rate is called a pulse deficit. Such a deficit occurs when a cardiac action does not affect the circulation (e.g. extrasystoles, atrial fibrillation) or the blood flow at the site of pulse measurement is unaffected by the heartbeat (peripheral disturbance, e.g. peripheral arterial occlusive ...
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 ...
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 human heart can beat more than 115,000 times a day.5You might not pay any mind to the rate at which your heart beats, but how it varies can tell you a lot. Read on to learn what normal HRV is and what it can tell you about your health. ...
Cardiac output is defined as the amount of blood your heart pumps. Learn about the normal output rate, how it's measured, and causes of low cardiac output.
We give an example of the dominant influence of respiration on heart beat dynamics, which shows that observed fluctuations can be mostly explained by respiratory modulations of heart rate and blood pressure (coefficient of determination: 96%). Therefore, we recommend reformulating the following initial...

Summary measures of heart rate variation describe those aspects of heart rate change that can be averaged over relatively long periods of time. We examined the postnatal maturation of a dynamic feature of cardiac rate--the dependency of each beat-to-beat change in cardiac interbeat interval on ...
