2nd degree AV block with junctional escapes and captures | Second degree AV block is present; conducted beats are identified by those QRS's that terminate shorter cycles than the junctional escape cycle; i.e., the 3rd and probably the 4th QRS's are captures; the other QRS's are junctional escapes. | Knowledge Weavers ECG | |

2nd degree AV block, type I | The 3 rules of classic AV Wenckebach are: 1. decreasing RR intervals until pause; 2. the pause is less than preceding 2 RR intervals; and 3. the RR interval after the pause is greater than the RR interval just prior to pause. Unfortunately, there are many examples of atypical forms of Wenckebach wh... | Wenckebach AV Block | Knowledge Weavers ECG |

 |
Atrial echos | In this example a typical Wenckebach sequence is interrupted by what looks like a PAC - indicated by red arrows. Atrial echos are more likely, however, because the preceding beat has a long PR interval, a condition that facilitates reentry and echo formation. | Knowledge Weavers ECG | |

Two Wrongs Sometimes Make a Right | The question mark is over a normal looking QRS that occurs during 2:1 AV block with RBBB. Following this QRS a ventricular escape rhythm takes over. The normal looking beat is actually a fusion beat resulting from simultaneous activation of the ventricles; the sinus impulse enters the left ventric... | Knowledge Weavers ECG | |

 |
WPW type preexcitation | Note the short PR and the subtle delta wave at the beginning of the QRS complexes. The delta wave represents early activation of the ventricles in the region where the AV bypass tract inserts. The rest of the QRS is derived from the normal activation sequence using the bundle branches. | Knowledge Weavers ECG | |
| 1317 |
 |
Long QT interval | The QT interval duration is greater than 50% of the RR interval, a good indication that it is prolonged in this patient. Although there are many causes for the long QT, patients with this are at risk for malignant ventricular arrhythmias, syncope, and sudden death. | Knowledge Weavers ECG | |

Wandering atrial pacemaker | Wandering atrial pacemaker is a benign rhythm change where the pacemaker site shifts from the sinus node into the atrial tissues. P-wave morphology varies with the pacemaker site. | Knowledge Weavers ECG | |

PAC's with RBBB aberrant conduction | PAC's are identified by the arrows. Note that the PP interval surrounding the PAC is less than 2x the basic sinus cycle indicating that the sinus node has been reset by the ectopic P wave. The pause after the PAC, therefore, is incomplete. | Knowledge Weavers ECG | |
| 1325 |
 |
1st degree AV block | The normal PR interval is 0.12 - 0.20 sec, or 120 -to- 200 ms. 1st degree AV block is defined by PR intervals greater than 200 ms. This may be caused by drugs, such as digoxin; excessive vagal tone; ischemia; or intrinsic disease in the AV junction or bundle branch system. | Knowledge Weavers ECG | |
| 1326 |
 |
Sore thumbs | Two funny looking premature beats are seen in this rhythm strip. Beat A is preceded by a PAC which distorts the T wave, making this an aberrantly conducted PAC. Beat B is a PVC.

 |
AV dissociation by default | If the sinus node slows too much a junctional escape pacemaker may take over as indicated by arrows. AV dissociation is incomplete, since the sinus node speeds up and recaptures the entricles. | Knowledge Weavers ECG | |

RBBB with primary ST-T wave abnormalities | RBBB is recognized by 1) rR' in V1; 2) QRS duration>0.12s; 3) terminal QRS forces oriented rightwards and anterior.

What are those funny looking beats???? | The differential diagnosis of funny-looking-beats, or FLB's, primarily considers beats of supraventricular origin with aberrant conduction and ventricular ectopic beats. In this example the two FLB's have an easily seen ectopic P wave before them; therefore these are PAC's with RBBB aberration. | Knowledge Weavers ECG | |
