This prevents the from producing too much of the hormone, which can lead to . ARBs or angiotensin II receptor blockers work ...Calcium channel blockers and beta-blockers are useful for this indication. Digoxin, because of its ability to activate the vagus nerve (parasympathomimetic effect), can also reduce AV conduction velocity to normalize ventricular rate during atrial flutter or fibrillation, particularly in heart failure patients.

Calcium channel blockers act on phase 0 of pacemaker cell action potentials by blocking the influx of calcium ions into the cell. This decreases depolarization rate and amplitude thereby decreasing SA node automaticity, AV conduction velocity, and ultimately heart rate (negative chronotropy).• Calcium channel blockers reduce blood pressure across all patient groups, regardless of sex, race/ethnicity, age, and dietary sodium intake. • Nondihydropyridine calcium channel blockers are more negatively chronotropic and inotropic than the dihydropyridine subclass, which is important for patients with cardiac dysrhythmias or who need ...
