconds during a uniform heartbeat, it is called a premature beat. Premature beats are the most common heart rhythm disorder. Among normal people, if electrocardiogram is used for 24 hours of continuous observation, the number of premature beats may be recorded in 70 to 80% of people. It can be seen that premature beats are also very common in normal people. But most people have no symptoms of discomfort, or just feel their heart fluttering, or beating heavily, or their heart twisting. Frequent premature beats often cause people to feel palpitations, chest tightness, fatigue and other discomforts. Frequent premature beats may even cause angina pectoris or heart failure if there is a serious heart disease. Although premature beats are irregular beatings of the heart, not all premature beats are caused by disease. Emotional stress, excitement, anxiety, excessive smoking, large amounts of alcohol, strong tea, and even constipation can cause premature beats. Patients with non-cardiac diseases such as hyperthyroidism, anemia, hypokalemia, fever, etc. may also experience premature beats. Of course, various heart diseases can cause premature beats, but premature beats are more common in heart diseases such as rheumatic heart disease, coronary heart disease, myocarditis, and cardiomyopathy. Premature beats are caused by excessive excitability in a certain part of the heart. If there is a premature beat in the atrium caused by excessive excitability, it is called atrial premature beat; if it is caused by a higher excitement point in the atrioventricular node or the ventricle, Premature contractions are called atrioventricular nodal or premature ventricular contractions. It can be distinguished by an electrocardiogram. According to the frequency of premature beats, if it occurs more than 6 times per minute, it is called frequent premature beats, and if it occurs less than 6 times, it is called sporadic premature beats. If premature beats occur in pairs, it is called bigemy; if three premature beats occur in groups of three, it is called triponym. Occasional premature beats have little impact on blood circulation, especially if they are not caused by disease. As long as the causes of premature beats are removed, premature beats can be gradually eliminated. For premature beats caused by disease, the disease that induces premature beats should be cured first. Frequent premature beats, especially those based on heart disease, may evolve into serious heart rhythm disorders, or may lead to angina pectoris and heart failure, and attention should be paid to treatment. There are many drugs that can relieve premature beats, such as propranolol, vertapamil, bradycardia, amiodarone, quinidine, procainamide, etc. These drugs have many serious properties and should be taken under the guidance of a physician. , treatment should be patient and do not change dressings frequently. After premature beats are controlled, a small amount of medication is still needed to maintain the condition to avoid recurrence. Key points for self-observation (1) There may be no symptoms. ? (2) Occasionally, there is a feeling of palpitations or heartbeat pause. (3) When frequent premature beats reduce cardiac blood output, they can cause fatigue, palpitations, dizziness, chest tightness, and aggravate the original symptoms of angina pectoris or heart failure. Prescription 1. Premature beats themselves are not a serious disease, so patients should eliminate their worries, stay optimistic, and actively cooperate with treatment. 2. Pay attention to the balance between work and rest and get enough sleep. 3． Don’t smoke, don’t drink, don’t eat too much, and eat less spicy food. 4. Chronic patients whose premature beats do not increase after activity should participate in cultural and sports activities appropriately. 5. People with severe heart disease or obvious symptoms must take antiarrhythmic drugs. Such drugs should be taken under the guidance of a physician.

Note: Occasional premature beats, especially in healthy normal people, do not affect the ventricular blood output function and do not require treatment or downtime. The prognosis is good. People should be highly vigilant when acute myocardial infarction occurs and frequent ventricular premature beats may develop into ventricular tachycardia or ventricular fibrillation, and the prognosis is poor. For those with frequent premature beats and obvious symptoms, the cause should be identified promptly and actively treated. Especially for premature beats from multiple sources, antiarrhythmic drugs should be promptly applied to control them. Frequent or multiple sources of premature atrial or ventricular contractions in patients with structural heart disease may develop into atrial tachycardia, atrial fibrillation, ventricular tachycardia or ventricular fibrillation, if not treated in time, which may be serious. Threatening life.
