Atrial fibrillation is one of the common arrhythmias, with a prevalence rate of about 2 to 4 percent. It is estimated that 300,000 to 400,000 people in Taiwan are affected. However, up to one-third of patients with atrial fibrillation are asymptomatic, and most of the symptomatic patients have paroxysmal seizures. The ECG does not detect the onset of atrial fibrillation. Therefore, doctors estimate that the number of diagnosed patients is actually serious.
underestimate. Undiagnosed and untreated atrial fibrillation puts patients at risk of stroke and sudden death. In addition, the higher the age of atrial fibrillation, the higher the prevalence rate. As Taiwan enters an aging society, while the proportion of the elderly population is gradually increasing, the proportion of atrial fibrillation is also gradually increasing, forming a healthy unexploded bomb of stroke and sudden death.
3 causes of sudden death are related to cardiovascular disease! Atrial fibrillation surges stroke and sudden death risk
Dr. Wen Mingxian, Chairman of the Cardiac Rhythm Medical Association of the Republic of China and Vice President of Chang Gung Memorial Hospital in Linkou, pointed out that heartbeats that are too slow or too fast belong to the category of arrhythmias. Although the sudden death rate of ventricular fibrillation and ventricular frequency pulse is higher, the incidence rate is not as good as that of atrial fibrillation. high.
Taiwan has become an aging society, and special attention should be paid to atrial fibrillation, which is more prevalent with age. When atrial fibrillation occurs, the heart is like trembling, unable to pump blood regularly. When blood stays in the atrium, the risk of blood clots increases; when the heartbeat returns to normal, blood clots easily reach the brain with blood flow, causing serious Stroke or increased risk of sudden death.
・Definition of sudden death: sudden fall to the ground and death within 24 hours without external injury
・Sudden cardiac death is the major cause of sudden death
・Causes of sudden cardiac death: coronary cardiovascular disease, heart failure, hereditary arrhythmia
Arrhythmia without symptoms is easy to ignore! Know the 4 risk factors for sudden death
70% of sudden deaths are caused by cardiovascular problems, but many people are at risk without knowing it; Dr. Zhang Kunzheng, deputy dean of the Department of Internal Medicine of the Hospital Affiliated to China Medical University, said that in 2016, in the medical journal “Mayo Clinic Proceedings”, a research analysis At that time, there were 2.7 million people in Taichung City, and according to the data of sudden cardiac death, it was found that about 19% were related to arrhythmia, and there were similar figures in Japan and South Korea, which were close to 20%. Dr. Zhang Kunzheng explained that some patients with arrhythmia have no obvious symptoms. It is easy to ignore that you are at risk of sudden death. Therefore, you should understand the risk factors and make a preliminary assessment yourself.
When you meet the category of high-risk groups, it is recommended to seek medical attention immediately.
Four major risk factors for sudden death “SACAF”:
・S: Gender (sex) men are at higher risk than women
・A: Age (age) is less than 65 years old
・C: Cardiovascular diseases (cardiovascular diseases) have a history of cardiovascular diseases
・AF: atrial fibrillation
Those who meet the above 4 risk factors have a particularly high chance of sudden death due to severe VT/VF (ventricular frequency and fibrillation), especially those with atrial fibrillation, which are 2.6 times more likely to die than ordinary people. Control the disease to avoid regrets.
The older you are, the more dangerous it is! A picture shows atrial fibrillation
Arrhythmia is not noticed, be careful asymptomatic sudden death crisis! Physician Zhang Bocheng from the Department of Cardiovascular Medicine, Chang Gung Memorial Hospital, Linkou said that about 70% of patients with arrhythmia will have palpitations, dyspnea, easy wheezing, chest tightness, dizziness and other symptoms, and patients tend to feel that their heartbeat is different from usual. Control, you can stay away from sudden death. Arrhythmias are primarily detected using an electrocardiogram, although an electrocardiogram can be used to diagnose arrhythmias. However, 30% of patients with arrhythmia are asymptomatic and have no obvious discomfort. Therefore, it is easy to neglect their own conditions. If they are not checked, diagnosed and treated in time, the disease is likely to continue to deteriorate.
Atrial fibrillation is very common in arrhythmia centers. Dr. Zhang Bocheng explained that the prevalence of atrial fibrillation in adults is about 2 to 4 percent. However, the prevalence increases with age.
For people over 70, the rate of atrial fibrillation is about 1 percent. to make. Because it is easy to cause blood clots and lead to stroke, patients need to take anticoagulants regularly to reduce the risk of stroke, and at the same time use drugs to control atrial fibrillation to prevent symptoms. If the condition is difficult to control with drugs, surgery can also be used to reduce the occurrence of atrial fibrillation and reduce the risk of sudden death; Dr. Zhang Bocheng said that patients must be treated according to the doctor’s instructions in order to prevent complications caused by arrhythmia and atrial fibrillation.
Seek medical attention immediately! Remember 543 stay away from the threat of sudden death
In addition, among the elderly over the age of 80, about 1 in 10 has atrial fibrillation. If the patient has other chronic diseases, such as diabetes and high blood pressure, the risk of atrial fibrillation is higher; Taipei Veterans General Hospital Department of Internal Medicine Dr. Zhao Zifan of Cardiology Department reminded that asymptomatic patients with atrial fibrillation have the same risk of stroke as symptomatic patients. Therefore, if you find that you have risk factors, you must go to the Cardiology Department of the hospital for an examination. If you find that your heartbeat is often irregular, fast and slow , be sure to go to the hospital for examination as soon as possible.
