Ventricular Tachycardia Ablation (VT Ablation)

Specialist treatment of ventricular tachycardia, including complex scar-related substrates.

Three-dimensional mapping of ventricular tachycardia
Understanding the service

What is it and what is its purpose?

VT may arise from a localised focus or electrical circuits around scar tissue. Ablation uses advanced mapping to identify the critical sites that initiate or sustain the arrhythmia.

The aim is to reduce VT recurrences and, in patients with an ICD, appropriate therapies or shocks. The strategy depends substantially on underlying heart disease, scar extent and the location of the arrhythmogenic substrate.

How it is performed

  1. 01

    Detailed assessment with ECG, imaging and evaluation of underlying heart disease.

  2. 02

    Endocardial mapping and, in selected cases, epicardial access.

  3. 03

    Targeted ablation and a structured follow-up plan.

The patient experience

What to expect, step by step

Understanding the procedure helps you arrive better prepared and with greater confidence.

Three-dimensional mapping of ventricular tachycardia
Mapping identifies early activation sites or scar regions involved in the ventricular arrhythmia.
01

On the day of your investigation or treatment

Catheters and three-dimensional mapping identify the focus or scar substrate. Depending on complexity, deep sedation or general anaesthesia may be required, with access to the outer surface of the heart in selected cases. Circulation and rhythm are continuously monitored.

BEFORE

Preparation

Preparation depends on heart function, the presence of an ICD, anticoagulation and the type of arrhythmia.

AFTER

The first few hours

Monitoring is closer than after a simple diagnostic study and hospital admission may be required. Access sites, the ECG and any implanted device are checked.

RETURN

Back to everyday life

Recovery is tailored to the extent of treatment and heart function. There is no single timetable for returning to work and exercise; activity progresses after review, with clear instructions on symptoms requiring immediate contact.

Important

This is a specialist treatment requiring an individual assessment of benefits and risks. Your treating team's individual instructions always take priority over the general information on this page.

Frequently asked questions

Practical answers before your appointment

Will it hurt?

The puncture or incision site is numbed. You may feel a brief sting, pressure or palpitations during mapping. Sedation and pain relief are tailored to the procedure and your needs.

Should I stop my medication?

Not without specific medical instructions. Anticoagulants, antiarrhythmics, diabetes medicines and other treatments may require special management, tailored to each patient and procedure.

When will I know the result?

The main findings and immediate outcome are usually explained before discharge. Final assessment includes your recovery and scheduled follow-up.

When is urgent help needed?

Severe or worsening chest pain, severe breathlessness, fainting, bleeding that does not stop or rapidly increasing swelling at the access site need immediate assessment. Follow your discharge instructions or call 112.
