d) Wenckeback Which of the following is the
This is a 5:4 block (5 P's 4 EKG abnormality in this patient?
QRS) a) normal EKG
This is considered benign b) left anterior fascicular block
and the AV conduction is c) 1st degree AV block
occasionally d) Wenckeback
(incompletely) blocked. e) Mobitz type 2
The PR interval f) complete heart block
progressively lengthens
until the QRS is dropped.
Parasympathetic
stimulation makes this
WORSE (for example, you
would see a 4:3 block go
to a 5:4 block), this would
make it better for a Mobitz
type 2.
Mobitz type 2 is classified
by how many PR intervals
to how many QRS there
are.
Fascicular blocks are in
the left bundle and are
supplied by different
vessels. Left anterior is
supplied by the left
coronary artery
(commonly seen with
RBBB because they share
a blood supply). Left
posterior is supplied by
the right coronary artery.
LAFB would show a +QRS
in lead I, and - in II and III
LPFB would show a -QRS
in lead I, and + in II and III
