What is the EKG difference between SVT and ST?

submitted by Jess from Houston, Texas on 1/28/2013


by Texas Heart Institute cardiologist, Maher M. Nasser, MD  

Maher M. Nasser, MD ST may mean sinus tachycardia (fast heart beat up to 150/min). This could happen with exercise, jogging and other activities. SVT means supraventricular tachycardia, usually sudden onset where the heart rate may reach more than 200/min. This is usually a serious situation where you need to see your doctor.
