Apare la cel cu boli pulm severe
Asta e imp ptc multifocala da in fia

Q

Tahi prin reintrare nodala

A

O varianta anormala a circ intranodala=cale dubla
Mecanism: impulsul vine, gaseste calea rapid blocata si o ia pe calea beta. Calea alfa iese intre timp din p refr deci impulsul se intoarce pe calea rapida(pe calea gresita)

21
Q

Multifocala

A

Mai multe centre care capata automatism
E imp ca e neregulata
E premergatoare fia
Deci daca vad ca bpco isul meu are fia il monitorizez des

Reintrare nodala
Fascicul accesor
Flutter
