Hi. Sinus tachycardia is sinus rhythm with a rate of > 100bpm.
Appropriate sinus tachycardia can result from:
Exercise
Anxiety
Alcohol / caffeine use
Drugs (e.g. beta-agonists like dobutamine)
Inappropriate sinus tachycardia can result from:
Fever
Hypotension
Hypoxia
Congestive heart failure
Bleeding
Anemia
Hyperthyroidism
Cardiomyopathy (with reduced left ventricular function and compensatory tachycardia)
Myocarditis
Inappropiate sinus tachycardia is rare and 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.
