I believe many people have experienced dizziness, fatigue, the immediate experience of blackening, resulting in learning can not use the work, can not work on the heart .This symptom appears, some people think it is 'too tired', I feel nothing to rest. However, if you look at the heartbeat at this time, you will find things are not so simple, there may be a problem with your heart.
Normal heartbeat to ensure the body's blood supply to various tissues and organs, if the heart rate is less than 60 beats / min, then known as bradycardia bradycardia will lead to decreased cardiac output, vital organs and tissues (especially the brain) insufficiency , Light affect life and work, severe cases lead to various arrhythmias, and even syncope, sudden death, a serious threat to life.
In medicine, bradycardia can be divided into three types: mild bradycardia, heart rate of 50 to 59 beats / min, mostly physiological, common in the elderly, exercise and sleep, the general asymptomatic. Personality A slight dizziness, chest tightness, palpitations, weakness. Moderate bradycardia, heart rate 35 to 49 beats / min, often accompanied by organic disease, continued to cause can lead to cardiovascular insufficiency, angina, heart function Incomplete, fainting, etc .. Severe bradycardia, heart rate less than 35 beats / min, often appear sinoatrial block, etc., serious life-threatening.
Bradycardia is common in the elderly over the age of 60, especially in the elderly with underlying diseases, such as diabetes, coronary heart disease, etc. Its common symptoms are dizziness, fatigue, fainting, black eyes and other current cerebral insufficiency series performance. Typical symptoms are dizziness, unresponsive, memory loss, fatigue, a little exercise on the shortness of breath, sudden breathing difficulties, chest tightness, chest pain and other systemic manifestations.
However, some bradycardia and no symptoms, or under normal circumstances the symptoms are not obvious, most of the occasional physical examination found .If the physical examination, cardiac examination (ECG, 24-hour Holter, echocardiography) report appears in the following text, even if There are no symptoms, but extra vigilance is required: bradycardia (electrocardiogram or 24-hour ambulatory ECG), long space (electrocardiogram or 24-hour ambulatory electrocardiogram), ventricular tachycardia (electrocardiogram or 24-hour ambulatory electrocardiogram) (Super report).
Cause bradycardia for a variety of reasons, if it is physiological, such as the athlete's physical fitness is good, the heart beat frequency slower than the average person, there will be physiological sinus bradycardia, the heart examination found no abnormalities, and no obvious symptoms , Can be temporarily untreated.If it is pathological, long-term continued variety of bradyarrhythmia can cause myocardial lesions, the need to actively look for and treatment of reversible causes.
Mild bradycardia (heart rate 50 to 60 beats / min), if asymptomatic or mild symptoms, without urgent treatment, over-treatment but will make the heart rate faster, but clinical should avoid using drugs that cause slow heart rate. Slower, need to improve the heart rate of traditional Chinese medicine or Western medicine, and clinical observation. Cardiovascular and cerebrovascular insufficiency, angina pectoris, cardiac insufficiency, syncope and other symptoms, the need to install pacemaker.
Chinese medicine can also prevent bradycardia bradycardia mostly manifested as delayed pulse, pulse knot, palpitations, chest tightness, aversion to cold, waist and knees, weakness or dizziness, dull or dentate tongue, or tongue Ecchymosis, ecchymosis, then most of the dialectical heart and kidney yang, qi stagnation and blood stasis, the treatment should use red ginseng, Epimedium, psoralen, medlar, ephedra, asarum, Salvia, leeches and other Chinese warming heart Kidney, blood circulation.Although the above Chinese medicine can improve bradycardia, but need to be under the guidance of a doctor dialectical medication.
