Is it normal for panic attack to cause bp to go up to 127/81 pulse 113 then go down to 100/67 pulse 84? my normal is 110/74

YES: BP might fluctuate up and down according to patient situation, being emotional or physical Persistence of abnormal Blood Pressure warrants investigations to look for a cause

Yes: That would be expected. These are relatively minor fluctuations. I would not worry about the heart ate and blood pressure as much as addressing the anxiety or the reason for the panic attack.
