What Does it Mean to Have Sinus Tachycardia?

Sinus tachycardia is a condition, in which a person experiences faster heart rhythm than what it should be in the usual case. This article discusses what it means to have sinus tachycardia. Our heart generally has a natural pacemaker, which is usually called a sinus node. The function of the sinus node is to generate the electrical impulse, which in turn moves through the muscles of the heart and cause the heartbeat. Generally, the electrical impulse generates at a rate of 60 to 100 beats per minute. This normal condition is called normal sinus rhythm. Sometimes this rate is more than 100 beats per minute and such a situation is called sinus tachycardia.
