This document describes treatment options for arrhythmia, which include lifestyle changes, medication, devices, ablation procedures, and surgery. The document also reviews factors to consider when determining appropriate arrhythmia treatment, including the nature and severity of the heart rhythm disorder and its symptoms, and underlying diseases and other conditions that contribute to the disorder or affect the patient's health or quality of life.
