In this paper, a conformance
test platform is built for intelligent electronic devices (IEDs) from different
manufacturers based on IEC 61850 communication protocol. A conformance test of
time delay of message transmission between two IEDs, made by the same or
different manufacturers, is performed. The conformance test platform, as well
as the test results provide a helpful reference for IEC 61850 implementation.
Pericarditis and hemopericardium
causing cardiac tamponade, caused by large and transmural ventricular
infarction with subsequent rupture into the pericardium, is a rare complication
post acute myocardial infarction. This is frequently fatal with rapid clinical
course. We reported a 65-year-old female who presented with persistent diaphoresis
and dyspnea for several hours followed by syncope. Acute myocardial infarction was
diagnosed with primary percutaneous coronary intervention performed though persistent
hypotension was observed. Moderate amount
of hemopericardium leading to tamponade was found. It was relieved after pericardiocentesis.
Real-time three-dimensional echocardiography revealed blood clot with specific
whirling pattern around the infracted ventricular wall with suspected leak.
