Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: 29F, non-smoker with history of NSVT. Diagnosed in 2011. NSVT was then changed to PSVT in patient records without my knowledge until recently.Diagnosis would present with palps, lightheadedness and tunnel vision. It occurs randomly with no clear trigger.I had a new holter applied for rapid pounding heart with dizziness and angina.Holter findings were reported normal with low burden PVC and sinus tachycardia. (sinus tachycardia is expected culprit for rapid heart and associated symptoms)However, VT was also noted?https://imgur.com/a/S2rMmmEThe comment states AIVR. And Im just curious if this is actually AIVR or PSVT? Or something else entirely.I do have an appointment with Cardiology in a few weeks.. ### Response: Characterized as AIVR because rate is <110 with widened QRS.PSVT is usually in the setting of tachycardia so rate goes from normal to very high. Had a few more beats (like those shown) at a faster rate happened, it may have been called PSVT..
