| Summary: | Postural Orthostatic Tachycardia Syndrome (POTS) is a rare heterogeneous syndrome secondary to a disorder of the autonomic nervous system, characterized by sustained symptomatic sinus tachycardia in the upright position without arterial hypotension. Chronic symptoms are nonspecific and involve multiple organ systems, often leading to debilitating effects on the individuals quality of life. Although relatively unfamiliar to cardiologists, it is an essential entity in the differential diagnosis of pre-syncope. We present a case report of an adolescent referred to pediatric cardiology to investigate intermittent and recurrent episodes of sweating, chest pain, muscle weakness without loss of consciousness, palpitations, pallor, and tachycardia. During the medical history, she also reported other symptoms impacting her daily activities and school performance. Following a comprehensive physical examination (including heart rate and blood pressure assessment) and additional tests (electrocardiogram, transthoracic echocardiogram, and Tilt Test), she was diagnosed with POTS. Subsequently, a treatment plan, both pharmacological and non-pharmacological, was initiated, resulting in an improvement in her quality of life and symptom control. Recognition of this recently described medical condition depends on clinical suspicion during the medical history and physical examination, allowing for the implementation of treatment with the aim of enhancing the patients quality of life. |
