CALCIUM CHANNEL BLOCKERS
• Calcium channel blockers are like valium for your heart. Calms theheart
down. Indicators – tachycardia, tacharythmias
• Negative intropic, chronotropic, dromotropic (relax your heart, calm itdown)
• They treat – A (antihypertensives), AA (antianginal), AAA (anti-atrial
arythmia) they treat atrial dysrhythmias and supraventricularcontractions
(SVT)
• Names – majority end in -dipine (amlodipine, nifedipine) & verapamil,
cardizem (can be given as a continuous IV drip)
• Side effects – headache & HYPOtension (take BP before administering,hold if
systolic is <100)

CARDIAC ARRYTHMIAS
• QRS refers to – Ventricular
• P refers to – Atrial
