Detailed Answer:
Hello,

Welcome and thanks for your query.
I presume that she had no symptoms like fever or musculoskeletal pains.
Was the heat flash from the back to front along a nerve distribution? If so it can be from a nerve being stimulated. This can be from electrolyte abnormalities like a decreased ionized calcium level as can occur with increased breathing or anxiety.
Claminess of the skin is due to decreased skin perfusion and can be due to a fall in blood pressure or anxiety.
If symptoms persist it would be good to have her examined by a doctor and investigated if necessary.
Do get back to me if you have further queries.

Hello...my wife is 36 years old, 5 6 , 125 lbs., fit and athletic...while jogging/running on our treadmill, her heartrate will jump from 175/180 BPM to 210/215 BPM for a short period of time (maybe a minute or so) without changing her output (i.e. running pace)...I m confident the heartrate monitor is correct because it works fine on me. The BPM when I m using the treadmill monitor are consistent with a different heartrate monotor I use on a street bike. In addition to her heartrate spikes, I personally think her jogging BPM rate is not consistent (too high) relative to output. Do you see any of this to be a problem?

Hello. My normal heart rate is about 100 - 120 bpm. I had palpitations occasionally but I never went to see the doctor as I thought it was normal although they usually lasted from 5 to 10 minutes. Last year when I was 24 weeks pregnant, I had a heart palpitation (while I was resting) and my heart rate went up to 240 bpm. It was only after I got injected with adenosine (35mins later) did my heart rate went down to 120bpm. The doctors diagnosed me with an SVT. Due to that, I requested to deliver my baby through C-section. This year, I'm pregnant again and I still go for my scheduled appointments every few months with the cardiologist. Only now he does not think it sounds like I have SVT. This year I will deliver my baby normally but I'm still quite worried about my heart. My question is, if I don't have SVT, what kind of heart condition do I have? I still have palpitations sometimes, my heart rate is never below 100bpm, I always feel fatigued and chest pain and short of breath. Thank you.

My daughter has been fighting a cold. I thought she was over it then she woke up with a headache (which is unusual for her) on Saturday. She eventually took a nap and felt better when she woke up. She felt great all day on Halloween. She woke up yesterday with a fever which increased during the morning. It reached 103.1 but then decreased. I did not give her fever reducers. By the time we got to the doctor at 12:45, she was fine. She was only running 100 degrees and being her usual silly self. The doctor said to bring her back if she still had a fever in a few days and to send her to school today. The school sent her home with 102 degrees. She was hot, but seemed fine until about 20 minutes ago. Now she sounds very uncomfortable. She is saying that her heart hurts when she breathes. I can not hear anything in her lungs with my stethoscope, but I noticed that her heart rate is elevated - it seems to be about 140 BPM. She is 6 years old.
