Cardiac glycoside that slows and strengthen heart (positive inotropic, negative chronotropic)
Lidocaine class and uses
Class 1b, alternative to amiodarone, 2nd line for VFib &shock resistant Vtach; 1st line for wide QRS
Beta blockers class, activity & use
Class II, Negative inotropic, negative chronotropic vasodilators that slow heart in V-tach/V-fib (sotalol & propranolol)
Drug choices to slow, then restore, atrial flutter
Diltiazem/verapamil or digoxin to slow; amiodarone/flecainide to restore rhythm
AV conduction abnormalities can be caused by these drug groups
Beta blockers, calcium blockers & digitalis all can cause this conduction abnormality
2nd line for PSVT, narrow QRS tachy or non-converting Afib. Rx: Afib, hypertension, angina
Diltiazem & verapamil group & uses
Calcium blockers that slow heart, re-entry SVT & recurrent narrow QRS tachy
Class & name of drugs that lower BP & weaken heart by blocking calcium entry
Calcium blockers (verapamil & diltiazem) action
Verapamil & diltiazem class & uses
Calcium blockers (class 4) used after adenosine in PSVT & narrow QRS tachy
Drugs that activate "fight or flight" to speeds heart & raises BP (Eg)
Epinephrine 1st & 2nd line uses
1st line all pulseless (Vfib, VT, PEA, asystole) & 2nd line Brady after Dopamine
1st line trio for STEMI
Beta blocker (propranolol), clopidogrel (anti-platelet) & heparin (thrombolytic)
1st line quartet for NSTEMI or hi-risk angina
Nitroglycerin, Beta blocker (propranolol), clopidogrel (anti-platelet) & heparin (thrombolytic)
Calcium blockers traits and names
Negative inotropics, negative chronotropic, negative dromotropic, increase repolarization. (Verapamil & diltiazem)
Class 1c action
No change in AP length, slows fast conduction, no change in repolarization. Rx PAfib, PVCs (bigemminy/trigemminy).
Class 3 action & names
Class that blocks K channels, slows & strengthen heart, extends repolarization
Class 3 uses
Class used for 1st line wide QRS, 2nd line pulseless Vfib, VT Rx: serious dysrhythmias, PVCs
Class 4 action, verapamil and diltiazem
Ca channel blockers, decrease AV conductivity & block re-entry rhythms,
Cardiac glycoside action & Rx
Slow Na/K pump, increase Ca, decrease slow (AV) conduction positive inotropic, Rx CHF
Quinidine, flecainide, verapamil interactions
These drugs double digoxin effect, impairs renal activity
