I am 61 years old, my blood pressure in the morning when I woke up in the morning was 137/99, heart rate 71. Second time was 126/93, heart rate 71. Third time was 134/89, heart rate 85. But after When I returned from exercise and rested for 15 minutes, I re-measured my blood pressure as follows: 1st time was 116/86, heart rate 86. Second time 114/86, heart rate 86. So the doctor asked me for blood pressure readings. Is it not stable?
