Extreme elevated heart rate with normal exertion - standing, walking

[Pastorphil]

My daughter-in-law is experiencing unexplainable extreme heart rate elevation with normal exertion such as walking or standing from a seated position.  Emergency room personnel recorded a jump from 98 BPM to 130-150 BPM upon standing from a seated position.  Subject is 20 years old and in good health.  Symptoms started shortly after eating breakfast on a cruise ship. Cruise ship medical personnel diagnosed anxiety as a possible cause, but hospital ultrasound and CBC discovered nothing significant.  Yet the condition persists even when subject is under influence of doctor prescribed Xanax.  What conditions might be causing this problem?

I have been suffering from chronic diarrhea since April. It has been so bad that I thought I had fecal inconvenience. When I went to the hospital, my heart rate was 170 standing and 145 sitting However, my blood pressure was kind of  low. The symptoms in the past two weeks now include shaking weekness and labored breathing. When i got my lab results from my hospital visit. There was a note at the bottom regarding my gfr being 60. I dont know what is going on but i haven't been out of bed in two weeks, cause to taking a shower  leaves me winded and dizzy.

Try taking an iron pill. Had same symptoms from taking laxatives. It also gave me panic attacks.

How are you doing now? I am 2 months post ablation and experiencing higher standing HR and skipped beats. Had 6 a-fibs during the first 2 weeks but nothing since " Knock on wood"

I am a 41 year young female....I experienced a perforated bowel about a year and a half ago, which required an emergency small bowel resection.  Since then I've had continuous abdominal pain.  My doctors started to notice my heightened heart rate within the past four months....My GI specialist performed a colonoscopy and concluded that I have IBS, and says the pain of my IBS is increasing my heart rate...Does this sound normal? My resting rate is almost always 100-110...immediately rising as I get up to anywhere from 120-145....my GI has referred me to UCSF, I'm just completely nervous

My heart rate goes from 60 sitting to 99 standing ,or 70 sitting to 109 standing  and I feel heavy palpitations in my chest.  My physical therapist said it should only go up about 10 points. I am 63 and have diastolic dysfunction stage 1 but the heart dr didn't say the diastolic dysfunction was causing the high high rate. I do have atrial fibrillation but that only happens once every 4 days. I also get shortness of breath when I stand. I was low on morning cortisone level 2  yrs ago but my afternoon level was ok. I ad shortness of breath then but now it's getting worse. If I walk around it goes up to 132 or higher. Then the nurse practitioner at my heart dr office tells me I have to get down my heart rate but doesn't tell me how to do that. I have been on a low cal diet for 5 months. Could that make my fast hr worse? I work out on an exercise bike 2 hrs a day getting my heart up to 115. If I walk on a treadmill the hr goes  too high which is why I switched to the bike. I am really struggling with this. It is affecting my whole life. I couldn't keep taking the prescription medicine cuz I couldn't tolerate it's affects of making me feel like I had been run over my a truck. It lowered my heart rate to low.
