My heart rate can be reduced or increased by Parnate. There are apprently two different contexts.
The acute and longer lasting anxiety attacks I experience when I am not taking Parnate seem to raise my heart rate as is expected. At times I am in a constant state of heightened anxiety when not on Parnate, which is bourne out by a resting heart that is above 100 or 115.
But also postural hypotension seems to increase heart rate, although Parnate will reduce or eliminate the rise in heart rate that is apparently due to the anxiety mentioned above.
Even though I am more relaxed my blood pressure is more unstable. I have noticed that low blood pressure if related to Parnate use, is correlated to a higher heart rate.
When I first get up after lying down, if I take my resting heart rate as quickly as possible it will be very high, then will drop as soon as I have been seated for a few minutes. Standing after sitting produces the same result.
I should mention that I never took my pulse (heart rate) until two years ago when I had bypass surgery, and that I am on Lopressor (a beta blocker) to control blood pressure and heart rate. But even while taking the Lopressor both of the above phenomenom occur.
Unfortunately the Lopressor also leads to a lower blood pressure when combined with Parnate than it otherwise would, but my cardiologist says I should take it anyway. So I live with a kind of constant sensation of postural hypotension for hours at a time, although not to the point of passing out.
