Postextrasystolic Changes in the Complexity of the QRS Complex and T Wave [PDF]
Annals of Noninvasive Electrocardiology, 2008 We tested the hypothesis that ventricular repolarization of the first sinus beat following a ventricular premature beat (VPB) can be modulated in the absence of clearly discernible T‐wave changes. We applied principal component analysis (PCA) to assess QRS and T‐wave complexity of sinus beats preceding and following VPBs in multiple 10‐second resting ...

REACTIVITY OF CHLOROPHYLL a/b-PROTEINS AND MICELLAR TRITON X-100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]
, 1989 The reaction of several plant chlorophyll-protein complexes with NaBH4 has been studied by absorption spectroscopy. In all the complexes studied, chlorophyll b is more reactive than Chi a, due to preferential reaction of its formyl substituent at C-7 ...

Wide QRS complex tachycardia [PDF]
Circulation, 2017 A 71-year-old man with a history of previous myocardial infarction was referred to our hospital for recurrent symptoms of palpitation and syncope. During an episode of palpitations, a 12-lead ECG (Figure 1) was obtained in the emergency room. The ECG shows a wide-QRS complex tachycardia at a rate of 167 bpm.
