Premature Junctional Complex
|
|
There
could be a NSR with a few early beats from the junctional area.
a. The early beats would have a P wave that is inverted and short,
hidden,
or after the QRS.
b. The
rhythm
would be irregular because of the early beat.
c. All other configurations would be normal.

Junctional Escape Rhythms
|
|
There
could be a NSR with a few late beats from the junctional area.
a. The late beats would have a P wave that is inverted and short,
hidden
or after the QRS.
b. The
rhythm
would be irregular because of the early beat.
c. All other configurations would be normal.

Junctional Rhythm
|
|
The
AV Junction could take over as a secondary pacemaker
a. The
rate would be < 60 because that is the intrinsic rate of the
AV
Junctions
b. The P wave is inverted, hidden
or behind the QRS.
c. The rhythm would be regular
d. If visible the PR would be <
.12 and the QRS and T wave would be
normal
.

|
Accelerated Junctional Rhythm
|
|
There
could be a NSR but because of enhanced automaticity there could
be
3 or more early beats from the junctional area.
a. The early beats would have a P wave that is inverted and short,
hidden,
or after the QRS.
b. The
rhythm
would be irregular because of the early beats.
c. All other configurations would be normal.

|
Junctional Tachycardia
|
|
The
AV Junction could take over as a secondary pacemaker but
the rate is fast.
a. The
rate would be > 100
b. The P wave is inverted, hidden
or behind the QRS.
c. The rhythm would be regular
d. If visible the PR would be <
.12 and the QRS and T wave would be
normal
