ECG Findings: 1. Atrial Fibrillation with a Rapid Ventricular Response. 2. Left Bundle Branch Block. Any tachycardic rhythm with a left or right bundle branch block that is NOT ventricular ...

Supraventricular tachycardia (SVT) is a very rapid heartbeat (usually between 151 and 250 beats per minute, or BPM) and can cause a number of serious health issues. It’s seen in just over 2 out ...

But SVT is a fast heart rate that begins in your atria due to abnormal electrical connections in your heart. Both AFib and SVT are diagnosed with an electrocardiogram (EKG).

If the ECG shows SVT, a doctor may recommend an electrophysiology study to determine the type and cause. This test takes place in the hospital and requires sedation.

For many years, cardiologists and other experts have tried to find reliable methods of distinguishing between VT and SVT-AC on the basis of ECG criteria. Have we found one yet?

Ventricular tachycardia, or V-tach (VT), and supraventricular tachycardia (SVT) are two types of tachycardia. The term “tachycardia” refers to a heart rate of more than 100 beats per minute.
