Can mitral valve prolapse be a cause of svt?

Not likely: Mvp typically doesn't cause too many problems in an otherwise healthy person. If there is an underlying heart problem or other disease process at work, then all bets are off. While it may be associated with it, the mvp isn't likely to be the direct cause.

Probably not directl: Mitral valve prolapse is a description of how the mitral valve closes. It can be associated with a leaking mitral valve. If the leak is large enough it can cause parts of the heart to expand and dilate. This can predispose you to develop all sorts of rhythm issues. But most who have prolapse don't develop svt's because most do not have any significant leak.
