TachyBrady symptoms - heart rate increases with standing

[AJY]

I am a 49 year old female.  At 30 I was told after an echo that I had MVP with mild regurgitation.  I have had numerous palipations, heart racing etc.  I also have had high BP since I was pregnant with my son and had toxemia (17 yrs ago).  Recently, I began noticing my heart rate was occasionally in the high 40's range when checking my BP.  When I went to a new doctor, he did an EKG and said it seemed okay, except showing bracardia.  He changed my BP meds to Diovan, and when I returned, it seemed to be doing better.  I also had another echo and the report said I did not have MVP (after about 6 others said I did) with regurgiation.  I joined a gym in Feb. and have lost 20 lbs. (Still have a ways to go)  I noticed my HR was again dropping at times in the 40's, and also still have the palipatations at different times.  After a follow-up appt., the doctor wanted me to wear an events monitor.  The report from it stated that the monitor showed episodes of sinus tracycardia with 150 HR, and an episode of SVT with 170 HR.  There were no premature contactions noted, but sinus arrhythmias.  I noticed at least 4 out of the 10 events recorded, that the HR was high 40s.  There was no notations in the report on this.  I also noticed and have confirmed on several occassions, that my heart races merely by standing up.  I noticed an increase of 30 beats the other day when I slowly stood up with the BP machine.  I have to go back to the doctor shortly to get his report.  I would like additional opinions as to the situation before I go to help make a decision about any treatment, if any.  Can this be dangerous, or if it's bearable, would it be okay to just go on without any treatment?  AJY

No major symptoms - just tired feeling the majority of the time. AJY

If you aren't having symptoms, heart rates in the 40's are fine.

What about the low HRs?

If you can live with it, you might not need treatment but it depends on what the SVT was.  If it was sinus tachycardia, I wouldn't do any further treatment.  If it was something else that might be treatable, other options may be available like medications or ablation.  

There is probably not much you can do about the sinus tachycardia and the increased heart rate with standing.  Many people have this same heart rate issues but there is honestly not a great "treatment" for it but it really doesn't cause any harm and doesn't need treatment unless the treat is to reduce symptoms that it may cause.

Does this answer the question?
