Misconceptions about Arrhythmias
Misconception: Atrial fibrillation or flutter only occurs in the elderly
Truth: Atrial fibrillation or flutter is common in the elderly, especially those aged 80 years or older, but it can occur in all age groups. In adults over the age of 55, this condition is found in less than 1 in 1000 people. However, the lifetime risk of developing this condition is about 18 – 25%. The causes of this condition vary, such as after an accident, certain medications, and myocardial ischemia.
Misconception: The main risk factor for atrial fibrillation or flutter is acute myocardial ischemia.
Truth: Patients with atrial fibrillation or flutter often present with symptoms of palpitations, leading to the misunderstanding that it is acute myocardial ischemia. In reality, the most important risk factor for atrial fibrillation or flutter is stroke, which occurs when a blood clot from the heart enters the bloodstream and blocks a brain artery, leading to conditions like paralysis. Risk factors for stroke vary between patients, depending on whether the individual has more or fewer risk factors. This should be assessed by a cardiologist. Patients with atrial fibrillation or flutter who are at high risk of stroke are advised to take anticoagulants to prevent and reduce the risk of stroke.
Misconception: Electric shock therapy or cardioversion can cure arrhythmias.
Truth: Although cardioversion can normalize the rhythm of an arrhythmic heart, it is not a cure. Often, after an electric shock, the heart may return to normal rhythm, but the arrhythmia can occur again at any time. The causes of this condition are varied, such as after an accident, certain medications, and myocardial ischemia.
Misconception: Arrhythmias or atrial fibrillation/flutter can be completely cured.
Truth: The cure for arrhythmias or atrial fibrillation/flutter depends on the cause. For example, thyroid disease or excessive alcohol consumption could cause arrhythmias or atrial fibrillation/flutter. If treated correctly, arrhythmias or atrial fibrillation/flutter can typically be cured. Conversely, if the arrhythmias or atrial fibrillation/flutter are due to other causes such as hypertension or myocardial ischemia, even if these conditions are treated, the arrhythmias or atrial fibrillation/flutter may not be completely cured but can be managed. If you have questions about arrhythmias or atrial fibrillation/flutter, it is recommended to consult a cardiologist.
