Randomized Controlled Trial Multicenter Study Comparative StudyDynamicity of the J-wave in idiopathic ventricular fibrillation with a special reference to pause-dependent augmentation of the J-wave.
This study evaluated the pause-dependency of the J-wave to characterize this phenomenon in idiopathic ventricular fibrillation (VF). ⋯ Pause-dependent augmentation of J waves was confirmed in about one-half of the patients with idiopathic VF after sudden R-R prolongation. Such dynamicity of J waves was specific to idiopathic VF and may be used for risk stratification.

Randomized Controlled Trial Multicenter Study Comparative StudyIntraprocedural thrombotic events during percutaneous coronary intervention in patients with non-ST-segment elevation acute coronary syndromes are associated with adverse outcomes: analysis from the ACUITY (Acute Catheterization and Urgent Intervention Triage Strategy) trial.
The purpose of this study was to assess the prognostic impact of intraprocedural thrombotic events (IPTE) during percutaneous coronary intervention (PCI). ⋯ Although infrequent among patients undergoing early PCI for moderate and high-risk non-ST-segment elevation acute coronary syndrome, IPTE was strongly associated with subsequent adverse outcomes including death, myocardial infarction, and stent thrombosis.
