What are the causes of atrial fibrillation? What factors are involved in the occurrence of atrial fi

The most common symptom of atrial fibrillation is palpitation and shortness of breath. It is normal for most people to experience symptoms of palpitation and shortness of breath during intense activity. However, patients with atrial fibrillation are different in that they will have symptoms of palpitation, discomfort and shortness of breath from time to time when they are resting.

The symptoms are different from those that occur when we are active. In addition, it is more common to have cold hands and feet, due to the loss of part of the heart function during atrial fibrillation, the blood that is beaten out of the heart and the blood that flows back to the heart is not enough, that is, the amount of heart output is not enough. At this time, the peripheral blood vessels will constrict, causing cold hands and feet.

Some symptoms, such as dizziness or even fainting, are due to the fact that the heart pumps less blood during atrial fibrillation, and the blood supply to the cerebral blood vessels will also be reduced, especially when standing up from a sitting position. In addition, due to the irregular heart rate in atrial fibrillation, sometimes some patients will have long intermissions, that is, the heart will not beat for a long time, and at this time, the patient will appear black in front of his eyes or even faint.

The common ** are rheumatic heart disease, coronary heart disease, hyperthyroidism, etc.

Epidemiology. The incidence increases with age, reaching 10% in 75 years of age.

The reasons for this are varied, but what is happening now.

Atrial fibrillation is a common arrhythmia, the symptoms of atrial fibrillation are affected by the speed of the ventricular rate, if the heart rate is not fast, the patient can have no obvious symptoms, and atrial fibrillation can be found by doing an electrocardiogram. If the heart rate exceeds 150 beats per minute, the patient may have angina pectoris or congestive heart failure.

Secondly, the common symptoms of atrial fibrillation are palpitations, palpitations, chest tightness, shortness of breath, and difficulty breathing. If the patient has underlying coronary artery disease, chest pain can be induced. If the patient has underlying cardiac insufficiency, it can also induce an acute attack of heart failure.

Thirdly, atrial fibrillation is also prone to embolism of the systemic circulation, such as cerebral embolism.

Therefore, patients with atrial fibrillation have clinical manifestations of palpitations and palpitations due to tachycardia. It can also induce the deterioration of cardiac function due to tachycardia, and even acute left heart failure, and a small number of patients have cerebral insufficiency due to tachycardia, manifested as TIA and even syncope. In addition, if the atria cannot contract and relax normally, it will cause a blood clot to form in the left atrial appendage, and after the blood clot falls off, it will cause cerebral embolism

What are the general manifestations of atrial fibrillation? During atrial fibrillation, the atria lose their system function and blood tends to stagnate and form blood clots in the atrium. When the throttle is lowered, it can travel with the blood to various parts of the body, causing cerebral embolism (stroke), limb artery embolism (in severe cases, even amputation), etc.

Risk factors for stroke in patients with atrial fibrillation include a history of previous embolism, hypertension, diabetes, and coronary heart disease. Common clinical symptoms of atrial fibrillation include palpitations, dizziness, chest tightness, heartache, shortness of breath, etc., and sometimes accompanied by gastrointestinal discomfort such as nausea and vomiting.

Symptoms of heart failure and atrial fibrillation generally include bradycardia, chest tightness with palpitations, and shortness of breath. Atrial fibrillation is still caused by rheumatic heart disease, coronary heart disease, or hyperthyroidism. Atrial fibrillation is typical of arrhythmias.

This condition can manifest as chest tightness. The main symptoms of patients with atrial fibrillation are shortness of breath, chest tightness, difficulty breathing, dizziness, and rapid heartbeat. When atrial fibrillation accelerates, not only does the heart beat faster, but instead of fighting for the spirit, the function of the atrial system is affected.

The heart is one of the important parts of the body, but various heart diseases are risk factors that threaten heart health, and atrial fibrillation is one such disease. If you have the following symptoms, it may be atria and palpitations. This condition requires clinical research.

