What does the term "dysrhythmia" refer to?

The term "dysrhythmia" specifically refers to an abnormal heart rhythm. This can encompass a wide range of irregularities in the heart's electrical conduction system, resulting in rhythms that may be too fast, too slow, or erratic. Dysrhythmias can result from various factors including electrolyte imbalances, ischemia, or structural heart disease. Understanding this term is critical for recognizing and managing conditions that may lead to significant cardiovascular complications.

Normal heart rhythm would indicate the absence of dysrhythmia, while both increased and decreased heart rates can describe a type of dysrhythmia, but they do not encapsulate the broader idea of abnormal rhythms that encompass various forms of irregularities.
