In cardiology, what does "SVT" refer to?

In cardiology, "SVT" refers to Supraventricular Tachycardia. This condition involves a rapid heart rate originating above the heart's ventricles, specifically from the atria or the atrioventricular (AV) node. It is characterized by episodes where the heart beats faster than normal, which can lead to symptoms such as palpitations, dizziness, shortness of breath, or chest pain. Understanding this term is crucial for medical scribes and healthcare professionals because it helps in accurately recording patient symptoms, diagnoses, and treatment plans related to cardiac function.

The other terms provided do not pertain to standard medical terminology used in cardiology. Substantial vascular tonicity and supervised ventricular treatment are not recognized terms in the field, and surface velocity transthoracic may relate to imaging techniques but does not describe a cardiac rhythm disorder like SVT does.
