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.
