Tachycardia is an abnormal rapidity of heart action that usually is defined as a heart rate more than 100 beats per minute (bpm) in adults. In children, the normal heart rate is age dependent, and the definition of tachycardia varies, as shown below.[1, 2]
Age 1-2 days - 123-159 bpmAge 3-6 days - 129-166 bpmAge 1-3 weeks - 107-182 bpmAge 1-2 months - 121-179 bpmAge 3-5 months - 106-186 bpmAge 6-11 months - 109-169 bpmAge 1-2 years - 89-151 bpmAge 3-4 years - 73-137 bpmAge 5-7 years - 65-133 bpmAge 8-11 years - 62-130 bpmAge 12-15 years - 60-119 bpmNextPathophysiologyThe heart is innervated primarily by the vagus nerve and the sympathetic ganglion. Pain sensation travels through afferent fibers associated with the sympathetic ganglia. In most patients, the sensation of a normal heartbeat is not felt. Some children may complain of palpitations or rushing or pounding in the ears.
