2 leaky valves

[CTucker225]

For the past few months I have been wearing my heart rate monitor while taking kickboxing, boot camp classes etc, and my heart rate elevates quickly (up to 205 during kickboxing).  Anyway I went to see the cardiologist and today I was told that I had 2 leaky valves while they were doing my echo, then during my stress test my heart rate got up to 170 at 6 minutes so they took me off and did a follow up echo.  Anyway my question is with 2 leaky valves and my heart rate acting crazy with exercise could the leaky valves be the problem?

I go back to the cardiologist on Nov. 3 to get the results from the holter monitor.

Thanks

I am 30 so they told me that the absolute max I should get my heart rate is 190 and during any type of aerobic class (step, spin, kickboxing, and even going up and down my stairs to grab stuff)  I will hit 195 within 10 minutes.

Mild leakage is usually considered medically insignificant ...not an uncommon condition with no progression.

Tachycardia can originate from the right atrium (upper chamber) sinus node (natural pacemaker of electrical impulses), impulse pathway blockage, etc. can cause an irregular heart rate...sinus node and/or electrical impulse conduction problem is almost always the source if abnormal.

With exercise the target heart rate can safely be 90% of 220 minus age, 205 hr may be too high unless you are very young,  and 170 is not an unusual if your age is below 45.  The 170 heart rate may be incidental to an abnormality produced with monitoring equipment and cause tor discontinue.
