If you don’t find the term you are looking for—email us and we’ll add it to the Glossary.

Beta Blocker: A medication that slows down conduction through the heart and makes the AV Node less sensitive to A-Fib impulses.

Calcium Channel Blocker: A medication that prevents or slows the flow of calcium ions into smooth muscle cells such as the heart. This impedes muscle cell contraction, thereby allowing blood vessels to expand and carry more blood and oxygen to tissues.

NOAC: NOAC stands for Novel Oral AntiCoagulants. NOACs are alternatives for vitamin K antagonists (e.g., Warfarin) for stroke prevention in patients with atrial fibrillation.

“Pill-in-the-Pocket” Treatment: For Paroxysmal A-Fib patients. When an A-Fib attack occurs, the patient takes an antiarrhythmic med (flecainide, propafenone, etc.) to return to normal sinus rhythm.

Rate Control Medications: Drug therapy that attempts to control your heart rate (ventricular beats), but leave the upper chambers (atria) of your heart in A-Fib.

Rhythm Control Medications: Drug therapy that uses rhythm control drugs, called antiarrhythmics, to try to stop A-Fib and make the heart beat normally.
