root-mean-square curveAccurate detection of the earliest signs of ischemia on the surface electrocardiogram (ECG) is essential for timely diagnosis and management of potentially life-threatening ischemic events. Yet, accuracy of ischemia analysis in ECG monitors remains suboptimal because of a number ...
We included aged > 18 years old patients who were diagnosed with myocardial ischemia based on cardiovascular risk profiles, clinical ischemic symptoms and/or signs, and electrocardiogram (ECG) findings and whose coronary stenosis < 50% (including 0% stenosis) in all epicardial arteries and...
The data were obtained on admittance and at follow-up after 3 months. The majority (93.2 and 93.3%) of both groups were male, and the mean age was significantly higher in Group B [52.59 ± 9.72 vs. 59.09 ± 11.54, P = 0.005]. There was no difference in their ...

Objective The aim of this investigation is to study the relationships between QT or QTc and ischemia or autonomic nervous system condition.Methods 52 patients with episodic ST depression in ambulatory ECG were included,37 men and 15 women,mean age was 60±10 years (41～82).Results The data sh...
The criteria includes the presence of: (1) positive ischemic cardiac biomarkers and corroborative clinical evidence of infarction (clinical symptoms, ECG ST segment changes, LBBB, or pathologic Q waves, and loss of myocardial viability); (2) non-obstructive coronary arteries on angiography (no ...
Conclusion: The BSPM lead locations for effective detection of myocardial infarction by evaluation of the ST segment as well as the T- wave were proposed. These locations are mostly outside the conventional 12-lead ECG recording sites. 展开 年份: 2006 ...
The asymptomatic episodes lasted for a mean of 1.B±1.3 min (mean±S.D.), while the symptomatic episodes lasted 3.B±2.7 min (p<0.002 by sign test). Heart rate was unchanged during the episodes of TMI and did not show any significant difference between asymptomatic and symptomatic ...
Ten hearts from New Zealand White male rabbits (mean [±SD] weight 4.02 ± 0.26 kg) were investigated. Rabbits were anesthetized with intravenous pentobarbital (50 mg/kg body weight), and hearts were isolated, mounted on a vertical Langendorff apparatus (Fig. 1) and perfused as previously desc...
Regional ischemia was confirmed by the elevation of the S-T segment on the electrocardiogram (ECG) and visual inspection of discoloration of the occluded distal myocardium. After 30 min of ischemia, the ligation was released, and the heart allowed to be repercussed as confirmed by visual ...
