What is Atrial Fibrillation?
Atrial fibrillation (AFib or AF) is a type of arrhythmia, or abnormal heart rhythm. It occurs when the upper chambers of the heart (the atria) beat too fast and irregularly, which interferes with the flow of blood to the lower chambers of the heart (the ventricles). AFib is the most common type of arrhythmia, and it can cause symptoms such as chest pain, shortness of breath, dizziness, and fatigue.
What is Worse than Atrial Fibrillation?
Atrial fibrillation can be a serious condition, but there are other types of arrhythmias that can be even more dangerous. Ventricular tachycardia (VT) is an arrhythmia that occurs when the lower chambers of the heart beat too quickly and irregularly. It can cause a rapid pulse, lightheadedness, chest pain, and even cardiac arrest. Other serious arrhythmias include atrial flutter, ventricular fibrillation, and Wolff-Parkinson-White Syndrome. All of these conditions can be life-threatening and require immediate medical attention.
