The consensus statement from the Heart Rhythm Society recommends a complete history and physical examination with orthostatic vital signs and 12-lead ECG for all patients who are assessed for POTS. The head-up tilt table (HUT) with noninvasive hemodynamic monitoring is the criterion standard for assessing orthostatic intolerance in this setting.
The HRS also suggests that complete blood cell count and thyroid function studies may be useful for selected patients. Although the clinical efficacy of a 24-hour Holter monitor is uncertain, it may be considered in certain patients. Additional studies (eg, transthoracic echocardiography, detailed autonomic testing, exercise stress testing) may also be considered in selected patients.
