results: the average of dyssynchrony in eight cycles showed a positive correlation with dyssynchrony in target beat rr1/rr2 = 1. average of dyssynchrony in target beat was 46.77 msec, and average of 8 cycle was = 47.701, (p value = 0.776, pearson linear correlation 0.769). objectives: we proposed to evaluate intraventricular mechanical dyssynchrony by measuring time-to-peak systolic velocity be...

was found in 22 of 24 subjects with myocardial infarction and 14 patients without documented myocardial infarction. A close linear correlation (r = -0.82, P < 0.001) was noted between shortening of the QS2I and catecholamine excretion among all patients irrespective of the presence of documented infarction. Patients with serious arrhythmias had significantly higher levels of catecholamine excre...

We construct a sequence of closed hyperbolic surfaces that are local maxima for the systole function in their respective moduli spaces. Their is arbitrarily large and number examples grows rapidly with genus. More precisely, every $n\\geq 3$ there some positive $L_n$ (growing roughly linearly $n$) such genus $g$ equal to super-exponentially along an arithmetic step size $n$. Many these have no ...

BACKGROUND Myocardial blood flow (MBF) varies throughout the cardiac cycle in response to phasic changes in myocardial tension. The aim of this study was to determine if quantitative myocardial perfusion imaging with cardiovascular magnetic resonance (CMR) can accurately track physiological variations in MBF throughout the cardiac cycle. METHODS 30 healthy volunteers underwent a single stress...

Abstract We show that the length R of a systole closed hyperbolic n -manifold $$(n \ge 3)$$ ( n ? 3 ) admitting triangulation by t -simplices can be bounded below function and , namely $$\begin{aligned} \frac{1}{2^{(nt)...
