Journal of Family Medicine and Primary Care, 2018 Acute coronary syndrome (ACS) is a term used to describe a spectrum of diseases associated with sudden reduced blood flow to the heart. Coronary artery thromboembolism is recognized as an important nonatherosclerotic cause of acute myocardial infarctions in 2.9% of ACS cases, with a long-term outcome indicating that coronary embolism patients represent

Atypical atrial flutters [PDF]
Europace, 2002 Typical atrial flutter is due to a counterclockwise macro-re-entry circuit localized in the right atrium with a surface ECG pattern showing predominantly negative F waves in the inferior leads and positive F waves in V1. Recently it has been proposed to classify atrial flutter on the basis of its cavo-tricuspid isthmus dependence rather than on the ECG

Calculation of AGARD Wing 445.6 Flutter Using Navier-Stokes Aerodynamics [PDF]
, 1993 An unsteady, 3D, implicit upwind Euler/Navier-Stokes algorithm is here used to compute the flutter characteristics of Wing 445.6, the AGARD standard aeroelastic configuration for dynamic response, with a view to the discrepancy between Euler ...

AEROELASTIC FLUTTER ANALYSIS OF SUPERSONIC WING WITH MULTIPLE EXTERNAL STORES
International Islamic University Malaysia Engineering Journal, 2014 : Flutter may be considered to be one of the most dangerous aeroelastic failure phenomenon. The flutter characteristic differs for each aircraft type, and depends on the wing geometry as well as its operational region of subsonic, transonic or supersonic

Flutter Speed Limits of Cantilever Rectangular and Tapered Plates
Al-Khawarizmi Engineering Journal, 2007 The aerodynamic and elastic forces may cause an oscillation of the structure such as the high frequency of the airfoil surfaces and the dynamic instability occurring in an aircraft in flight and failure may occur at a speed called flutter speed.

Atrial fibrillation and its determinants after radiofrequency ablation of chronic common atrial flutter [PDF]
, 2005 Aim. Atrial fibrillation (AFib) is a major clinical issue and its occurrence is the main problem after catheter ablation of atrial flutter. The long-term occurrence of AFib after common atrial flutter ablation is still matter of debate as it may ...
