Be Still, My Heart: The Latest in Arrhythmia Treatment

The smooth, steady rhythm of our hearts beating is something we take for granted. The heart’s electrical system usually functions quietly and effortlessly while we go about the business of our days.

But sometimes, the electrical system is impaired and the rhythm goes awry. This common condition, known as arrhythmia, is usually harmless, but in some people it can be serious or even life-threatening.

If you have arrhythmia, your heart may beat too fast (tachycardia), too slow (bradycardia), or irregularly. The most common form is atrial fibrillation, or A-Fib, which causes rapid, irregular beating or quivering of the heart's upper chambers. Blood may pool and clot inside the heart, increasing the risk for heart attack and stroke.

A less common, but more deadly, type of arrhythmia is ventricular fibrillation, or V-Fib. During V-Fib, the heart’s lower chambers quiver and the heart can't pump any blood, causing cardiac arrest. V-Fib leads to death unless treated right away with an electrical shock to the heart (this is the life-saving procedure you often see on TV, known as defibrillation).

Restoring a Regular Rhythm

“Electrophysiologists treat abnormal heart rhythms in several different ways,” explains Kevin Kravitz, MD, cardiovascular specialist and electrophysiologist with Greenville Heart Care. Some arrhythmias are harmless and require no treatment. But if it looks like arrhythmia is putting your health at risk, there are several options for treatment. Dr. Kravitz discusses treatments for arrhythmias.

How do electrophysiologists treat abnormal heart rhythms?

Electrophysiologists treat abnormal heart rhythms in several different ways. There are fast rhythms of the heart and there are slow rhythms of the heart. Some of those rhythms can be treated with medications; some of those rhythms can be, can be treated with ablation, which is a curable procedure for rhythm problems. Some patients will need pacemakers for slow is rhythms. And some will need defibrillators for fast, dangerous life-threatening rhythms.

 

Treatment options include:

Medication

Beta blockers, or anti-arrhythmics, are medications that can return your heart rate to a normal rhythm. Others, like calcium channel blockers, digoxin (digitalis), and amiodarone can help slow your heart down.

Blood-thinning (anti-coagulant) medication is often used to prevent or treat the blood clots that might form as a result of arrhythmia.

Cardioversion Be Still My Heart - In Content

There are two types of cardioversion, electrical and medicinal.

In electrical cardioversion, you are temporarily put to sleep, and low-energy electrical shocks are given to your heart to trigger a normal rhythm. Electrical cardioversion isn't the same as emergency defibrillation. It's planned in advance and done under carefully controlled conditions. This is usually an outpatient procedure.

If you have arrhythmia, your heart may beat too fast (tachycardia), too slow (bradycardia), or irregularly.

Cardioversion by medicine is usually done in a hospital, but it also can be done at home or in your doctor’s office.

Implants

Two kinds of implants are used to treat arrhythmia.

  • Pacemaker. This is a small device that has wires that are implanted in the heart tissue. The pacemaker works continuously to send electrical impulses that help the heart beat in a regular rhythm.
  • Implantable Cardioverter Defibrillator (ICD). Like a pacemaker, this device has wires that are implanted into the heart tissue. It delivers electrical shocks when it detects a problem with the heart’s rhythm. Some newer versions also serve as a pacemaker.

New Treatment Options

Great advancements are being made in treating heart arrhythmias, according to Mark Krebs, MD, a cardiac electrophysiologist with Miami Valley Cardiologists, Inc. “These interventions are driven largely by different technologies,” Dr. Krebs says, “and engineers continue to come up with new devices and new techniques for treating and helping patients live healthier and full lifestyles.”

Dr. Krebs discusses advanced treatment options for patients with arrhythmias.

What advanced treatment options are available for those with heart rhythm disorders?

Premier Health has invested and a wide range of equipment to treat abnormal heart rhythms. This equipment includes magnetically driven robotics, such as stereotaxis, the ability to burn or freeze abnormal heart rhythms through radiofrequency energy or cryoablation. Every individual’s heart rhythm problem is unique, and treatment is tailored to that individual and their needs through the use of this equipment and different technologies.

 

In cardiac ablation, a thin, flexible tube (catheter) is inserted into an artery in the groin. It is then gently guided through the artery to the heart, where the physician carefully destroys malfunctioning heart tissue using radiofrequency, laser energy, or cryotherapy (freezing) to scar the problematic areas. The scarred areas will no longer send abnormal signals. If successful, the heart will return to a normal rhythm.

One of the newest tools available to electrophysiologists is robotic-assisted magnetic navigation (stereotaxis), which allows them to navigate the catheter remotely and with more accuracy. When the diseased part of the heart is located, tiny electrical pulses are precisely administered to correct the arrhythmia.

Another option is the complex maze procedure. The surgeon creates small cuts in the upper part of the heart and then stitches them together. This causes scar tissue to form, which interferes with the transmission of electrical impulses that can cause A-Fib. This restores the heart to a normal rhythm.

If you have an arrhythmia, rest assured that treatments continue to advance. Working closely with their doctors, most patients can find a way to manage their irregular heart rhythms and lead a healthy and productive life.
