Enhanced response of blood monocytes to in vitro lipopolysaccharide-challenge in patients with recurrent unstable angina.

abstract：BACKGROUND:Current methods of signal-averaged ECG analysis interrogate the terminal 40 msec of the QRS complex and/or the ST segment and have a low positive-predictive accuracy for detecting vulnerability to sustained ventricular tachycardia (VT). The extent to which abnormalities detected during these ECG intervals ar...
