What symptom does heart atrial fibrillation have

summary

Atrial fibrillation is not unfamiliar to everyone, atrial fibrillation is the abbreviation of atrial fibrillation, is a very common tachyarrhythmia. At present, the underlying cause of atrial fibrillation has not been found, but the diseases or factors related to atrial fibrillation, including hypertension, coronary heart disease, alcoholism, long-term mental stress, electrolyte or metabolic imbalance, severe infection, may also cause atrial fibrillation. Let's take a look at the following

What symptom does heart atrial fibrillation have

First, the symptoms of paroxysmal atrial fibrillation are sudden onset, palpitation, shortness of breath, precordial discomfort and anxiety. In the elderly with coronary heart disease, the ventricular rate is very fast at the onset of atrial fibrillation, vertigo, even syncope, sometimes heart failure and shock. The duration of each attack is different, the short one is only a few seconds, but it can occur frequently, and the elderly can last for several days to several weeks.

Second, persistent AF symptoms are associated with previous heart disease and ventricular rate. The main symptoms of this kind of atrial fibrillation are: palpitation, shortness of breath in patients with atrial fibrillation, especially the ventricular rate increases significantly after activity. Patients with persistent atrial fibrillation are prone to heart failure. Atrial fibrillation is prone to mural thrombosis due to atrial non contractility and hemodynamic disorder, leading to systemic and pulmonary embolism, especially cerebral embolism and limb arterial embolism.

Third: if there is no other heart disease, and the heart rate during atrial fibrillation is basically normal, the patient can not have any symptoms of atrial fibrillation, which is found by chance. If atrial fibrillation causes rapid heartbeat, the patient will have panic, shortness of breath, chest tightness, suffocation, panic, etc. if there is other heart disease, it will aggravate the symptoms of heart disease, especially heart failure.

matters needing attention

The symptoms of atrial fibrillation are also affected by the sensitivity and tolerance of patients' perceived symptoms. Some patients may have obvious symptoms when they first have atrial fibrillation. With the extension of the course of disease, some patients can gradually adapt, and the symptoms may be alleviated or even disappeared.
