The word arrhythmia can be defined as a lack of rhythm. Some references state they are synonyms for irregular heartbeat, and others define arrhythmia as irregular heartbeat and dysrhythmia as a disturbance to an otherwise normal rhythm. Throughout the text, we have chosen the term dysrhythmia. Antidysrhythmics include all medications that are used to treat any of these various dysrhythmias. The importance of dysrhythmia management in the modern practice of medicine cannot be overstated because dysrhythmias are among the most common causes of preventable sudden cardiac death.52
