I Have Been Taking Lisinapril For My High Blood Pressure

I have been taking lisinapril for my high blood pressure and hydroclyocide for about 6 years sorry about my spelling. The other day I went to a doctor for a physical and she game be an EKG I have never had an EKG and she said she did it to check out my heart my old doctor never game me an EKG. So my EKG was abnormal Lower valve not performing properly, so I have an appointment with Cardiologist on Sept 1...I have been recording my Blood Pressure for the last 5 days and it is ranging from 125/83 to 117/77 with Heart rate in 70's and as low as 59. So should I be concerned because I have always been with a heart rate of 80's and 90's while taking lisinapril. I have acquire a heart flutter within the last 3 weeks and wish I could see the Cardiologist sooner but there is no open appointments.
