Catheter ablation of most arrhythmias has a high success rate. Success rates for WPW syndrome have been as high as 95% [2] For Supraventricular tachycardia (SVT), single procedure success is 91% to 96% (95% Confidence Interval) and multiple procedure success is 92% to 97% (95% Confidence Interval). [3]
Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia , which start within the lower chambers of the heart . [ 2 ]
ablation equipment to destroy abnormal tissue; an electroanatomic mapping system that tracks and records the catheter position in 3D and associated electrical signals; ready access to cardiac medications such as adenosine, atropine, dopamine, and isoproterenol; ready access to an assortment of introducer sheaths and catheters
The catheter removes heat from the tissue to cool it to temperatures as low as -75 °C. This causes localized scarring, which cuts undesired conduction paths. This is a much newer treatment for supraventricular tachycardia (SVT) involving the atrioventricular (AV) node directly. SVT involving the AV node is often a contraindication for using ...

Future episodes can be prevented by catheter ablation. [3] About 2.3 per 1000 people have paroxysmal supraventricular tachycardia. [5] Problems typically begin in those 12 to 45 years old. [3] [5] Women are more often affected than men. [3] Outcomes are generally good in those who otherwise have a normal heart. [3]
Ablation therapy is a catheter based ablation of lesions in the heart (with radiofrequency energy, cryotherapy (destructive freezing), microwave, or ultrasound energy) to cure or control arrhythmias (see radiofrequency ablation). Ablation is usually performed during the same procedure as the electrophysiology study during which arrhythmias are ...

Highlighted in yellow is the P wave that falls after the QRS complex. Specialty: Cardiology: Symptoms: Palpitations, chest tightness, neck pulsation: Diagnostic method
