Should I be concerned with my Holter Monitor results?

I am a 59 year old female - I was diagnosed with having a Left Bundle Branch Block a few years ago.  About a year ago I was diagnosed as also having a Mitral Valve Prolapse with regurgitation.  In the last few months I've begun having (or become aware of having) palpitations.  I don't have any other heart symptoms other than being tired a lot.  When I mentioned them to my new primary care person (a nurse/practioner) she suggested I do a 48 hour Holter monitor.  The results were: 1.  Accompanying EKG shows normal sinus rhythm, possible left atrial enlargement, left axis diviation, left bundle branch block.  PR 174, QRS 136 ms.  QRS is increased and is related to the left bundle branch block pattern. QTC 472 milliseconds.  2.  The underlying rhythm throughout the 48-hour period is sinus with rates between 67 and 160 beats per minute.  Average is 93 beats per minute.  3.  Beats in tachycardia greater than 100 beats per minute occur for 26% of the total number of beats counted and at no time is the heart rate less than 60 per minute.  4.  No significant pauses seen.  5.  Fixe isolated PAC's seen.  No atrial couplets or atrial tachycardia were seen.  6.  185 isolated PVC's seen.  No ventricular couplets or ventricular tachycardia were seen.  The PVS's are predominantly monomorphic in appearance.

My main question is this:  My mitral valve problem is excluded from my insurance until Sept. 1st. as a pre-existing condition.  Can I safely wait until Sept. 1st to see a cardiologist?  My nurse/practioner feels I can wait.  Any thoughts?

It is always difficult to say if something is safe just by history alone on email. Having MVP with regurgitation should (and needs) to be followed regularly, usually with an echocardiogram to follow the degree of regurgitation as well as progression of any structural heart disease (decreased LV function, hypertrophy, or dilation). The results of your holter monitor show that there is some underlying conduction disease (LBBB) but also needs to be in the context of any accompanying symptoms. The safest advice is that if you are having any concerning symptoms (and especially worsening symptoms) you should be seen by a physician for further evaluation.
