Which finding is most commonly associated with hyperthyroidism?

• A. Tachycardia
• B. Palpitations
• C. Thickened skin
• D. Apathetic attitude

Answer: (B)

Hyperthyroidism drives a faster, more active cardiovascular state because excess thyroid hormone increases metabolic rate and the sensitivity of the heart to sympathetic stimulation. This leads to a faster heartbeat and stronger contractions, so many patients notice their heart racing or skipping beats as a prominent symptom. That subjective awareness of a rapid or irregular pulse, described as palpitations, is the most commonly reported finding in hyperthyroidism. In contrast, thickened skin and apathy are more typical of hypothyroid states, not hyperthyroidism.
