Cooccurrence of Postural Orthostatic Tachycardia Syndrome with Two Different Clinical Entities

Case Reports in Pediatrics, 2016
Postural orthostatic tachycardia syndrome (POTS) is an abnormal heart rate response to a positional change. Several potential mechanisms for pathophysiology of POTS are defined. This syndrome can coexist with different clinical situations. In our report,

Tilt table testing, methodology and practical insights for the clinic

Clinical Physiology and Functional Imaging, 2023
AbstractTilt table testing (TTT) has been used for decades to study short‐term blood pressure (BP) and heart rate regulation during orthostatic challenges. TTT provokes vasovagal reflex in many syncope patients as a background of widespread use.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Diagnostic value of the tilt-table test for the assessment of syncope in children and adolescents

Arquivos Brasileiros de Cardiologia, 2001
OBJECTIVE - To assess the diagnostic value, the characteristics, and feasibility of tilt-table testing in children and adolescents. METHODS - From August 1991 to June 1997, we retrospectively assessed 94 patients under the age of 18 years who had a ...

Syncope associated with supraventricular tachycardia: Diagnostic role of implantable loop recorders

Annals of Noninvasive Electrocardiology, 2021
Syncope represents a relatively uncommon symptom of supraventricular tachycardia (SVT). It is likely that an impaired autonomic vasomotor response to the hemodynamic stress of tachycardia is the determinant of hemodynamic changes leading to cerebral ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Periosteal pressure sensitivity of the chest bone as a measure for autonomic function in ischemic heart disease

Frontiers in Neuroscience
PurposeIn 177 patients with ischemic heart disease and elevated periosteal pain sensitivity of the chest bone indicative of autonomic nervous system dysfunction, we test the hypotheses, (i) there is an association between the tilt table responses for the

Pulsed Wave Doppler Ultrasound Is Useful to Assess Vasomotor Response in Patients with Multiple System Atrophy and Well Correlated with Tilt Table Study

The Scientific World Journal, 2012
The study aim was to assess sympathetic vasomotor response (SVR) by using pulsed wave Doppler (PWD) ultrasound in patients with multiple system atrophy (MSA) and correlate with the tilt table study.
