Avatar n tn Biocom Technologies is the global leader in the development, manufacture and marketing of Heart Rate Variability products. The company was founded in 1996 as a Research and Development Company. Specifically, Biocom develops biomedical software and hardware products designed to monitor physiology for research and educational purposes.
Avatar m tn There has been experiments with different psychological and physiological measures, but it was consistently heart rate variability (HRV), or heart rhythms, that appear to be the most dynamic and reflective of inner emotional states and stress. It seems clear that the automatic nervous system and any negative emotions lead to increased disorder in the heart’s rhythms and in the autonomic nervous system, thereby adversely affecting the rest of the body.
Avatar n tn If this is a possible explanation for CHF and related cardiomyopathy, might it not explain why women have increased PVCs/PACs/heart rate variability/tachycardia associated with their menstrual cycles-a process that involves hormones,beta-receptors, and endothiliel cell responsiveness?
Avatar f tn Check your own heart rate at different times of day. When you wake up, after you take a shower, after you've gone up and down the stairs a few times. Is it the same every time? No. Are you unhealthy because of it? No. Heart rates aren't supposed to stay static. The body doesn't work that way. All those numbers are well within the range of normal. There is absolutely nothing wrong with that amount of variability.
Avatar n tn Hello to everyone. I have finally been able to post. I am 14 weeks pregnant with my first child. I rented a Doppler at 9 weeks and have been able to heart it ever since. I usually check on the baby's heart rate every night for a minute or so. I have noticed that my baby's heart rate has been considerably lower these past few days and I am concerned. The baby's heart rate is averaging between 135-145 BPM, when it used to be 150-160.
Avatar n tn A definition of normal would also include what is the heart rate variability, how quickly does it recover after exercise, etc. If you are worried, it is probably best to ask your doctor if everything is ok. Wikipedia has a well written article also. http://en.wikipedia.org/wiki/Heart_rate I hope this helps.
Avatar m tn If simply exercising, the variability in heart rate diminishes, with it only decelerating slightly when I exhale. Is this something to be alarmed about?
Avatar n tn Posted By rae on June 01, 1999 at 14:41:45 i recently made a trip to an emergency room due to mild chest pain and what felt like an irregular heart rate and they performed an ekg on me and said everything looked good. while at my doctor's office on friday i had a chance to look at the ekg results, it said "irregular sinus bradycardia." my doctor listened to my hearbeat and said the heart rate change upon inhalation is an arrythmia which is normal in young healthy hearts.
Avatar f tn Thats exactly what I mean, but, when it speeds up it seems to go rather fast.
Avatar f tn My average Heart Rate for the 24 hour period was 104. My family doctor also noted that the heart rate variability may be a problem. The heart rate variability was as follows. ASDNN: 37.4 sec SDNN: 100.3 SDANN: 92.2 RMSSD: 19.6. There is a bar graph that indicates the "minutes of tachycardia per interval" and most intervals (i am assuming an interval = 1 hour) have fifty or more minutes of tachycardia.
Avatar n tn The primary mechanisms of respiratory sinus arrhythmia (RSA) are understood to be the modulation of cardiac vagal efferent activity by the central respiratory drive and the lung inflation reflex, and the degree of RSA increases with cardiac vagal activity. Heart rate variability (HRV) is increasingly being used as an activity indicator of autonomic nervous system. HRV has also been shown to decline with the aging process.
Avatar n tn s heart rate you have to know what the heart rate ranges are, the average heart rate, and if she has appropriate heart rate variability. That can be accomplished by having your daughter wear a holter monitor for 24 hours. That can look for irregular heart beats as well. If a child has an abnormally elevated heart rate, but otherwise seems fine, as your daughter seems to be, then other things have to be looked for: thyroid abnormalities, anemia and catecholamine secreting tumors.
Avatar n tn Does anyone else's heart rate seem to go through cycles? There are days throughout the month where my heart rate stays around 79-86 during the day no matter what I do. Then things will suddenly change. My heart rate will be in the mid-to-high 90s just sitting. ????What's up with that???? If I walk around, just walk, it is in the lowish 100s and if I go UP or DOWN the stairs, it will be in the 125s. ??? Does anyone else have this happen to them?
Avatar n tn Heart rate is affected by both blood pressure and respiratory rate. Interestingly, when a person has autonomic failure, it is demonstrated by a LACK of heart rate variability, so at least you've proven you're not in autonomic failure! So that's a good thing. :-) I might be able to give a little more insight if you give your blood pressures over the time you are standing that go with the heart rates.
Avatar f tn Hi itdood, thank you for your comment. I didn't know about heart rate increase during REM sleep. I also didn't know about heart rate variability or HRV. I will research on it!! Thank you!! I really appreciate your comment and I love this site.....!
Avatar n tn What is a normal heart rate for a newborn. Is a resting heart rate of 69-79 dangerously low. Should the newborn be on a heart monitor? Should the parents seek a second opinion? Which hospitals in the Boston area are known for their newborn cardiac units, which one would you recommend to someone? Thank you. _ Dear Kerri, The normal heart rate in newborns ranges from 120-170 beats per minute.

Avatar n tn fast heart rate again

Avatar f tn No great swing today. Fairly normal; quite strange. period.
Avatar f tn Bad day today. Had another storm this morning at about 10:30. Climbed to the 130's, even low 140's. Had really to water the plants after too many days of neglect. HR did not abate; kept in the 130's, even lower 140's. Was too hot outside; came back to office, but HR still going too fast, around the 100's seated. In the afternoon, had another storm in the 100's, 110's peaking to 130. Rowed anyway, as I need to keep at it.
Avatar f tn Heart rate more settled today. Maybe because of period coming?
