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.
