102 Ventricular pacemaker rhythmNote the small pacemaker spikes before the QRS complexes in many of the leads. In addition, the QRS complex in V1 exhibits ventricular ectopic morphology; i.e., there is a slur or notch at the beginning of the S wave, and>60ms delay from onset to QRS to nadir of S wave. This rules against a suprav...Knowledge Weavers ECG
103 Acylation of carnitine by a long chain fatty acyl CoALong chain fatty acyl CoA cannot cross the inner mitochondrial membrane to participate in beta-oxidation. The fatty acyl group is therefore transferred to a carrier, carnitine, in a reversible reaction catalyzed by carnitine acyl transferase I. The resulting fatty acyl carnitine crosses the membra...Knowledge Weavers Fatty Acids

111 ECG of the century: A most unusual 1st degree AV blockOn Day 1, at a heart rate of 103 bpm the P waves are not clearly defined suggesting an accelerated junctional rhythm. However, on Day 2, at a slightly slower heart rate the sinus P wave suddenly appears immediately after the QRS complex. In retrospect, the sinus P wave in Day 1 was found burried i...Knowledge Weavers ECG
112 RBBB plus mobitz II 2nd degree AV blockThe classic rSR' in V1 is RBBB. Mobitz II 2nd degree AV block is present because the PR intervals are constant. Statistically speaking, the location of the 2nd degree AV block is in the left bundle branch rather than in the AV junction. The last QRS in the top strip is a junctional escape, since...Knowledge Weavers ECG
113 Left axis deviation: QRS axis = -60 degreesLead aVR is isoelectric; leads II and III are mostly negative. The QRS axis, therefore, is -60 degrees.Knowledge Weavers ECG
114 QRS axis = +30 degreesLead III is isoelectric; leads I and II are positive. The QRS axis, therefore, is +30 degrees.Knowledge Weavers ECG
115 methylmalonyl CoA racemase reactionIn the metabolism of propionyl CoA, D-methylmalonyl CoA is produced by a carboxylase reaction. This product must be converted to L-methylmalonyl CoA in order to be metabolized further. The conversion is catalyzed by methylmalonyl CoA racemase.Knowledge Weavers Fatty Acids

120 Type II, 2nd degree sino-atrial blockTwo types of 2nd degree SA block have been described. In type-I, or SA Wenckebach, the P-P interval of the pause is less than 2x the preceding P-P intervals. In type-II SA block the P-P interval of the pause is approximately 2x the normal P-P interval. The distinction between types I and II is no...Knowledge Weavers ECG
121 Bradycardia-dependent LBBB with carotid sinus massageWhen carotid sinus massage slows the heart rate in this example, the QRS widens into a LBBB. This form of rate-dependent bundle branch block is thought to be due to latent pacemakers in the bundle undergoing phase 4 depolarization; when the sinus impulse enters the partially depolarized bundle, slow...Knowledge Weavers ECG
122 Atrial tachycardia with 3:2 AV blockIn this rhythm the atrial rate from an ectopic focus is 160 bpm. Atrial activity can be seen on top of T waves, and before QRS's. Careful observation reveals a 3:2 Wenckebach relationship between P waves and QRS's. Atrial tachycardia with block is often a sign of digitalis intoxication.Knowledge Weavers ECG
123 Ventricular fusion beatsFusion beats occur when two or more activation fronts contribute to the electrical event. These may occur in the atria or in the ventricles. In this example the ventricular fusions are the result of simultaneous activation of the ventricles from two foci, the sinus node and a ventricular ectopic...Knowledge Weavers ECG
124 enoyl CoA isomerase reactionEnoyl CoA isomerase converts a trans-3-enoyl CoA to a trans-2-enoyl CoA. Thus a Delta-9 fatty acyl CoA or the product of the 2,4-dienoyl CoA reductase reaction can proceed through beta-oxidation.Enoyl CoA Isomerase ReactionKnowledge Weavers Fatty Acids
