difference between arrhythmias and dysrhythmias
Difference Between Arrhythmia and Dysrhythmia. Both arrhythmia and dysrhythmia mean the same. Arrhythmia means no regular rhythm and dysrhythmia means abnormal rhythm. Disturbances of cardiac rhythm or arrhythmias are common in people, often benign, and often intermittent. However, they can be severe sometimes leading to cardiac compromise.
