What is the common term for an abnormal heart rhythm caused by an electrolyte imbalance?

An abnormal heart rhythm that results from an electrolyte imbalance is commonly referred to as arrhythmia. This term encompasses a range of conditions where the electrical impulses in the heart do not function correctly, leading to irregular heartbeats. Electrolytes, such as potassium, sodium, calcium, and magnesium, play crucial roles in maintaining the heart's electrical stability and function. When these levels are disrupted, it can alter the heart's rhythm, causing arrhythmias.

Bradycardia refers specifically to a slower than usual heart rate, while tachycardia refers to a faster than usual heart rate. Both are specific types of arrhythmias, but they do not capture the broad range of abnormal rhythms that can occur due to electrolyte imbalances. Hypertension, on the other hand, is high blood pressure and is not directly related to heart rhythm abnormalities caused by electrolyte disturbances. Understanding these distinctions helps clarify why the term arrhythmia is the most accurate descriptor in this context.
