Modified Valsalva Maneuver vs. Standard Valsalva Maneuver on Emergency Department Patients Presenting with Supraventricular Tachycardia
Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform t...
متن کاملEvaluation of lacrimal drainage system by radionuclide dacryoscintigraphy in patients with epiphora
Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...
متن کاملPhysiology-based MR imaging assessment of CSF flow at the foramen magnum with a valsalva maneuver.
BACKGROUND AND PURPOSE MR imaging is currently not used to evaluate CSF flow changes due to short-lasting physiological maneuvers. The purpose of this study was to evaluate the ability of MR imaging to assess the CSF flow response to a Valsalva maneuver in healthy participants. MATERIALS AND METHODS A cardiac-gated fast cine-PC sequence with ≤15-second acquisition time was used to assess CSF ...
متن کاملValsalva Maneuver and Strain-Related ECG Changes
BACKGROUND During the four steps of the Valsalva maneuver (VM), opposite changes can be observed in some physiologic parameters. Manifestations of the VM in the electrocardiogram (ECG) have been studied in detail, but there have been few reports comparing VM-related biochemical and hemodynamic changes with a focus on the strain phase of the VM. OBJECTIVES We studied strain-related ECG changes...
