Atrioventricular block: This arrhythmia occurs when electrical signals struggle to move from the atria to the ventricles.Bradyarrhythmia: This refers to an unusually low resting heart rate.It can stop the heart from pumping enough blood to the body. Sinus-node dysfunction: This arrhythmia arises from the sinus node, which is toward the top of the right atrium.The AV node is a small structure toward the center of the heart. Supraventricular arrhythmic tachycardia: This is when the heart beats too quickly and irregularly due to a problem above the atrioventricular (AV) node.Ventricular arrhythmic tachycardia: This is when the lower chambers of the heart (ventricles) beat too quickly and irregularly.The following arrhythmia can arise from stroke: If those clots travel to the brain, they can cause a stroke. When they beat irregularly, blood can pool within them, eventually forming clots. Which types of arrhythmia are associated with stroke?Īccording to a 2022 paper, atrial fibrillation is an arrhythmia that can lead to stroke.Ītrial fibrillation (AFIb) is when the upper chambers of the heart (atria) beat with an irregular rhythm. However, healthcare professionals do not yet understand why this occurs, and there may be several factors that might be involved, such as: This risk gradually declined during the 72-hour window. The study also found that the risk of arrhythmia was highest within 24 hours of entering the stroke unit. The study found that roughly 25.1% of its participants had an arrhythmia. An older 2012 study measured the rates of arrhythmia within 72 hours of entering a stroke unit. Having an arrhythmia can mean that a person is roughly five times more likely to have a stroke relative to the general population.Īdditionally, strokes may have an association with arrhythmia onset. doi:10.According to a 2022 review, some arrhythmias are a leading cardiac cause of stroke.
