Arrhythmias

Arrhythmias are abnormalities in the heart's rhythm, resulting from irregular electrical impulses that can lead to either an excessively fast, slow, or erratic heartbeat. They are clinically significant as they can compromise cardiac output, leading to symptoms such as palpitations, dizziness, or even sudden cardiac arrest. A common example is atrial fibrillation, which increases the risk of stroke due to potential thrombus formation in the left atrium.

Arrhythmias are abnormalities in the heart's rhythm, resulting from irregular electrical impulses that can lead to a heart rate that is too fast, too slow, or erratic. They are clinically significant as they can cause symptoms ranging from palpitations to syncope and may lead to serious complications such as stroke or sudden cardiac arrest. A common example is atrial fibrillation, which increases the risk of thromboembolic events due to ineffective atrial contraction.
