Bradycardia. Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block. Resting heart rates of less than 50 BPM are ...
The pulse may vary due to exercise, fitness level, disease, emotions, and medications. The pulse also varies with age. A newborn can have a heart rate of 100–160 bpm, an infant (0–5 months old) a heart rate of 90–150 bpm, and a toddler (6–12 months old) a heart rate of 80–140 bpm.
A medical monitoring device displaying a normal human heart rate. Heart rate (or pulse rate) [1] is the frequency of the heartbeat measured by the number of contractions of the heart per minute ( beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
Mental health conditions, such as post-traumatic stress disorder (PTSD), social phobia, social anxiety disorder and panic disorder. ... Increased heart rate. Upset stomach. Sweating.
Heart rate variability ( HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. Other terms used include "cycle length variability", "R–R variability" (where R is a point corresponding to the peak of the QRS complex of the ECG wave; and R–R is ...
Athletic heart syndrome ( AHS) is a non- pathological condition commonly seen in sports medicine in which the human heart is enlarged, and the resting heart rate is lower than normal. The athlete's heart is associated with physiological cardiac remodeling as a consequence of repetitive cardiac loading. [3]

The green line shows the heart rate variations averaged over several breathing cycles. It is clearly visible heart rate increase-decrease trend which is typical of RSA. RSA as a vagal tone estimator. Respiratory sinus arrhythmia is frequently used as a noninvasive method for investigating vagal tone, in physiological, behavioral, and several ...
