Heart Rate Variability
Is heart rate variability a good way to measure stress and are there at-home devices/software for doing it? (maybe chest strap-app combos)?
No: Heart rate variability is actually a sign of a healthy heart, not stress. Your heart rate should vary throughout the day, in response to a multitude of factors. Commercial heart rate monitors do measure HR accurately, and can be used to track your fitness level over time. Hope this helps! ...Read more
How could the level heart rate variability be an indicator of the level of sympathetic or vagal control?
It is: Our regular heart rate which is slower than the intrinsic rate is the balance between the sympathetic and vagal inputs to the sinus node at any time with the latter dominating.This causes beat to beat variation specially noticeable during respiration Parasympathetic activity is represented by reduced variation in time domain and dominance of hi frequency oscillations in the spectral analysis ...Read more
My heart rate variability on holter monitor showed the following: SDNN- 207, SDANN- 227, RMSSD- 75 & Triangular index- 59. Are these readings normal?
Biofeedback - which is more accurate for generalized anxiety, galvanic skin response or heart rate variability?
I get high 180 heart rate at night but woke up this morning with a heart rate of 36. What can cause such variability?
Arrhythmia: A heart rate of 180, given your age, is approaching the maximum heart rate that doctor's expect when doing "usual" activities (in this case, exercise) without an underlying disorder. If u get this heart rate while sleeping or resting, then u could have atrial fibrilllation (A-fib) or another arrhythmia. In the morning, ur heart compensates by slowing down to rest (the only way). See a cardiologist ...Read more
Acidosis.: Non-reassuring fetal heart tones include loss of beat to beat or short term variability. They are commonly used to monitor fetal status and determine timing/mode of delivery although they have an exceedingly high false-positive rate in predicting actual neurological impairment in the infant. They can be due to: acidosis; hypoxia; drugs; infection; sleep cycle; dehydration; anemia; thyroidopathies. ...Read more
Variability in care: Psychotherapy requires a relationship between humans -- not machines. Humans (including therapists) are variable in their skills and interests. Basic competencies must be assured through credentialing, but beyond that things may vary. You need to find a therapist with expertise in the areas you want help with. Other issues include insurance restrictions on timing and frequency of sessions. ...Read moreSee 2 more doctor answers
Does BP/HR variability matter? 9AM resting BP/HR avg is 119/78/59; but might be 138/88/49 then 115/73/65 next day. Swings hour-to-hour while at desk.
