Sinus arrhythmia refers to the normal increase in heart rate that occurs during inspiration (when you breathe in). This is a normal response and is more accentuated in children than adults. Sinus tachycardia refers to a fast heartbeat (tachycardia) because of rapid firing of the sinoatrial (sinus) node.
Figure 5-2: A normal sinus rhythm. Often times, an arrhythmia is described by saying the underlying rhythm and adding to that anything abnormal (e.g. sinus rhythm with first degree heart block). If any abnormalities exist, do not include the word normal when designating the underlying rhythm.
