I'm 35. I Am 6'3" Tall, Weigh 235, In Good

I'm 35. I am 6'3" tall, weigh 235, in good physical shape. I do have high blood pressure and my family has a history of heart disease. lately I have been feeling fatigued, and earlier this evening I started experiencing chest pains that seemed to start from my abdomen and consume up through my chest and upper body and give me a headache, then they just go away, but I still feel physically uncomfortable. I have a blood pressure wrist cuff to monitor my pressure. I have checked it the last 3 times this has happened. 1st was 141/100 with a HR of 70. 2nd was 135/99 with HR of 72. last was 148/104 with HR of 69. my normal resting HR is usually around 55.
