Sinus Tachycardia EKG Reference
Sinus Tachycardia is characterized by a pulse rate of more than 100 beats per minute in adults. The electrical signals originate in the sinoatrial (SA) node. Appropriate sinus tachycardia can result from exercise, alcohol or caffeine, drugs and anxiety.
Inappropriate Sinus Tachycardia is fairly rare. It can result from hypotension, hypoxia, congestive heart failure, bleeding, cardiomyopathy, myocarditis, anemia and fever.
