Atrial Flutter PRI | 1) Not measurable |
Atrial Fibrillation PRI | 2) Not measurable |
WPW (WOLF_PARKINSON_WHITE) PRI | If p-waves are seen less than 0.12 sec |
PJC'S PRI | 1) If a P-Wave occurs before the
QRS the PRI will usually be
0.12 sec or less,if no p-wave
occurs before the QRS, there
will be no PRI |
Junctional Escape Beat PRI | 2) If a P-Wave occurs before the
QRS the PRI will usually be
0.12 sec or less,if no p-wave
occurs before the QRS, there
will be no PRI |

QRS the PRI will usually be
0.12 sec or less,if no p-wave
occurs before the QRS, there
will be no PRI |

QRS the PRI will usually be
0.12 sec or less,if no p-wave
occurs before the QRS, there
will be no PRI |
Junctional Tachycardia | 5) If a P-Wave occurs before the
QRS the PRI will usually be

PVC's PRI | 1) None |
Ventricular Escape Beat PRI | 2) None |
Idioventricular Rhythm PRI | 3) None |
Accelerated Idioventricular Rhythm PRI | 4) None |
Monomorphic Ventricular Tachycardia PRI | 5) None |
Polymorphic Ventricular Tachycardia PRI | 6) None |
Ventricular Fibrilation PRI | 7) None |

First Degree Block PRI | Greater than 0.20 sec and constant |
Second Degree Block Type I PRI | Lengthens with each cycle until a p-wave appears with no QRS |
Second Degree Block Type II PRI | Normal, or slightly prolonged but constant for conducted beats |
Second Degree Block 2:1 Conduction PRI | Constant |
Third Degree Block (Complete Block) PRI | None- the atria and Ventricles beat independently of each other, thus there is no true PRI |
