Abstract
Sinus node dysfunction is often due to degeneration of the heart's impulse-generating system. We report a case of a 40-year-old woman with a recent gastric sleeve surgery, who presented with symptomatic sinus bradycardia following significant post-surgical weight loss. Extensive workup excluded common causes such as electrolyte disturbances, hypothyroidism, or cardiomyopathy. We hypothesize that alterations in leptin metabolism due to weight loss triggered increased vagal stimulation, leading to her bradycardia. The patient was treated with theophylline as a noninvasive alternative to pacemaker implantation. Long-term monitoring showed partial improvement in heart rate. This case highlights the need for vigilance in managing bradycardia as a potential side effect of bariatric surgery-induced weight loss, emphasizing the importance of follow-up and the potential role of leptin in heart rate regulation.
期刊介绍：
SAGE Open Medical Case Reports (indexed in PubMed Central) is a peer reviewed, open access journal. It aims to provide a publication home for short case reports and case series, which often do not find a place in traditional primary research journals, but provide key insights into real medical cases that are essential for physicians, and may ultimately help to improve patient outcomes. SAGE Open Medical Case Reports does not limit content due to page budgets or thematic significance. Papers are subject to rigorous peer review and are selected on the basis of whether the research is sound and deserves publication. By virtue of not restricting papers to a narrow discipline, SAGE Open Medical Case Reports facilitates the discovery of the connections between papers, whether within or between disciplines. Case reports can span the full spectrum of medicine across the health sciences in the broadest sense, including: Allergy/Immunology Anaesthesia/Pain Cardiovascular Critical Care/ Emergency Medicine Dentistry Dermatology Diabetes/Endocrinology Epidemiology/Public Health Gastroenterology/Hepatology Geriatrics/Gerontology Haematology Infectious Diseases Mental Health/Psychiatry Nephrology Neurology Nursing Obstetrics/Gynaecology Oncology Ophthalmology Orthopaedics/Rehabilitation/Occupational Therapy Otolaryngology Palliative Medicine Pathology Pharmacoeconomics/health economics Pharmacoepidemiology/Drug safety Psychopharmacology Radiology Respiratory Medicine Rheumatology/ Clinical Immunology Sports Medicine Surgery Toxicology Urology Women''s Health.
