While DIGOXIN (LANOXIN) is the most versatile and widely used cardiac glycoside (anti-arrhythmic) to treat atrial fibrillation and heart flutter, it is no longer the first line drug of choice to treat Congestive Heart Failure (CHF). THE FIRST LINE DRUGS OF CHOICE FOR CHF are BETA BLOCKERS or ACE INHIBITORS.
For dentists and hygienists, it is best practice to treat the CHF patient in the SEMI-SUPINE/SEMI-RECLINING or UPRIGHT POSITION in the dental chair (not in the supine position). Remember: Dental treatment is contraindicated with uncontrolled CHF. Source: DENTIN NBDE II & NBDHE study guides.
