DysrhythmiasFree Board Review Questions CME Quiz
Dysrhythmias are found in a vast range of conditions and may be defined in a number of ways, including by site of origin (e.g., supraventricular, ventricular, atrial), mechanism of disturbance (e.g., fibrillation, automaticity, reentry or triggered activity), rate of disturbance (e.g., tachycardia, bradycardia) and electrocardiogram appearance (e.g., long QT syndrome). Dysrhythmias may be acute or chronic, and some (especially ventricular arrhythmias) may be life-threatening. Sudden cardiac death is the most severe manifestation of dysrhythmias (e.g., ventricular fibrillation).
This week's Med-Challenger's free CME quiz includes several dysrhythmias board review questions in topics include conduction disorders, pharmacology, supraventricular findings, and more.
