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.
Not to be confused with Sudden cardiac death. Sudden arrhythmic death syndrome (SADS), also known as sudden adult death syndrome, sudden unexpected/unexplained death syndrome (SUDS) or sudden unexpected/unexplained nocturnal death syndrome (SUNDS), is a sudden unexpected death of adolescents and adults, mainly during sleep.
