RESULTS. Mean time from ExECG to vs-CMR was 88.69±84.32 days and 37 vs-CMR were positive for ischemia. Male sex, less exercise time, less % of maximum predicted exercise capacity, less maximum double product (heart rate x systolic blood pressure) and less double product reserve (DPR = ...
1、Electrocardiogram (ECG,Myocardial Ischemia and Infarction,What clinical problems can be predicted by an ECG,Insufficient blood flow and death of cardiac muscle due to a blood clot. The primary method for identifying problems with heart rate and regularity. Electrical conduction blocks. Enlargement ...
Objective To improve the exercise ECG analysis for non invasively detection of myocardial ischemia. Method The newly developed measuring system of exercise ECG defines ST segment area and STA/HR slope as the new characteristic parameters,thus can sensitively detect myocardial ischemia. Some methods were...

strong correlation. The CEBappears to show a stronger response to balloon inflation in larger arteries, cases involving infarction, and in greater severity stenosis. The CEBmay be an efficient and timely means of detecting myocardial ischemia in patients who are being monitored in acute care ...

Patients with unstable coronary syndromes are a heterogeneous group with varying degrees of ischemia and prognosis. The present study compares the ...
18、h for coronary and noncoronary causes ,with or without ECG changes Acute or evolving ischemia are often masked by the presence of LEBBB,WPW,electronic ventricular pacemaker patterns Q wave includes ventricular hypertrophy, hypertrophic cardiomyopathy,心肌梗死(myocardial infarction),基本图形:缺血型、...
(PCA) was used with neural network. Ischemia is an ECG waveform having a small positive J peak between ST segments. The method was trained with 1000 samples of ST-T database and achieved 90% of recognition rate in detecting ischemia11. Also, in 1999, Z. Dokur et al. gave a ...
Changes in the waveform may indicate certain cardiovascular events, such as myocardial ischemia or electrolyte abnormalities, which require immediate examination, diagnosis, and treatment by the anesthesiologist. T waves are often elevated in children, and blood may be drawn for suspected abnormalities. ...
The interpretation of the amplitude and duration of these lines allows for the assessment of normal cardiac physiology as well as the detection of cardiac arrhythmias, conduction system abnormalities, and/or ischemia. This article provides an overview of the most essential components of the ECG ...
