Mechanistically, these drugs cause vasodilation, and dilate the arteries more than the veins. Clinically, they can be used to treat chest pain. They also treat hypertension by lowering blood pressure. Side effects include hypotension, reflex tachycardia, edema, facial …Slow calcium channel blockers and beta-blockers are medications that affect AV nodal function. The PR interval on the EKG defines the time needed for an impulse to travel through the atrium and AV nodal system to the ventricles. AV node conduction is the slowest, and PR interval variations reflect changes in AV nodal activation time.Uses of calcium channel blockers Traditional Initially, calcium channel blockers were introduced for the treatment of angina, arrhythmias and hyper- tension.
