That is too high (tachycardia). You should strongly consider going to the ER this morning, if your cardiologist isn't available (as in "get dressed and go").
They can probably get you back out of there fairly quickly, as most people respond to treatment. It's likely not more than sinus tachycardia, but that is very wearing on the heart, and they can check right then whether there's something else involved as well. If they give you any prescriptions, make certain your doctor is made aware of them as soon as possible on Monday, or through his answering service today.
Temporary issues such as this do occur, especially early in the recovery. Do get it taken care of, but don't let yourself get stuck with a permanent fix for a temporary situation.
Best wishes,
