Class IV Antiarrhythmics - Ca Channel Blockers Flashcards
1
Q
Diltiazem (Class, MOA, Indications, CI, AE’s)
A
[Class IV - nonDHP Ca Channel Blockers] - rate control
MOA: blocks Ca channels –> inc. phase 0 threshold –> slows impulse propagation
Indications: Supraventricular arrhythmias (ST, AF, AFL)
CI: Heart failure
AE’s: may NOT stop arrhythmias (like other rate control drugs)
2
