What does the P wave look like in a junctional ryhthm?
|
P wave always is inverted & most often hidden in the QRS complex.
|
|
|
What is the reason for the unusual configuration of the P wave in junctional rhythms?
|
The atria are depolarized via retrograd conduction and the electrical flow is traveling away from the electrode in Lead 2,causing wave form to
|
|
|
Will the QRS complex be normal in a junctional rhythm?
|
Ventricular depolarization will be normal and measurement will be less then .12.
|
|
|
Does an iverted P wave always indicat a junctional
|
No, atrial rhythms can also have inverted P waves. In a junctional rhythm the PRI will be less than .12 sec.
|
|
|
What is the biggest clue to a junctional rhythm?
|
The inverted P wave.
|
|
|
What is Premature Junctional Contraction (PJC)?
|
A PJC is a single beat that originates from an irratable focus in the AV junction.
