Variability In Fetal Heart Monitoring
My heart rate variability on holter monitor showed the following: SDNN- 207, SDANN- 227, RMSSD- 75 & Triangular index- 59. Are these readings normal?
It may vary: It would be better to look at the rhythm strips. Consider Virtual consult with me I will be happy to look at those strips. ...Read more
What device monitors only anxiety and not excitement? Wristbands that monitor heart rate variability can't tell the difference
Spire: One device is called Spire. It clips onto your belt or bra. It measures your breathing and you can watch your breath wave on your iPhone. When you get anxious you tend to breath faster. It syncs with your iPhone. It also measures your activity level. It comes with meditation instruction. Available on Amazon. See://bit. Ly/28W8bpB ...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
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
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
Apple Watch measured my average Heart Rate Variability at 25ms. What does this mean? What is a healthy measurement?
My fitness tracker measured my Heart Rate Variability (HRV) at an average of 24ms. Is this too low? Should I be concerned? My resting heart rate is 72.
Safe: Your numbers are great for your age, especially if you are active. ...Read more
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
Biofeedback - which is more accurate for generalized anxiety, galvanic skin response or heart rate variability?
You shouldn't: Fetal heart rate monitoring should be done by trained professionals in real time for specific indications typically in some tpye of health care facility. ...Read more
I went at 16 weeks and they had trouble finding the fetus heart beat is this normal or should I be worried I bought a heartbeat monitor & nothing ($24?
No: It can be difficult to find the fetal heart rate when it is little, and it is nothing to be worried about. In 2-4 weeks you should be able to feel fetal movement and that should be reassuring. ...Read more
See ACOG guidelines: Maternal-fetal medicine or OB doctors or nurses spend lot of time looking at fetal heart monitoring tracings to see if there is a regular and normal heart rate, typical variability, absence of decelerations. They might order intermittent monitoring unless high-risk mom or abnormalities that can be associated with fetal problems. Parents should feel free to ask if continuous is needed. See my guide. ...Read more
Evaluation of FHR: Maternal-fetal medicine or OB doctors or nurses spend lot of time looking at the heart on ultrasound and fetal heart monitoring to see if there is a regular and normal heart rate, typical variability, absence of decelerations. They might look if normal pregnancy, if high-risk for mom, or if abnormalities that can be associated with chromosomal or other problems. Parents should feel free to ask why. ...Read more
Often: If the arrhythmia is intermittent, it may be difficult to detect with weekly monitoring. Most of the significant fetal arrhythmias are sustained and should be detected by an examination that includes an assessment of fetal heart rate and rhythm. ...Read more
See ACOG guidelines: Maternal-fetal medicine or OB doctors or nurses spend a lot of time looking at fetal heart monitoring tracings to see if there is a regular and normal heart rate, typical variability, absence of decelerations. They might order internal monitoring if high-risk mom or if abnormalities that can be associated with fetal problems. Parents should feel free to ask if it is needed. See my guide link below. ...Read more

Hi, I am 7 weeks and 4 days pregnant I brought a fetal heart rate monitor am I suppose to hear my baby heart beat on both sides of my uterus?
No: No, is probably too early too hear at all. Try again at 10-12 weeks ...Read more
If I took indoethacin in my last weeks of pregnancy, should the fetal heart rate be monitored on a daily basis?
Depends: Indomethacin taken frequently over a long period of time can cause a transient change in the fetal heart circulation (in doctor speak it closes the ductus arteriosus). Small doses for only a few days, which is usually the only thing we would do, is not particularly dangerous. Check with your doctor on why you are taking it and whether monitoring is needed. ...Read more
Ecg monitor: We generally monitor not only heart rate but heart rhythm. This identifies rhythm disturbances which if present could disorder the state of perfusion of the body and/or threaten the life and well being of the patient. ...Read more
Records rhythm: You wear a device that records your heart rhythm - used for diagnosing heart rhythms disturbances. The duration can be 24 or 48 hours (holter), 30 days (event monitor) or up to 3 years (sub-cutaneous loop recorder). ...Read more
Like an EKG: A holter monitor is basically a 24-hour-long ekg. It is used to monitor people for arrhythmias when a normal ekg isn't able to catch it due to its short length. The doctor will be able to read the ekg strip and look for skipped beats, irregular rhythms, or sites generating extra electrical signals. The doctor can also look at your diary to see if what you are complaining about correlate with ekg. ...Read more
Telemetry: For inpatient ambulatory patients, electrodes are taped to the chest and a transmitter box is attached to the trunk area. The heart rhythm recording is then transmitted wirelessly to a monitor at the nurses station. Bedside monitors don't allow the patient to walk about the ward freely. Other set ups allow the patient's heart rhythm to be recorded in a gadget strapped to the body. Finger styles. ...Read more
ECG: The waves on an ECG are called p-waves qrs complex and t-waves. The r to r interval is the distance between the R waves in successive beats. The distance is evaluated to measure the heart rate and to evaluate how regular the rhythm is. ...Read more
Yes: If you have been set up for monitoring for arrhythmias, it would be best to wear the monitor around the clock. ...Read more
None: Loop monitors cannot distiguish specific arrhythmias. They are capable of determining heart rate and can be programmed to record when the heart rate is above or below thresholds that are programmed at the time the monitor is placed. The recording is reviewed by the interpreting physician to define the specific arrhythmia. ...Read more
Possibilities: One common reason is if you have an irregular heart rhythm like atrial fibrillation. Other possibilities are technical: fresh batteries? Correct positioning? Good contact? Does it work on other people? If not, it may be defective. Has is ever worked on you? If so, what's changed? If it's never been accurate, it may not be a good unit - i'd advise an arm cuff if you decide to replace it. ...Read more
Fetal Monitor: For non medical people, the best way is place the monitor below the umbilicus and sweeps on either side of the lower abdomen until you hear heart beat. Whereever you pick up heart keep the monitor there. ...Read more

In short, no: Your body generally does an excellent job of regulating your core temperature, so it's not something you need to be concerned about. Heart rate is also highly regulated but varies much more widely for many reasons (like when we're startled) so it's not a reliable indicator of core temperature. ...Read more
Would a 24 hour heart monitor be able to tell if someone had POTS, or at least show warning signs?
BP monitor.: A 24 hour blood pressure monitor may help reveal the daily postural changes in blood pressure that may be suggestive of POTS. If used, a detailed diary of the day's activities and symptoms must be logged so that events and symptoms can be correlated with blood pressure changes. ...Read more
Heart palps getting worse. Wore monitor for 2 days last wk. Heard nothing. Palps lead to heart attack?
Palpitations: Benign palpitations usually don't lead to a heart attack. There are monitors that can be worn for upto a month or a week if needed to capture the extra beats. Again, most of these are not life threatening and can be controlled, but first the monitor needs to identify and capture the arrhythmia. ...Read more
