I've taken my wife's blood pressure about 8 times the past few days and am concerned over the heart rate. They are as follows; 110/82 over 154, 121/93 over 158, 127/98 over 135, 140/105 over 133, 93/69 over 127 last night and 124/83 over 170 this morning. Its that third figure that has me very concerned. What would you suggest ?Thanks, Mr. Mason
