Objectives: To compare the levels of cortisol in patients of vasovagal syncope (VVS) and postural tachycardia syndrome (POTS).
Methods: A cross-sectional analytical study was conducted at Islamic International Medical College, Rawalpindi and Electrophysiology Department at (AFIC). This study included 80 subjects, comprising of 35 patients in each group of vasovagal syncope and postural tachycardia syndrome and 10 healthy subjects. Patients with complaint of syncope was evaluated for vasovagal syncope and postural tachycardia syndrome using Head Up Tilt Test (HUTT. Blood samples of all the participants were taken and serum cortisol was analyzed using ELISA method. Results were analyzed on SPSS Statistics 21 using ANOVA with a p value of ≤0.05 regarded as significant.
Results: Hormonal analysis shows that cortisol levels in the vasovagal, postural tachycardia syndrome and in control group was 153±16.7pg/ml, 160.17±pg/ml, and 69.65± 5.8pg/ml respectively. Cortisol levels were significantly higher in both vasovagal and POTS groups as compared to controls with a p-value of 0.04 and 0.023 respectively. However, there was no significant difference between vasovagal and POTS patients with p value 0.570.
Conclusion: It is concluded from the study that cortisol responses of VVS and POTS were positive.

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of cardiovascular autonomic disorders characterized by orthostatic intolerance and a symptomatic increase in heart rate upon standing, which can significantly impair patients' quality of life. Its pathophysiology is complex, multifactorial; thus, a variety of treatment approaches have been investigated. Recent studies have identified three primary POTS phenotypes-hyperadrenergic, neuropathic, and hypovolemic-each requiring tailored management strategies.

: Patients with postural orthostatic tachycardia syndrome (POTS) or neurogenic orthostatic hypotension (nOH) experience vertigo, confusion, and syncope. Compression garments help reduce venous pooling in these patients, thereby increasing cardiac output. We aimed to determine end-user opinions of compression products intended to alleviate symptoms for POTS and nOH.

Article Synopsis
- Postural orthostatic tachycardia syndrome (POTS) mainly affects young females during puberty and early adulthood, leading to symptoms like lightheadedness, palpitations, weakness, and fatigue.
- These symptoms not only affect daily life but also contribute to mental health issues such as anxiety and depression, highlighting the importance of support in academic environments.
- There is a lack of research and standardized treatment guidelines for POTS, indicating a need for increased awareness, collaboration among healthcare professionals, educators, and policymakers to improve care for affected individuals.
