Atrioventricular reentrant tachycardia. Atrioventricular Re-entry Tachycardia (AVRT) is a type of paroxysmal supraventricular tachycardia (PSVT) caused by accessory pathways. It involves a re-entry circuit between the AV node and the accessory pathway. There are two types: orthodromic AVRT (narrow complex rhythm) and antidromic AVRT (wide complex rhythm). Coumel’s sign helps differentiate between orthodromic AVRT and AVNRT. In typical AVNRT, retrograde P waves occur early, while in AVRT, they oc

In managing a patient with Paroxysmal Supraventricular Tachycardia (PSVT) and a pulse rate over 200 bpm, initial treatment often includes antiarrhythmic drugs like amiodarone or diltiazem. However, when these fail, intravenous adenosine is the treatment of choice. Adenosine works by temporarily blocking the AV node, effectively terminating the arrhythmia and restoring normal sinus rhythm. It is highly effective for PSVT, especially when other medications do not yield results. #AasthaCares #Small

If you experience significant heart palpitations you may have supraventricular tachycardia – or SVT. This condition occurs because of an abnormal heartbeat. SVT palpitations can last for hours or, in some cases, multiple days. Dr. Benjamin Mathew, an interventional cardiologist, explains more about symptoms and treatments for SVT. | Sentara Martha Jefferson Hospital
