Final answer:
Examples of Supraventricular Dysrhythmias include Atrial fibrillation and atrial flutter, both of which are types of arrhythmias originating above the heart's ventricles.
Step-by-step explanation:
Examples of Supraventricular Dysrhythmias (SVD) include Atrial fibrillation and atrial flutter. These are types of supraventricular tachycardias, which are arrhythmias that originate above the ventricles of the heart.
In atrial fibrillation, the electrical pattern is abnormal prior to the QRS complex, and the heart rate is often increased. Atrial flutter also originates above the ventricles, but typically features a more organized rhythm than atrial fibrillation.
Ventricular arrhythmias, such as ventricular fibrillation and ventricular tachycardia, originate in the lower chambers of the heart and are considered distinct from SVDs. Bradycardias, like sinus bradycardia, and blocks such as atrioventricular block and bundle branch block, are also separate categories of heart rhythm disorders.
