"Abnormal ECG: That's a problem?

■ Atrial fibrillation



Atrial fibrillation increases with age, and the prevalence rises sharply after age 60. It is said that people over the age of 80 reach total10%.

Atrial fibrillation means that the heart moves finely, that is, moves quickly . However, the electrical signal is not transmitted to the ventricle as it is, but is transmitted irregularly to the ventricle, and the heart itself contracts about 60 to 150 times per minute. The pulse is completely disjointed, but the symptoms vary from person to person. Some people complain of palpitations and shortness of breath, while others have no symptoms at all.

Atrial fibrillation


​f wave

We recognize atrial waves called f waves. The pulse is disjointed irregular.

<Clinical significance of atrial fibrillation>


Atrial fibrillation is not a life-threatening and dangerous arrhythmia. The most problematic part of atrial fibrillation is cardiogenic cerebral embolism, which occurs when a blood clot forms in the heart and then flies to the brain. 

Observational studies from the Framingham study in the United States report that patients with atrial fibrillation have a worse prognosis. This is because patients with atrial fibrillation are overwhelmingly at increased risk of thromboembolism, including stroke.


A: 55-74 years old


B: 75-94 years old



Atrial fibrillation, as mentioned above, has a high risk of stroke and requires treatment.

Treatment has two major axes, one is anticoagulant therapy to prevent cerebral infarction and the other is defibrillation therapy to restore arrhythmia to its normal pulse. The choice of treatment depends on each patient's condition. At CVIC, cardiologists provide medical care with the latest knowledge, so please feel free to consult us.
