A 45‑yeаr‑оld wоmаn cоmes to the clinic feeling tired, light‑heаded, and colder than usual. Her blood pressure is 100/65 mmHg, and her heart rate is 58 bpm. Lab tests show low thyroid hormone levels, suggesting hypothyroidism. An exam of her heart shows an end‑diastolic volume (EDV) of 120 mL and an end‑systolic volume (ESV) of 80 mL. Calculate her stroke volume. Then explain how low thyroid hormone levels could affect her heart rate, stroke volume, and overall circulation. Describe how these changes might lead to the symptoms she is experiencing.
