Hello and welcome to HCM,
Thank you for your query.
A heart rate
of 90-95 is still considered to be normal. These could be palpitations or some other cardiac presentation.
It would be best to consult a cardiologist
and get your ECG (EKG) and an echocardiography
done, to rule out any underlying conditions.
This presentation could also be normal, and just be a result of change in posture and a slight change in blood pressure or just stress
But, it is always best to discuss all new symptoms with your doctor who can also investigate it further.
I hope I have succeeded in answering your questions, you could write back to us anytime for further clarifications.
