24
Q

ce clase de AA sunt folosite pt aritmii prin mecanism reintrare/ focar ectopic

25
AA care au risc de torsada varfurilor
procainamida ,encainida, flecainida, IIIc,
26
Amiodarona
blocant IIIc, blocheaza can K si can Na
27
cum functioneaza aa de tip IIIc
blocheaza can de K
28
cum blocheaza amiodarona can de Na
e liposolub si se insera in vecinatatea canalului
29
efecte suplimentare amiodarona
antiaritmic ,antianginos, bradicardizant
30
r adverse amiodarona
se poate depozita in tesuturi; miocard pulmonar, cornee,tegumente, tiroida
31
Dronaderona
specific Kr si Ks
32
Dofetilida si Ibutilida
specific Kr, risc tors varfuri , pentru fibrilatie(ibutilida si flutter)
33
Sotalol
beta blocant care blocheaza si can K
34
Bretiliul
doar urgente pt FiV, agraveaza aritmii ventric, tahicardie, inotrop pozitiv
35
Utilizari sotalol
mentinere ritm sinusal dupa FiA , aritmii ventric amenintatoare de moarte
36
actiuni blocante can de Calciu pe cord
scade: excitab, conductib, contractilitate si vasodilatatie
37
actiuni pe fibr miocardica de lucru
scade conductib
38
actiuni pe fb cu automatism
sacde excitab conductib creste PRE
39
Indicatii blocante can de Ca
tahiaritmii supraventriculare
40
putem combina bloc can de Ca cu beta b locante
nu, au aceleasi efecte
41
Utilizari verapramil
FiA, FlA, aritmii prin focar ectopic atriale
42
farmacocinetica verapramil
admin oral sau i.v. in urgente, 70%metab hepatica, restul eliminare renala
43
reactii adverse verapramil
digestive:constipatie si dureri epigastrice SNC:cefalee cardiace;agravare BAV, bradicardie excesiva, decompensare IC, hTA
44
Contraindicatii Verapramil
asociere cu betablocante, bradicardie, hTA
45
Diltiazem-diferente fata de verapramil
deprimare cord mai putin intensa vasodilatatie mai intensa
46
Utilizari digitalice ca AA
FlA, FiA pt saderea frecventei ventriculare, CU MENTINEREA ARITMIEI
47
Utilizare Adenozina
aritmii prin mecanism de reintrare
48
mecanism de actiune Adenozina
actioneaza pe RCPG-stimuleaza deschiderea unor canale de K- hiperpolarizare Scade: excitab , conductibilit si panta DLD
49
R adverse Adenozina
oprirea cordului si reluarea dupa 6 secunde dispnee durere retrosternala bronhospasm
50
Medicament ce potenteaza Adenozina
DIPIRIDAMOL
51
Medicament ce ANTAGONIZEAZA ADENOZINA PRIN BLOCAREA rec adenozinici
teofilina si Cafeina
52
Farmacocinetica Adenozina
DOAR i.v. in bolus
53
Utilizari Ach ca AA
Mecanism de reintrare focar ectopic
54
Utilizari Edrofoniu
Cand manevrele vagale au fost ineficiente
