The arrhythmias of the heart rhythm can be classified as pathological or functional due to the different causes of their onset. Pathological arrhythmias are a non-specific symptom of many organic heart diseases. The arrhythmia is accompanied by various clinical manifestations of the primary disease, such as coronary heart disease, cardiomyopathy, heart valve disease, medical|education.com collection of heart failure, etc. At present, it is believed that functional arrhythmia is related to autonomic dysfunction, which is also clinically dangerous and therefore should also be corrected. Functional arrhythmias are divided into slow and rapid. Slow arrhythmias that occur in a healthy population with an electrocardiogram or ambulatory electrocardiogram showing sinus bradycardia, significant sinus arrhythmia, intermittent sinus block, or atrioventricular block tend to occur in young people with high vagal tone. This condition mostly has no clinical symptoms or only mild chest tightness, and physical exercise can increase the heart rate and improve the symptoms, usually without drug treatment. Tachyarrhythmias can be manifested as intermittent or continuous episodes of atrial premature beats, ventricular premature beats and tachycardia with sinus or various ectopic pacing points, etc. The most common clinical ones are paroxysmal sinus tachycardia, supraventricular or ventricular tachycardia, and episodic atrial fibrillation. Electrocardiogram is the most basic test to diagnose arrhythmia. By recording the ECG during an attack, the basic type of arrhythmia can be initially determined. However, to understand the frequency and identify the nature of arrhythmia episodes, an ECG stress test is sometimes required. Functional arrhythmias tend to disappear or not worsen during exercise, while pathological arrhythmias can be worsened by exercise. For the diagnosis of arrhythmias, it is very important to do an ambulatory ECG. Ambulatory ECG is a continuous recording of 24-hour ECG, which is very effective in determining the nature of the arrhythmia, the site of origin of the ectopic beats, including monogenic and polygenic, the frequency of occurrence, and whether it is accompanied by myocardial ischemia. The treatment of patients with arrhythmias is not only based on symptoms but also depends on the determination of the cause of the disease. The first step should be to distinguish pathological or functional arrhythmias based on clinical and electrocardiographic examination. In pathological arrhythmias, organic disease should be excluded before treatment, because pathological arrhythmias caused by disease should first be treated with targeted treatment of the cause. In contrast, the treatment of functional arrhythmias is mainly to improve the autonomic functional state, including the adjustment of sympathetic tone. Among the many antiarrhythmic drugs, beta-blockers have a high degree of non-specific selectivity, can regulate the autonomic function state, reduce sympathetic tone, and have a moderating effect on lowering the heart rate. Functional arrhythmia is a reflection of autonomic imbalance, so it is suitable for β-blockers. β-blockers are a series of drugs, the dosage of each drug is not exactly the same, and there are great individual differences in the sensitivity of the population to them. To avoid unwanted adverse reactions, they should be taken under medical supervision, starting with small doses and gradually increasing them until the therapeutic goal is reached. Sometimes pathological and functional arrhythmias coexist and are mutually causative, and beta-blockers can slow down the heart rate, reduce myocardial oxygen consumption, and have a cardioprotective effect, and can still be the drug of choice. Chinese medicine has a unique role in the treatment of functional arrhythmias. Its theory is that arrhythmias and the accompanying systemic symptoms of autonomic dysfunction are palpitations caused by the imbalance of yin and yang in the body. Functional arrhythmias in young people tend to occur in groups with irregular lifestyle, poor dietary habits (overeating, chronic over-eating, excessive fatty and oily food), lack of exercise or chronic mental stress. The clinical manifestations are palpitations accompanied by irritability, insomnia and dreaminess, the ability to eat and drink, medical|education.com collects and organizes, or although the appetite is strong, but feel sleepy and weak, sluggish, physical incompetence. The treatment should be based on the specific situation, respectively, using the treatment of clearing heat and dispelling dampness, benefitting the qi and tranquilizing the mind, unblocking the liver and relieving depression, mostly with the application of warm gall bladder soup, plus flavor prodigy pill, sour date palm soup, er Chen Tang, San Ren Tang, Jiaotai pill and other additions. In the elderly population, it is mostly characterized by deficiency of both heart and spleen, heart and kidney yin deficiency, liver and kidney yin deficiency, or liver-depressed blood deficiency, spleen and kidney deficiency, and heart and kidney non-interaction, and is often seen in conjunction with actual symptoms such as liver-depression and damp-heat. Clinical symptoms include dizziness and tinnitus, blurred vision, lightheadedness, insomnia and forgetfulness, dullness and weakness, baking and sweating, irritability and irritability, or depression. It is advisable to take into account both the symptoms and the root cause, and to supplement the deficiencies and relieve the realities. We often use Jiaotai Pill, Sour Date Soup, Liu Wei Di Huang Pill, Gui Zhi Tang, Chai Hu plus Dragon Bone and Oyster Soup, and traditional Chinese medicine soup prescriptions with addition, reduction, and flexible application.
