What safety issues should patients with arrhythmia consider when preparing to drive or operate machinery?

If there have been recent sudden palpitations, dizziness, near-fainting, or loss of consciousness, driving and operating dangerous machinery should be paused, and a doctor should be consulted promptly about individualized restrictions. Whether it is safe to resume depends on symptoms, test results, treatment, and local regulations, and cannot be decided based solely on how one feels.
