There are many people with cardiovascular disease who take a report and ask, "Doctor, am I having arrhythmias?" "Indeed, arrhythmias are one of the most common symptoms of many cardiovascular diseases. However, its harm cannot be ignored because of its commonness, once the arrhythmia occurs, it causes the patient to have difficulty breathing, leading to heart failure; the heavy directly leads to sudden death. Today we will talk in detail about the harm caused by arrhythmias to the human body.
【1】What is arrhythmia?
The heart is divided into four parts, namely the left atrium, the right atrium, the left ventricle, and the right ventricle. In the upper margin of the right atrium, there is a tissue called the sinus node, which is the commander who controls the heartbeat of the human body. The number of heartbeats per minute of the human body is carried out regularly according to the command of the sinoatrial node, generally 60 to 100 times per minute. When the number of heartbeats per minute is less than 60 or higher than 100 due to various internal or external factors, we call arrhythmias.
There are many causes of arrhythmias, such as exercise, mood swings, sleep, etc. will cause arrhythmias, but in general, this arrhythmia belongs to physiological arrhythmias and does not need treatment. What needs to be treated is an arrhythmia caused by various pathological factors.
Common pathological factors that cause arrhythmias include congenital heart disease caused by genetic mutations, coronary heart disease, hypertensive heart disease, myocarditis, rheumatic heart disease, valvular disease, cardiomyopathy and other cardiovascular diseases, drug toxicity, acid-base balance and electrolyte imbalances, nerve and humoral regulation dysfunction and other systemic disease causes, as well as hyperfunction of glands, stroke and other extracardiac organ function or structural changes.
【2】What are the symptoms of arrhythmias?
Since the causes of the arrhythmia are different, the symptoms of the arrhythmia will be different. In general, the severity of the symptoms of arrhythmias and other clinical symptoms caused by arrhythmias are determined by the type, duration, and severity of the primary disease. Some patients show obvious clinical symptoms, but many patients do not have any symptoms in the early stages of the disease.
In the early stages of the disease, patients with arrhythmias exhibit typical symptoms such as palpitations, sweating, fatigue, dyspnea, and chest tightness. At this time, if the heart rhythm returns to normal, the above symptoms will disappear, if the heart rate does not return to normal, but further development, it will lead to dizziness, confusion, syncope, and even sudden death.
Arrhythmias can also cause many corresponding accompanying symptoms in the major organs of the body, such as blurred vision, dizziness, blackness, syncope and other symptoms in the brain; the kidneys will also have urinary frequency and urgency caused by damage; there will also be abdominal distension, abdominal pain, diarrhea and other gastrointestinal symptoms; and chest tightness, shortness of breath, breathing difficulties and other symptoms are more common.
