independent component analysis; heart rate variability; heart rate; particle swarm optimization algorithm1. Introduction Heart rate and HRV are important vital signs. Clinical studies have confirmed that heart rate is closely related to the occurrence and prognosis of cardiovascular diseases (such as ...
Heart rate vs. pulse rate While the two go hand in hand, they are different. Your heart rate is a measure of the number of times yourheart beatsin a minute. With each beat, your heart squeezes. That creates enough pressure to push blood out of your heart to the rest of your body ...
and vice versa31. This influence is most readily apparent in the case of the effect of breathing on heart rate—the increase of heart rate during inspiration and its decrease during expiration
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 ...
The heart rate (HR) is defined as the number of heartbeats per minute. The discrepancy in the time intervals between consecutive heartbeats (interbeat intervals (IBIs)) is considered heart rate variability (HRV). The autonomic nervous system (ANS), a rudimentary nervous system component, regulates...
Nonetheless, physicians say that they look at the collective data and a clear picture emerges: that the salt, sugar, fat and processed foods in the American diet contribute to the nation's high rate of obesity, diabetes andheartdisease. ...
High heart rate (HR) predicts poor outcome in patients with HFpEF and sinus rhythm, but does not apply for those in atrial fibrillation, as shown in a post hoc analysis of the I-PRESERVE trial [72]. These findings were supported by a sub-analysis of the CHART-2 study, in which elevate...

Kronburget al. conclude that atrial pacing minimization in patients with sinus node dysfunction does not reduce the incidence of AF. Programming a base rate of 40 b.p.m. without rate-adaptive pacing is associated with...
