Inappropiate sinustachycardia is characterized by tachycardia at rest and exaggerated acceleration of the heart during physiologic stress. The mechanism leading to an exaggerated response of the sinus node to minimal physiologic stress is incompletely understood. | Inappropiate sinustachycardia is rare and characterized by tachycardia at rest and exaggerated acceleration of the heart during physiologic stress.
