It's called sinus tachycardia - (Latin: tachycardia sinusalis) - to accelerate the physiological heart rate (the so-called sinus rhythm, which is transmitted by the sinus node), above 100 beats per minute. Diagnosis of sinus tachycardia condition is the presence of normal heart beats, and the only variation is observed as acceleration of the rhythm. Sinus tachycardia is the normal reaction of the body when there is an increased metabolic demand or the need to maintain or increase blood pressure. This occurs in situations of physiological and pathological conditions such as: stress; stimulants such as caffeine, nicotine, alcohol; effort; heart failure; dehydration; shock. Sinus tachycardia, being a physiological reaction, remains under the control of homeostasis. When it comes to out of control - there is a condition called inappropriate sinus tachycardia The speed of shares is typically in the range 100-160 beats per minute, and the body begins to feel the heart beating too fast, you may get increased fatigue, or even fainting may occur.
