PVC with venticular echo | The PVC in this example retrogradely enters the AV junction and returns, usually down a different pathway, to reactivate the ventricles....a ventricular echo. This is unlikely to be an interpolated PVC because the PR interval following the PVC is too short for the sinus impulse to have entered the ... | Knowledge Weavers ECG | |

Left bundle branch block (LBBB) | LBBB is recognized by 1) QRS duration>0.12s; 2) monophasic R waves in I and V6; and 3) terminal QRS forces oriented leftwards and posterior. The ST-T waves should be oriented opposite to the terminal QRS forces. | Knowledge Weavers ECG | |

Fatty acid elongation in mitochondria | This shows the overall reaction of fatty acid elongation in mitochondria. The process is essentially a reversal of beta-oxidation, except that one NADPH and one NADH are required (beta-oxidation yields two NADH). Mitochondrial fatty acid elongation acts primarily on fatty acyl CoA substrates short... | Knowledge Weavers Fatty Acids | |

Ventricular tachycardia with retrograde wenckebach | Approximately 50 percent of ventricular tachycardias are associated with AV dissociation. The other 50 percent have retrograde atrial capture. This example shows ventricular tachycardia with retrograde Wenckebach. The retrograde P waves are hard to find, but the arrows are of some help. | Wenckebach AV Block | Knowledge Weavers ECG |

Nonconducted and aberrantly conducted PAC's | In A the slow sinus rhythm is actually caused by nonconducted PACs hidden in the ST segment. This is confirmed in B where some of the PACs are aberrantly conducted with LBBB, and some PACs are nonconducted. | Knowledge Weavers ECG | |

Left anterior fasicular block: frontal plane leads | Left anterior fascicular block, LAFB, is recognized by left axis deviation of -45 degrees or greater; rS complexes in II, III, aVF; and a small Q wave in I and/or aVL. | Knowledge Weavers ECG | |
