Q

why is Verapamil better than Diltiazem in treating SVTs

A

because verapamil has greater action on the AV node. Dilitazem, on the other hand, has greater action on the SA node

Q

in patients with prinzmetal angina, chest pain relief may be obtained with the ff except: nitroglycerine, verapamil, or diltiazem?

A

lahat pwedeng ibigay!!!!

47
Q

IV nitrogylcerine can be given in patients with acute MI to decrease myocardial oxygen demand… except for what specific kind of MI

A

inferior wall with RV infarct… because RV is dependent on blood volume (Frank starling…) because IV nitroglycerine kasi decreases preload so pag decrease ang preload, konti lang blood pumapasok sa right ventricle… decreased strethc due to frank starling mechanism so decreased cardiac output… Eh nag infarct na nga dun so given na konti na ang contractility nun… so kaya contraindicated
