2024年2月2日 · Ventricular tachycardia ablation, also called VT ablation, uses cold or heat energy to create tiny scars in the heart. The scars block faulty signals that cause a rapid, erratic heartbeat. VT ablation is a treatment for a type of irregular …

VT ablation targets the regions of VT circuit such as slow conduction zones called the isthmus. 3-dimensional mapping systems permit identification of the critical parts of the circuit without inducing VT, a technique called substrate mapping.

2007年5月29日 · Electrophysiological study with catheter ablation is often warranted to confirm the diagnosis, to provide further evidence for the absence of ventricular scar or other disease, and often to cure the arrhythmia. Ablation is also an option for symptomatic nonsustained VT and frequent ventricular ectopy in these patients. 1.

2024年11月7日 · Cardiac ablation (catheter ablation) is a minimally invasive procedure that creates scars to stop the electrical impulses that cause irregular heart rhythms. Healthcare providers can use cardiac ablation to manage abnormal heart rhythms that don’t respond to …

Catheter ablation of ventricular tachycardia (VT) is a percutaneous therapy that can effectively eliminate VT and prevent VT recurrence. Unlike ICDs, however, there is more limited evidence showing overall survival improvement after VT ablation.

The ablation of ventricular tachycardia is an intervention that consists of the selective destruction (ablation) of the cardiac tissue where the circuits responsible for initiating and maintaining these arrhythmias are found.

2010年7月20日 · Radiofrequency ablation is delivered (Abl:ON) at a site determined by mapping. The VT stops after 2 seconds of burning, and normal heart rhythm is restored. There are 3 treatment options for VT, although many patients require a combination: an ICD, antiarrhythmic medications, or catheter ablation.

2011年5月24日 · There are 3 treatment options for VT, although many patients require a combination: an implantable cardioverter-defibrillator (ICD), antiarrhythmic medications, and catheter ablation. An ICD provides abortive “rescue” …

Ventricular tachycardia (VT) ablation is a treatment that can help restore normal heart rhythm to patients experiencing an erratic heartbeat. Learn more here.

2024年12月10日 · VT ablation can take anywhere from 2 to 6 hours. The procedure takes place in a room similar to an operating theatre, called a cath lab. The procedure involves: using the tip of the catheter to ablate (burning) abnormal connections in the heart causing the VT. This is performed using x-ray guidance.