Typical signs in patients with atrial fibrillation are OS: on cardiac auscultation, the intensity of the first cardiac SOM can be heard, and the heart rate is absolutely irregular. Because cardiac output decreases to varying degrees in some cardiac cycles, medications should be administered**.

At the same time, it should be noted that some patients with rapid atrial fibrillation will experience symptoms such as dyspnea, general fatigue, and palpitations; When atrial fibrillation is accompanied by heart failure, patients experience dyspnea, palpitations, fatigue, and dyspnea; When patients with atrial fibrillation induce cerebral thrombosis and fruit rest, rapid atrial fibrillation will occur, with symptoms such as dyspnea, general fatigue, and palpitations; When atrial fibrillation is accompanied by heart failure, patients experience dyspnea, palpitations, fatigue, and dyspnea; When atrial fibrillation induces cerebral thrombosis.

We often say that the heart is the source of life, and it is true, the heart, as one of the main organs of the human body, is mainly responsible for carrying the transportation of blood, and the heart is like a water pump, providing power for our blood, so that we can function normally. However, if there is a problem with this pump, it will cause discomfort in all aspects of the body, and arrhythmia is one of the common problems of the heart. Today we will talk about the symptoms of atrial fibrillation.

For atrial fibrillation, it can be divided into paroxysmal and persistent, when paroxysmal atrial fibrillation attacks, the frequency is not fast, the symptoms are not obvious, patients will have palpitations, palpitations, irritability, fatigue and other manifestations. The symptoms of persistent atrial fibrillation are related to the underlying heart disease, but also to the speed of the ventricular rate, which increases significantly after physical activity and the phenomenon of syncope.

Atrial fibrillation is the most common sustained arrhythmia. The symptoms of atrial fibrillation vary from person to person, but the most common symptom is palpitation, and some people may even feel tightness in the chest and shortness of breath. Most patients are prone to atrial fibrillation after exertion and alcohol consumption, and they tend to have nighttime attacks, but the pattern of seizures is generally not fixed.

In addition, there will be dizziness, precordial pain, pressure or discomfort, because atrial fibrillation will cause blood problems, so it will cause dizziness and other symptoms. In addition, due to the arrhythmia, it will inevitably lead to changes in the part of the heart, leading to problems such as pain in the precordial area.

In short, atrial fibrillation has brought great distress to patients, and it is also a difficult problem. Generally, the first attempt is to control the patient's heart rate to maintain the stability of the patient's heart rate, and it cannot be completely **. At the same time, patients with atrial fibrillation should also pay attention to quitting smoking, limiting alcohol consumption, some patients may need to avoid substances containing caffeine, such as tea, coffee, cola, etc., and should be cautious about using cold medicines.

Symptoms such as palpitations, rapid heartbeat, chest tightness, dizziness, shortness of breath, irritability, and lack of strength in the whole body will occur.

The symptoms of atrial fibrillation are mainly manifested as the following:

1. Paroxysmal atrial fibrillation: Sudden onset, palpitations, shortness of breath, precordial discomfort and anxiety. Each episode can last anywhere from a few seconds to a few seconds, from a few days to several weeks in the elderly.

2. Persistent atrial fibrillation: mainly related to ventricular rate, manifested as: palpitations, shortness of breath, especially when the ventricular rate increases significantly after activity, and patients with persistent atrial fibrillation are prone to heart failure.

In atrial fibrillation, due to the lack of atrial contractility and hemodynamic disorders, mural thrombosis is prone to occur, resulting in systemic and pulmonary circulation embolism, with cerebral embolism and limb arterial embolism being the most common.

3. If there is no other heart disease, the ventricular rate is basically normal during atrial fibrillation, and the patient can have no symptoms, if there are other heart diseases, it will aggravate the symptoms of heart disease, especially heart failure.

Fourth, the symptoms of atrial fibrillation are also affected by the sensitivity and tolerance of the patient's perception of symptoms, some patients can have obvious symptoms when they first develop atrial fibrillation, and with the prolongation of the course of the disease, some patients can gradually adapt, and the symptoms may be reduced or even disappeared.
