PVC Ablation in Los Angeles

Understanding PVC ablation

What PVCs are

Premature ventricular contractions (PVCs) are extra heartbeats that start early in the lower chambers. The beat after a PVC often feels stronger, which is why many people describe a skip, flip or thud in the chest.

Some people feel PVCs mostly at rest or when lying down at night, when there is less to distract them. Others notice them during or after exercise. When they happen, and how they feel, are worth noting for your physician, because patterns can help guide testing.

PVCs are very common, and many people have them without knowing. In a healthy heart they are often harmless. An electrophysiologist helps you sort out whether yours need treatment or simply an explanation.

When treatment is considered

Treatment usually becomes a question when PVCs cause symptoms that affect daily life, or when they are very frequent. In some people, a large number of PVCs over time can weaken the heart’s pumping. This is called PVC-induced cardiomyopathy, and it may improve when the PVCs are reduced.

First steps often include checking for triggers such as poor sleep, stimulants or thyroid problems, along with an echocardiogram to look at heart structure. Some people also try medicines such as beta blockers. Our guide on caffeine and heart rhythm covers one common question.

Measuring how often PVCs happen

A Holter or patch monitor worn for one or more days counts your PVCs and records their shape. That shape gives clues about where in the heart they start.

Many PVCs come from one small area, often the outflow tracts where blood leaves the heart. When most of your PVCs look the same on the ECG, they likely share one source, which makes a focused ablation more practical.

Living with PVCs while you decide

Feeling extra beats can be stressful, and stress can make you notice them more. Knowing that your heart structure is normal often brings real relief. Our guide on heart rhythm and anxiety explains this link.

Steady sleep, regular exercise that your physician approves and limits on stimulants help some people feel fewer PVCs. These steps will not suit everyone, but they cost little to try. Keep a short diary of when your extra beats are worse, since patterns can point to triggers.

If you are thinking about ablation, write down your questions before your visit. Ask what your monitor showed, where your PVCs likely start and what would happen if you chose to wait.

What happens during the procedure

Thin catheters are guided into the heart through a vein, and sometimes an artery, at the top of the leg. Your electrophysiologist maps the heart to find the spot that fires earliest during each PVC, then applies energy there.

Because the map depends on catching PVCs as they happen, your care team may ask you to pause certain rhythm medicines beforehand. Only do this on your physician’s instructions. Lighter sedation is often used, since deep sedation can quiet the PVCs during the procedure.

Recovery and follow-up

You can often leave the same day or after one night. Expect some tiredness and bruising where the catheters went in. Your physician will advise when you can drive, lift and exercise.

A repeat monitor is usually arranged a few weeks or months later to see how much your PVCs have decreased. If PVCs had weakened your heart, a follow-up echocardiogram can show whether its pumping has recovered.

Risks

PVC ablation is a well-established procedure. Bruising or bleeding at the catheter site is the most common issue. Rarer risks depend on where the PVCs start and include injury to the heart, nearby blood vessels or the heart’s normal wiring. Your physician explains how your PVC location affects your own risks.
