心力衰竭本质上是收缩性的(Systolic in nature),属于低输出量类型(Of the low output variety),起源于双心室(Biventricular in origin)。 心电图显示窦性心动过速(Sinus tachycardia)、窄QRS波群(Narrow QRS complexes)和非特异性T波倒...
Subjects 21 patients (11 with coronary artery disease, 10 with idiopathic dilated cardiomyopathy) with end diastolic dimension > 6.4 cm, shortening fraction< 25%, and in sinus rhythm. There were 11 age matched normal controls. Results In the patients, peak oxygen consumption (mV˙o 2) ...

Multifactorial determinants of reduced coronary flow reserve after dipyridamole in dilated cardiomyopathy Coronary sinus blood flow (ml/100 g left ventricular [LV] mass/min) and coronary resistance (mean aortic minus LV mean diastolic pressures/coronary sinus b...

cardiomyopathy is not completely understood, however development of a coronary thrombus, increased oxida- tive stress, calcium flux sympathomimetic effects are contributing factors in its pathophysiologic formation [6]. The duration and quantity of cocaine use required to develop a subsequent cardiomyopathy...
Results from other tests and procedures such as a coronary angiogram, echocardiogram, multiuptake-gated acquisition, electrocardiogram, 24-hour ECG recording (commonly referred to as a "Holter monitor"), endo- cardial biopsy, and others should be documented. Assessment for possible syndromic forms of...
All patients were in normal sinus rhythm except one who had atrial fibrillation at entry and at follow-up examination. Significant coronary disease was excluded by stress thallium in two patients and coronary angiography in 11 patients. Seven of these patients had normal coronary angiograms, two ...
Exclusion criteria were presence of rhythms other than sinus rhythms in electrocardiography (ECG), pacemaker implan- tation, coronary artery disease (obstruction > 50% of the luminal diameter in a major branch), valvular heart dis- eases, and congenital heart diseases. Fifty-nine healthy volunteers...
