19
Q

Factori de risc mcs

A

Ic! Cu fe<30
Imfarct miocardic cronic! Adica cu cicatrice
Pacientul care a avut tahi ventr sau oprire cardiaca

20
Q

Sunt extrasistolele ventr factor de risc pt mcs?

A

Nu
Doar daca s asociate cu ic
Deci pe scurt mai imp e fct cardiaca

21
Q

Sa ekg

A

Potentiale tardive
Signal average ekg
Pot terminala a qrs si se vede daca exista oscilatii ale potentialului cardiac
Putere predictiva negativa

22
Q

Deci daca pacientul are potentiale tardive sau variabilitate voltaj

A

Nu ins ca o sa moara

Daca daca nu are inseamna ca nu o sa moara

23
Q

Pierdere k, scsdere v decrepolarizare si prelungire pa
Gain na, prelungire dep si prelungire pa
Pa=qt=>

Qt lung e prim loss k, gain na
Inomogenitate electrica

34

Q

Brugada

A

Morti subite endemice in asia de s e(non lai thai) in somn!
Mai ales in decada 4
In repaus, somnx, mai des la barbati, au atitmii supeaventr frecvente

Scn5a!(din alfa)

Defibrilator implantabil

37
Q

Ce se int in brugada

A

Intre endocard si epicard e o diferenta de ito(mai mare in epicard)=>repolarizare mai rap a epicardului decat a endocardului (Dar e imperceptibil cand nu exista brugada)
Cand adaug si modificarea pe canalul de sodiu=> diferenta e f mare
Gradient de voltaj intre endocard si epicard=>
Reintrare de faza a 2 a
