Calcium Channel Blockers -CCBs are like "valium" for your heart --Valium calms you down. Therefore, CCB relaxes and slows down the heart ---If the heart is tachycardic, tachyarrhythmia, or heart attack → needs to be rested → GIVE CCB ---If you are in shock, or you are in heart block → needs to be stimulated → should NOT give CCB inotropic, chronotropic and dromotropic effects of CCBs -In other words, CCBs have negative inotropic, chronotropic, and dromotropic effects on the heart -Posit...
