![]() ![]() There is a 5-10% chance of Ventricular Ectopics or VT recurring after an apparently successful procedure. This procedure carries an approximately 90% chance of curing your Ventricular Ectopics or VT. What is the success rate for ablation of Ventricular Ectopics or Idiopathic VT? If the source is near to your aorta, a coronary angiogram will be performed before ablation to ensure the coronary arteries are not in close proximity or at risk of damage. When the source of ectopics or VT is identified, radiofrequency ablation will be applied to this spot. You may be given some intravenous medications to stimulate the ectopics or VT. The 3-dimensional mapping also helps to localise the source of ectopics or VT. This will help navigate the catheter inside your heart and minimise the need for X-rays. Most Electrophysiologist routinely use a 3-dimensional navigational system which works like GPS navigation to guide the ablation procedure. Catheters will be placed in your heart to identify and localise the abnormal tissue. Please refer to the section on EPS on how EPS is performed. How is Radiofrequency Ablation performed for Ventricular Ectopics or Idiopathic VT? General anaesthesia is not commonly used as it suppresses the ectopics preventing your Electrophysiologist from finding the source of your ectopics. This procedure is usually performed under conscious sedation and local anaesthetic. How do I prepare for Ventricular Ectopic or Idiopathic VT ablation? The next sections will explain this procedure in detail. This is a procedure performed by an Electrophysiologist and is very effective to cure Ventricular Ectopics or VT in normal hearts. All medications come with side effects and your doctor will discuss these with you. ![]() ![]() The aim of medications is to reduce the frequency and severity of your symptoms. Medications suppress the ectopics but do not cure this condition. Tablet treatments can be effective in around 25-50% patients. If your ectopics are occurring very infrequently, you may simply chose to live with it. What are the treatment options for Ventricular Ectopics or Idiopathic VT? Some patients may also be investigated with an exercise treadmill test to quantify the burden of ectopics on exercise. Ventricular Ectopics may be seen on an electrocardiogram (ECG) but in patients with infrequent symptoms, a 24 hour Holter monitor may be undertaken to clarify the pattern and frequency of the ectopic beats. Ventricular Tachycardia from Khan Academy. The commonest location for the source of Ventricular Ectopics or Idiopathic VT in the heart is the Right Ventricular Outflow Tract (RVOT). This is called Idiopathic Ventricular Tachycardia, also described as Focal Ventricular Tachycardia (see video below), which accounts for about 10% of all VTs. VT commonly happens in patients with weakened hearts (heart failure) but as with Ventricular Ectopics, VT can also occur in people with normal hearts. VT can impair the ability of the heart to supply blood and may result in palpitations, dizziness and blackouts. The controlled contraction of the ventricles is important for the heart to pump blood around your body and brain and to maintain a good blood pressure. Some patients feel palpitations which can be unpleasant but will not damage your heart unless extremely frequent.Ī sequence of these ectopics can result in what is called ventricular tachycardia (VT). Most people who have ectopics are completely unaware of them. However, they can be troublesome due to the sensation they sometimes produce. In some people, these can occur while exercising but in others they can occur while sleeping or when relaxing.Įctopic beats are very common and in most people with no other heart disease, they are harmless. Ventricular Ectopics occur when a cluster of cells within the lower chambers of your heart (ventricle) gives rise to the electrical impulse instead of the natural pacemaker of your heart (the sinus node).
