Valsalva test

Val·sal·va test

(vahl-sahl'vă),
the heart is monitored by ECG, pressure recording, or other methods while the patient performs the Valsalva maneuver; carciac volume decreases in unaffected patients but may dilate in the patient with impaired myocardial reserve; there is a characteristic complex sequence of cardiocirculatory events, departure from which indicates disease or malfunction.

aneurysm of sinus of Valsalva - a congenital thin-walled tubular out-pouching usually in the right or noncoronary sinus with an entirely intracardiac course.
teniae of Valsalva - the three bands in which the longitudinal muscular fibers of the large intestine, except the rectum, are collected. Synonym(s): teniae coli
Valsalva antrum - a cavity in the petrous portion of the temporal bone. Synonym(s): mastoid antrum
Valsalva ligaments - the three ligaments that attach the auricle to the side of the head. Synonym(s): auricular ligaments
Valsalva maneuver - any forced expiratory effort against a closed airway.
Valsalva muscle - a band of vertical muscular fibers on the outer surface of the tragus of the ear. Synonym(s): tragicus muscle
Valsalva sinus - the space between the superior aspect of each cusp of the aortic valve and the dilated portion of the wall of the ascending aorta. Synonym(s): aortic sinus

The tests included in the software are RR variability at rest (over 170 intervals, 5, 10, or 30 min), RR variability during deep breathing, Valsalva test (10 or 15 s), and orthostasis test.

The valsalva test has been found to have 22% sensitivity and 95% specificity.
Significant differences in HF values between groups were observed at the 5th minute of inspiration-expiration test (for FMS group- 35.2 [msec.sup.2] (15.9-60.6); for control group-56.4 [msec.sup.2] (29.2-89.8), p = 0.030) and at the 5th minute of Valsalva test (for FMS group-27.9 [msec.sup.2] (17.8-49.6); for control group-55.1 [msec.sup.2] (17.0-103.3), p = 0.032).
We determined decreased parasympathetic and increased sympathetic activity during orthostatic stress (stand and supine tests), inspiration-expiration and Valsalva test in FMS patients.
This procedure was performed thrice and the average of the ratio from the 3 Valsalva tests was considered as the final result.
