OBJECTIVES The main objective of this study was to characterize the phenomenon of variation in the P-QRS relation during atrioventricular node reentry tachycardia. BACKGROUND Variation of P-QRS relation during tachycardia has been observed occasionally in atrioventricular node reentry tachycardia. However, the incidence, the characteristics and the(More)
Postconditioning (PosC), which is a brief period of ischemia performed at the time of reperfusion therapy, reduces the infarct size in animal models. We aim to evaluate the impact of PosC in patients with ST-elevation acute myocardial infarction (STEMI). Between January 2008 and August 2009, 37 STEMI patients received PosC. The control group comprised 42(More)
INTRODUCTION Fast-intermediate form AV nodal reentry tachycardia (AVNRT) sometimes may mimic atrial tachycardia or atrial flutter and render the diagnosis difficult when the tachycardia rate is fast and AV block occurs during tachycardia. METHODS AND RESULTS A 45-year-old woman with paroxysmal supraventricular tachycardia was referred to this institution.(More)
Clinical and electrophysiologic parameters were analyzed to define the factors potentially related to tachycardia recurrences in 79 patients undergoing successful radiofrequency ablation of idiopathic right or left ventricular tachycardia. It was found that the endocardial activation time at the successful ablation site was the only independent predictor of(More)
Catheter-induced aortocoronary dissection is a rare, but serious complication during diagnostic coronary catheterization or percutaneous coronary intervention (PCI). Immediate coronary artery stenting of the entry point is one of therapeutic options. However, PCI itself may worsen the dissection, because contrast injection has been reported to be a risk(More)
Acute aortic dissection (AAD) causes transient inflammation with occasional pleural fluid (PF) accumulation. Although pentraxin 3 (PTX3) is a vascular inflammation-related biomarker, little is known about PTX3 levels in patients with AAD. We explored the serial changes in plasma PTX3 levels and the association of peak levels with the amount of PF(More)
BACKGROUND Peripheral venoarterial extracorporeal membranous oxygenation (ECMO) support is effective in patients with cardiogenic shock or fatal arrhythmia due to fulminant myocarditis. The clinical courses of fulminant myocarditis are still uncertain; therefore, it is difficult to determine the appropriate time for discontinuing ECMO or converting to a(More)
SUMMARY Distortion analysis of nonlinear circuits is very important for designing analog integrated circuits and communication systems. In this letter, we propose an efficient frequency-domain approach for calculating frequency response curves, which is based on HB (harmonic balance) method combining with ABMs (Analog Behavior Models) of Spice. Firstly,(More)
We present a case of a patient who needed rapid switch from intra-aortic balloon pumping (IABP) to percutaneous cardiopulmonary support (PCPS)/venoarterial extracorporeal membrane oxygenation. It is difficult to switch from IABP to PCPS, because 0.035-inch guidewires cannot pass the IABP guidewire lumen (0.025-inch compatible), and the IABP sheath needs to(More)
It is of utmost importance to minimize the door-to-balloon time for the initial treatment of ST-elevation acute myocardial infarction. In this case report, we made all kinds of efforts to minimize procedures in the emergency department (ED minimization) as well as in the catheter laboratory without sacrificing safety.
