A congenital cardiovascular lesion is rarely signaled by a disturbance of the heart rate or the heart rhythm. Congenital cardiac disturbances are varied and may involve almost all components of the heart and great arteries. Some may cause death at the time of birth, others may not have an ...
They also reported that these missing heart rate values were higher in the first minute of exercise (between 20 and 40% of RR intervals), particularly at higher intensities of exercise. In our data, however, we did not find more missing beats in the stress stage compared to the relax ...
For most healthy adults, a normal resting heart rate is between 60 and 100 beats per minute. Children tend to have faster heart rates, while those ofathletesmight be lower. You can check your pulse most easily at your wrist or on the side of your neck. If you need to raise or lower ...
On standard electrocardiogram (ECG) PQ interval is known to be moderately heart rate dependent, but no physiologic details of this dependency have been established. At the same time, PQ dynamics is a clear candidate for non-invasive assessment of atrial abnormalities including the risk of atrial ...
A system for determining the heart rate in response to an electrocardiogram (EKG) signal that has been filtered by performing an autoregressive analysis, low-pass filtered by performing a digital filtering function, and the rate determined by utilizing a digital peak detection technique. In a heart...
In terms of heart rate, this means that a lower heart rate was associated with a bigger heart rate reflex response to the tilt and more variability in rate. Table 2. Group characteristics Group Sex (M/F) Gestation (wk) Birth weight (g) Non-smokers' infants (n ϭ 34) Smokers' ...
Means of reducing artefact are discussed, as we ways in which heart rate monitoring by radio telemetry is being used in the routine assessment of orthotic treatment of paediatric patients and the development of new orthotic devices. 展开
in sinus rhythm during the manual assessment indicating a very high positive predictive value of MEANS which was also demonstrated in earlier work [21]. RR intervals between 2 adjacent normal beats were used to compute the mean heart rate and time-domain indices of HRV; SDNN and RMSSD. Moreov...
Their method requires the continuous monitoring of heart rate signals over the Internet. Later, the signals are processed by means of a continuous wavelet transform in order to recover the local features of HRV in the time-frequency domain. Wang et al. [84] presented a pattern recognition ...
HR—heart rate measured for a given student at a given time; HR_AVG—average HR of the given student (see Table1); HR_Diff—the difference between the average HR of a student (HR_AVG) and the currently measured HR of the student (HR); ...
