Characteristics of endometriosis patients referred for tilt table testing

The rising incidence of Postural Orthostatic Tachycardia Syndrome (POTS) has presented a clinical challenge, as these patients can be refractory to traditional interventions. The aim of this study was to characterize clinical and demographic factors of endometriosis patients who were referred for the tilt table test. 297 endometriosis patients confirmed by laparoscopic biopsy and who completed a tilt table were identified via the electronic medical record (EMR). Descriptive statistics were performed and t-test comparisons represented between group differences. 26.2% of patients had a positive tilt table for POTS. Those with POTS were more likely to be younger ( p < 0.001), non-Hispanic ( p = 0.003), and be diagnosed with EDS ( p = 0.02). They were more likely to be prescribed cardiovascular agents and have an intrauterine device (IUD). There were no differences between groups for prevalence or severity of gastroparesis, depression, anxiety, or self-reported symptoms of autonomic dysfunction. Future study is warranted to determine the clinical significance of POTS in women with endometriosis.
