Why the study?
Does the Valsalva maneuver elicit abnormal systemic arterial pressure and heart rate responses in patients with cardiovascular disease?
Does the Valsalva maneuver elicit abnormal systemic arterial pressure and heart rate responses in patients with cardiovascular disease?
The Valsalva maneuver may serve as a simple, dynamic stress test of the circulation, as the normal poststraining bradycardia is abolished in various cardiovascular diseases.
Answers are grounded in this paper and cite their sources.
May support Valsalva as bedside circulatory test in select diseases; leaves open prospective validation of diagnostic utility.
The normal response following sustained straining, as in a Valsalva maneuver, is a rise in systemic arterial pressure and a reflex slowing of the heart rate. This response was found to be abolished in some patients with mitral stenosis, with organic heart disease, with pulmonary vascular disease (including kyphoscoliosis), or with congenital heart disease. It was abolished in all three instances of pericardial disease studied. The relationship of the presence or absence of a poststraining bradycardia to cardiovascular dynamics at rest and on exercise as determined by right heart catheterization is presented, and the suggestion is made that the Valsalva maneuver, when performed under electrocardiographic control, may be a simple, dynamic stress test of the circulation. This suggestion is waiting for further exploration.
