The Role of Ablation: How Catheter Ablation Can Treat Persistent Tachycardia

Persistent tachycardia occurs when the heart beats too fast for extended periods or when a rapid heartbeat keeps coming back. In general, tachycardia refers to a resting heart rate above 100 beats per minute.

It’s expected for your heart rate to temporarily increase during stress or exercise. Persistent tachycardia may persist even at rest.

People with persistent tachycardia often experience symptoms. Common symptoms include:

• Heart palpitations
• Dizziness
• Fatigue
• Chest discomfort
• Shortness of breath
  
  

In some cases, the condition can interfere with daily life. It may even increase the risk of other heart complications.

Fortunately, several tachycardia treatment options are available. One of the most effective solutions is catheter ablation for tachycardia. This treatment is minimally invasive. It targets the source of abnormal electrical signals in the heart and can help restore a normal rhythm.

At Cardiovascular Center of Florida, patients benefit from advanced electrophysiology procedures. These procedures are performed by experienced heart rhythm specialists. They focus on diagnosing and treating complex arrhythmias.

What Is Persistent Tachycardia?

Tachycardia is a heart rate that exceeds 100 beats per minute at rest. While temporary increases in heart rate can be normal, persistent tachycardia occurs when the abnormal rhythm continues for long periods or happens repeatedly.

Persistent tachycardia treatment is based on identifying the underlying cause and the specific type of arrhythmia involved. Some forms of tachycardia respond well to medications. Other forms of tachycardia may require more advanced treatment.

Several types of tachycardia can often be treated using catheter ablation, including:

• Supraventricular tachycardia (SVT)
• Atrial tachycardia
• Certain forms of ventricular tachycardia
  
  

When episodes become frequent or medications fail to control symptoms, doctors may recommend an electrophysiology procedure to correct the abnormal electrical pathway in the heart.

What Is Catheter Ablation?

A cardiac ablation procedure is a minimally invasive electrophysiology procedure. It is used to treat abnormally fast heart rhythms. The goal is to locate the small areas of heart tissue responsible for generating irregular electrical signals. Once located, those areas can be eliminated.

During catheter ablation, thin flexible tubes called catheters are inserted through a vein, typically in the groin. These catheters are carefully guided to the heart using advanced imaging and mapping technology, identifying faulty electrical pathways within the heart.

Abnormal pathways allow electrical signals to circulate repeatedly, triggering rapid heart rhythms.

The heart rhythm specialist will identify the abnormal electrical pathway and deliver energy through the catheter to destroy or isolate the tiny area of tissue causing the problem. This energy may be delivered using radiofrequency heat or cryoablation, which freezes the tissue. Once the pathway is eliminated, the heart can return to its normal rhythm.

Most cardiac ablation procedures take two to four hours, depending on the complexity of the arrhythmia. Patients are typically given sedation or light anesthesia to ensure comfort during the procedure.

Ablation for SVT and other tachycardia conditions often provides long-term relief and may reduce or eliminate the need for ongoing medication. Both radiofrequency and cryoablation are equally successful long term.

Is Catheter Ablation Safe?

Many patients ask, “Is catheter ablation safe?” For most individuals, the procedure has a strong safety profile when performed by experienced electrophysiologists.

Catheter ablation is considered minimally invasive. It typically involves a shorter recovery time than open-heart procedures. Success rates are particularly high for ablation for SVT and other common rhythm disorders.

As with any medical procedure, there are some risks. Possible complications may include:

• Bleeding at the catheter insertion site
• Infection
• Damage to nearby structures
  
  

Serious complications are uncommon but can occur in rare cases. Choosing an experienced heart rhythm specialist is an important factor in reducing risks and improving outcomes.

When to See a Heart Rhythm Specialist

If you experience ongoing symptoms of tachycardia, it may be time to consult a heart rhythm specialist in Orlando.

Patients should seek evaluation if:

• Medications are not controlling symptoms
• Tachycardia episodes occur frequently
• Symptoms include fainting, severe dizziness, or chest discomfort
• Heart rhythm issues are affecting daily activities or quality of life
  
  

An electrophysiology evaluation can help determine whether catheter ablation or another treatment option is best for you.
