Blood pressure ranges are categorized by the American Heart Association into five distinct levels to assist individuals and healthcare providers in assessing cardiovascular health. These ranges include Normal, Elevated, High Blood Pressure (Hypertension) Stage 1, High Blood Pressure (Hypertension) Stage 2...
Heart rate, blood pressure, lead II electrocardiogram (ECG) intervals, as well as conduction, refractoriness, and nodal function were measured. Placebo had no effect on any parameter. With the exception of prolonging the atrial refractory period, bidisomide had no effect on any parameter at the...
Only values of “healthy” reference cohorts were included. In particular, reference cohorts that included subjects with a disease or condition known to affect the measured parameter (e.g. hypertension and diabetes) were excluded. For publications that described population statistics (e.g., the MESA...

Luijkx found a balanced increase of LV and RV chamber volume in relationship in the athlete heart [51]; a large meta-analysis of the literature had a similar conclusion [49]. RV and LV systolic function is commonly characterized by ejection fraction, but this parameter is known to show the...
I2, Q, and the p value for Q for each parameter are also shown. Impact of training volume on biventricular size When athletes were divided into 4 categories according to training hours per week, a significant impact of training volume was demonstrated for RV absolute volumes. Indeed, as ...
(HRV) signal can be used as a reliable indicator of state of the heart. It becomes less random with the aging(less chaotic). This is evaluated by using various time domain, frequency domain and nonlinear parameters like SD1/SD2, ApEn, LLE αsand αl. Different ranges of non-linear ...
The entropy, which is defined as a term of physics, was considered to be a promising parameter in gated blood-pool study for indication of CRT.19 Random distribution in the dilated left ventricle with reduced contractility, which cannot be reflected by simple PSD and bandwidth, may fit the ...
