Diastolic Blood Pressure Rise During Valsalva as a Surrogate for Sympathetic Activation to Identify Functional Hyperadrenergic Postural Tachycardia Syndrome

2025-09-05

Abstract excerpt

<title>Abstract</title> <p> <bold>Purpose</bold> Muscle sympathetic nerve activity (MSNA) is valuable for POTS management, but microneurography is clinically impractical. We investigated whether the Valsalva phase 2 diastolic blood pressure rise (DBP <sub>VM2l_rise</sub> ) could be a surrogate for MSNA during the Valsalva and be used to identify hyperadrenergic POTS. <bold>Methods</bold> We included 21 POTS...
