i would think so...
this past week i've been having shortness of breath, to the point of hyperventilation at times...
my heart also hurts, or feels uncomfortable.
i hesitate to go on for the heart discomfort because i'm also depressed and in that state its hard to know if its just depression or if my heart REALLY hurts. ya know? anyways...
i'm so short my arm is pretty much at level withm my heart on the machines ;P
and i'm a pro on those machines, from waiting for mommy at the grocery store.
:/
i even know to test over and over on different machines at different times in different conditions. gah.
its def. 100/70-100/75
