Sinus tachycardia is a sinus rhythm with an elevated rate of impulses, defined as a rate greater than 100 beats/min (bpm) in an average adult. The normal resting heart rate in the average male adult ranges from 60–100 bpm and women 60-90 bpm. Sinus tachycardia refers to a faster-than-usual heart rhythm. Your heart has a natural pacemaker called the sinus node, which generates electrical impulses that move through your heart muscle and cause it to contract, or beat. Normal sinus rhythm typically results in a heart rate of 60 to 100 beats per minute.
