Gene therapy alternative to calcium channel blockers
... As many as 2.2 million Americans are living with atrial fibrillation (one type of rhythm problem.) Arrhythmias can occur in a healthy heart and be of minimal consequence, or they can lead to more serious heart disease, stroke or sudden cardiac death.
