Both panels are from the same patient with and without pacing.
Compare the LA traces between the two panels.
What is the dominant wave in LA trace in this patient?
Correlate with EKG trace noted above.
(5 yr old, s/p Fontan...1 week postop after surgery to re-route hepatic vein to Fontan circuit secondary to pulmonary AVM)
Comment on the CVP trace. Why aren't there any waves?
