i think most of you here know me and my condition but in case you do not,let me quickly say that i am a 31 year old male and i have problems with high blood pressure,tachycardia,shortness of breath and chest pains. i need to lose a lot of weight and doctors have suggested walking more. today i decided to walk 4 blocks downhill at a slightly fast pace. after 3 blocks,i started to become dizzy and gasping for air and i had a minor headache with tightness in my left arm. i went into a pharmacy that was right there and decided to put my hand into the cuff and measure my vitals. i sat and relaxed and to my shock,my numbers were 218/98 for bp and my pulse was 151. i got worried and took the bus home and by the time i got home,i put on my polar monitor and my heart rate was 164. i was too nervous to measure my bp. i ended my loading up on beta blockers and sitting down for 2 hours. i still felt dizzy and my heart rate was 103 after a lot of atenolol. can anyone here tell me,are my vitals dangerous? can i suffer a stroke? how can i lose weight if i am so exercise intolerant? thanks.
