What symptom does heart atrial fibrillation have?

summary

Atrial fibrillation, referred to as atrial fibrillation, is a common persistent arrhythmia. The frequency of atrial activation during atrial fibrillation is 300-600 beats / min, and the heart rate is often fast and irregular. The incidence rate of atrial fibrillation is 0.4%. The incidence of atrial fibrillation increases with age, and 10% of people over 75 years old. What symptom does heart atrial fibrillation have? Let's talk about it

What symptom does heart atrial fibrillation have?

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, short only a few seconds, can be frequent attacks, the elderly can last for several days to several weeks, patients usually have to endure the pain of the disease for a long time.

The sensitivity and tolerance of patients' perception of symptoms sometimes affect the symptoms of AF. Some patients may have obvious symptoms when they just have atrial fibrillation. With the prolongation of the course of disease, some patients can gradually adapt, and the symptoms may be alleviated or even disappeared.

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, which leads to systemic and pulmonary embolism and other symptoms of atrial fibrillation. Among these symptoms, cerebral embolism and limb arterial embolism are the most common.

matters needing attention

Some patients may need to avoid caffeine containing substances such as tea, coffee, cola and some over-the-counter drugs. Be careful with some cough or cold medications.
