Common Treatments

The underlying cause of any heart rhythm disorder provides the basis for selecting the best treatment plan. In general, the best treatment is the least invasive option that effectively controls the heart rhythm disorder.

Treatment options fall into several categories from the least to the most invasive and include the following:

Lifestyle Changes – Since other heart disorders increase the risk of developing abnormal heart rhythms, lifestyle changes often are recommended. Living a “heart healthy” lifestyle can ease the symptoms experienced with heart rhythm disorders and other heart disorders, and can be beneficial to overall patient health.

Medications – Many abnormal heart rhythms can be controlled with medications or treat related conditions such as high blood pressure, coronary artery disease, heart failure, and heart attack. Medications are also used to reduce the risk of blood clots in patients with certain types of abnormal heart rhythms.

Electronic Devices – By delivering a controlled electric shock to the heart, defibrillators or cardioverters “shock” the heart back into a normal heart rhythm. Sometimes the devices are external, such as in an emergency situation. Often, the electronics are implanted in the patient’s chest.

Implanted cardioverter defibrillators (ICDs) – ICDs continuously monitor the heart rhythm, automatically function as pacemakers for heart rates that are too slow, and deliver life-saving shocks if a dangerously fast heart rhythm is detected. These devices are 99 percent effective in stopping life-threatening abnormal heart rhythms and are the most successful option to treat ventricular fibrillation (VF), the major cause of sudden cardiac arrest(SCA).

Pacemakers – Devices that “pace” the heart rate when it is too slow (bradycardia) can take over for the heart’s natural pacemaker, the sinoatrial node, when it is not working properly. Pacemakers monitor and regulate the rhythm of the heart and send electrical signals to stimulate the heart if it is beating too slowly.

Devices for Heart Failure – A cardiac resynchronization therapy (CRT) device is a special type of pacemaker for certain patients with heart failure. The implanted device paces both the left and right ventricles (lower chambers) of the heart at the same time. This helps to resynchronize muscle contractions and improve the efficiency of the weakened heart.

Therapeutic Procedures        

Cardioversion – During this brief procedure, an electrical shock is delivered to the heart to convert an abnormal heart rhythm back to a normal rhythm.

Catheter Ablation – During this procedure, one or more flexible, thin tubes (catheters) are guided into the blood vessels and to the heart muscle. A burst of energy heats and destroys very small areas of tissue that cause the abnormal electrical signals.

Surgery - Although surgery is sometimes used to treat abnormal heart rhythms, it is more commonly used to treat other heart problems, such as coronary artery disease and heart failure. Correcting these conditions may reduce the risk of abnormal heart rhythms.

 

 

The first step in treating any abnormal heart rhythm to determine the underlying cause of the problem. With that information, patients and their families, together with their doctors, can discuss all of the options while considering the circumstances of each individual case. The following are some things to consider when selecting the most appropriate treatment option:

  • What is the nature and severity of the heart rhythm disorder and its symptoms?
  • Are there underlying conditions that contribute to the heart rhythm disorder or impact the patient’s health or quality of life?
  • How does age, overall health, and personal and family medical history factor into the treatment decision?
  • What, if any, medications are being taken to treat any other medical conditions?
  • Are there concerns about end-of-life issues?

By talking openly to your doctor, you will know what treatments are best for you. Your doctor can provide advice based upon your concerns, value and priorities; a process called shared decision-making. Even if you simply want to follow your doctor’s recommendations, answers to these questions will help you understand your choices.

Early Warning Signs
Over 2.5 million people experience a racing, pounding, rumbling or flopping feeling in their chest but don't know that it could be Atrial Fibrillation which increase the chance of stroke by 500%. Maybe you are seeing irregular heart rhythm readings on your new wearable health device and are not sure what it means. If you been fainting or having repeated dizzy spells, it's time to see a doctor to discuss your heart health.
Heart Rhythm Disorders
Millions of people experience irregular or abnormal heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart disease. However, some abnormal heart rhythms can be serious or even deadly. Having other types of heart disease can also increase the risk of arrhythmias.
The Normal Heart
The heart is a fist-sized muscle that pumps blood through the body 24 hours a day, 365 days a year, without rest. The normal heart is made up of four parts: two atria on the top of the heart (right atrium and left atrium), and two ventricles (right ventricle and left ventricle) which are the muscular chambers on the bottom of the heart that provide the major power to pump blood.
Lifestyle
Since other heart disorders increase the risk of developing abnormal heart rhythms, lifestyle changes often are recommended. Living a “heart healthy” lifestyle can ease the symptoms experienced with heart rhythm disorders and other heart disorders, and can be beneficial to overall patient health.
