The resting heart rate of an individual will vary depending on their age, body size,heart conditionsand medication use, as well as the temperature of the air around them. Emotions can also affect one's heart rate; for example, getting excited or scared can increase the heart rate. Getting ...
The hallmarks of a cardiac examination are cardiac rate, rhythm, sound and blood pressure. What is considered normal for each of these parameters will change from birth through puberty. Understanding these changes can help in clinical diagnosis. The rate ofcardiac contractionwill vary throughout the...
Calculating Heart Rate and HRV Parameters The measured values need to be converted into values that we can understand through some formulas and algorithms. The following time-domain parameters are defined as Standard deviation of Normal to Normal intervals (SDNN) (5) and root mean square of succes...
Yourheart rateis the number of heartbeats you have in a minute. Your heart rate depends on what you're doing at the time. So, if you're resting or relaxed, your heart beats slower, and if you're moving or stressed, your heart beats faster. Your body adapts to your energy needs and...
Recent studies have established that cardiac and respiratory phases can modulate perception and related neural dynamics. While heart rate and respiratory sinus arrhythmia possibly affect interoception biomarkers, such as heartbeat-evoked potentials, the
Although the annual mortality rate is higher in men, more women than men die of heart failure each year, and the clinical presentation of heart failure differs between men and women35.Therefore, more research is required to assess the different treatments available for HF between men and women....
one person's "vigorous" may be another's "moderate." Heart rate zone training tries to provide an objective measure of intensity by breaking it down into various zones. But heart rate can also be influenced bytemperature, medications and stress levels, which may affect readings during exercise...
heart rate and thermal conditions, many have reported heart rate variability at different thermal sensation levels based on the principle of thermoregulation. ... JH Choi,V Loftness,DW Lee - 《Building & Environment》 被引量: 32发表: 2012年 Study on thermal comfort of low-sweat and high-swea...
Restoring chronotropic competence in HFNEF patients with rate-adaptive pacing is currently being assessed in the RESET (Restoration of Chronotropic Competence in Heart Failure Patients with Normal Ejection Fraction) study. Finally, LA dilation and dysfunction (24); volume overload because of renal ...
Heart rate variability (HRV), which represents the variation of the beat-to-beat interval, is a simple and noninvasive method to evaluate ANS functions that influence cardiovascular systems. HRV assessments include time-domain analysis, e.g., the standard deviation of normal to normal interval (...
