I remain amazed at the ignorance people can display in their answers. Blood pressure is indeed determined by peripheral resistance. When your blood pressure is measured the cuff compresses an artery. As the "pressure" is released from the cuff there is a specific point at which the first spurt of blood passes through the expanding artery -- this is the "top" number (systolic value). The point at which your artery is again fully expanded during the compression will give you the "bottom" number (diastolic value). The higher the systolic value, the harder your heart is working as the blood is being forced through earlier, and at a higher value (measured in mm/Hg). Also, a high diastolic number can indicate hardening of the arteries. The artery is not able to expand as much, and is fully expanded sooner during the measurement, thus giving a higher reading.

I was diagnosed with high blood pressure last year after i pushed myself too hard physically, and i ve since been able to come off my meds by dieting and exercising. But i recently did an exercise that was too tough because i thought i could handle it, and the whole day after i felt unusually groggy and my systolic number was about 10 points below normal. Now that i ve recovered somewhat, my resting blood pressure is normal but it goes a bit higher than it should when i m excited or active, sometimes causing loud ringing of the ears or other symptoms. I try light exercises throughout the day but it seems like my heart is getting worn out easily, where i will get a heart rate in the 50 s sometimes or my systolic number will drop to below 110 and then my pr and bp fluxuate a bit higher throughout the day when i become active. I want to know if maybe you had some idea of what could be wrong or how to know when my exercise is too much because in contrast to exercising a fair bit before, now it mainly consists of just my daily activities and if the bar s been lowered that much i m just done. 20 year old male, scared that his new life is already over. 3 months til cardiologist apointment, primary doctor doesnt seem very concerned with my problems. I used to actually have a life.

I was hospitalized yesterday for very high bp (avg 190/115), did an ecg and had abnormal t-wave (inverted). They gave me a shot of nitro and iv injected beta blocker...a few hours later, bp returned to normal (128/82 avg). They released me, but I m going for a stress test in the next couple of days. Today my bp was high again this a.m., but is now averaging 90/60 or less, is this a sign of something serious going on, and should I get back to the hospital? I am a calm person, I d just rather be safe than sorry.

In the last few weeks, I have started having like a hot flash in my neck and checks; almost like I m blushing. I suffer with lack of energy, depression and anxiety (grieving loss of spouse of 30 years and mother) but this is a new situation. Currently being treated for high blood pressure with HCTZ in the morning and Norvasc at night. I take vitamin D (5,000 IU) daily along with CoQ10 and Xanax PRN. I m 64 and thought I had gone through menopause already. Could this be the anxiety/depression and if so, what supplement could I take to help. I have no insurance so medical testing is not an option at this time.
