Electrophysiologists Treat Heart Rhythm Disorders

Cardiologists who specialize in electrophysiology diagnosis and treat disorders associated with the heart's electrical systems are called electrophysiologists. These disorders include atrial fibrillation, bradycardia (slow heart rhythm) and tachycardia (fast heart rhythm).

Atrial Fibrillation

Atrial fibrillation is a common heart rhythm problem, particularly in people over the age of 70. In some cases, medications may be sufficient to control symptoms. If medications are insufficient, an ablation may be recommended.

Reducing Atrial Fibrillation's Fear Factor

It’s a common scenario in a cardiology clinic when the cardiologist informs the patient they have atrial fibrillation (AFib), an abnormal heart rhythm characterized by rapid and irregular beating. Shock and fear take over, especially once the cardiologist says something about “increased risk of stroke.” Mathew Hutchinson, MD, discusses how AFib and stroke risks. Read more.

Heart Rhythm Problems

Sometimes an irregular heart beat can be improved by adjusting medications. This may be the situation when the slow heart beat is due to problems with the sinus node (“sick sinus syndrome”). However, often the slow heart beat cannot be improved by medication adjustments, and then a pacemaker is needed. Pacemakers are also needed when there is electrical block of the signals, particularly in “complete heart block”

Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D)

Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D) is an inherited condition that causes abnormal heart rhythms. ARVC/D may account for up to 20 percent of cases of sudden death among young people.
