CALCIUM CHANNEL BLOCKERS
Calcium channel blockers are like valium for your heart. Calms the
heart down. Indicators – tachycardia, tacharythmias
Negative intropic, chronotropic, dromotropic (relax your heart, calm it
down)
They treat – A (antihypertensives), AA (antianginal), AAA (anti-atrial
arythmia) they treat atrial dysrhythmias and supraventricular
contractions (SVT)
Names – majority end in -dipine (amlodipine, nifedipine) & verapamil,
m
er as
cardizem (can be given as a continuous IV drip)
Side e/ects – headache & HYPOtension (take BP before administering,
