Title: Which cardiac variable may be affected in mitral valve prolapse? Post by: Anon12398 on Oct 14, 2016 Mitral valve prolapse. When the mitral valve does not close properly the leaflets of the mitral valve bulge upward, or prolapse into the atrium as the ventricle contracts. This may lead to blood leaking backward from the ventricle into the atrium. Which cardiac variable may be affected in mitral valve prolapse?
A. decreased heart rate B. increased heart rate C. decreased stroke volume D. increased stroke volume Title: Re: Which cardiac variable may be affected in mitral valve prolapse? Post by: habiba on Oct 14, 2016 The left ventricular volume also increases and initially the stroke volume is maintained by the Frank-Starling principle. ... These factors include the afterload, the left ventricular to left atrial pressure gradient and the compliance of the left atrium, and the size of the mitral valve orifice during regurgitation.
Title: Re: Which cardiac variable may be affected in mitral valve prolapse? Post by: Anon12398 on Oct 14, 2016 so would the answer be c?
