Heart arrhythmia treatment in Aurora, Colorado

Heart arrhythmias happen when the electrical impulses that coordinate your heartbeats do not work properly, causing your heart to be too fast, too slow or irregularly. Heart arrhythmia treatment is usually able to control or eliminate these irregularities. Often, heart arrhythmias are made worse—or are even caused—by a weak or damaged heart

Atrial fibrillation

Atrial fibrillation (AFib) is an abnormal and, often, fast beating of the upper part of the heart. The main job of this part of the heart is to push blood into the lower section. The heart then pushes blood out to the body.

AFib can decrease the amount of blood that reaches the lower section of the heart. Less blood in the heart means there will be less blood pumped out to the body. Blood can also become trapped and pool in the upper heart. This increases the risks of blood clots and stroke.

AFib is the most common type of arrhythmia. It affects two million Americans, most of whom are elderly.

Symptoms of AFib

Individuals with AFib may not feel any symptoms. Others may experience:

  • Confusion
  • Confusion
  • Fatigue
  • Difficulty exercising
  • Palpitations
  • Shortness of breath
  • Pain in the chest
  • Weakness
  • Dizziness or fainting


Every year, the cardiac electrophysiologists at TMCA perform multiple procedures to diagnose and treat rhythm disorders of the heart. Our state-of-the-art cath lab is equipped with the latest technology and three fellows of the Heart Rhythm Society, the most prestigious destination for electrophysiologists worldwide.

We conduct electrophysiology studies to determine the source of cardiac rhythm problems. It allows the doctor to accurately diagnose and appropriately treat a patient’s heart rhythm.

Catheter ablation for heart arrhythmias

Catheter ablation is used to treat cardiac arrhythmias. This procedure removes or closes a faulty electrical pathway from sections of the heart prone to developing an arrhythmia. Our skilled cardiologists have been performing catheter ablation for over 25 years for conditions like AFib, ventricular tachycardia and atrioventricular nodal reentrant tachycardia (AVNRT).

Both medication and catheter ablation have been used to treat AFib for over 15 years. However, research indicates that medication may make a heart rhythm worse. We are a research partner in AFib ablation with the Mayo Clinic, continuing our studies on the best treatment options for our patients. We are also a regional leader in the treatment of AFib, with the largest AFib ablation center in Denver.

Catheter ablation can also be used to treat:

Ventricular tachycardia occurs in patients whose heart beats more than 100 beats a minute, with at least three irregular heartbeats in a row. Ventricular tachycardia can develop as a result of a heart attack, heart disease, cardiomyopathy, heart failure, heart surgery and myocarditis. It is sometimes seen in people with healthy hearts, but can still cause severe symptoms.

Wolf Parkinson White or an accessory pathway is characterized by extra pathways, which connect to the atrium and ventricles. In this case, the heart beats faster because the extra pathways cause signals to travel back to the atrium. Patients with this condition can experience dizziness, fainting or, rarely, a life-threatening, rapid heartbeat.

AVRNT is marked by impulses which move in a circle. The impulses re-enter areas that have already been passed through, due to an extra pathway that lies in or near the atrioventricular node.

Is catheter ablation right for me?

Your doctor will perform a thorough evaluation to determine if catheter ablation is the right form of treatment for you.

Your doctor may take into consideration:

  • Your medical history
  • A physical examination
  • Electrocardiogram
  • Holter monitor test
  • Any additional tests or evaluations
