What is the EKG difference between SVT and ST?

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.
