TL;DR: Electrical activity from the entire ventricular epicardium of human hearts is mapped to establish the relative roles of the mother rotor and multiple wavelet mechanisms of VF, which do not appear to be mutually exclusive in the human heart.

TL;DR: It is demonstrated that myocardial ischaemia induced by incremental atrial pacing in patients with coronary artery disease causes an acute increase in QT dispersion, which may prove more useful than resting QT Dispersion in assessing the individual risk of arrhythmic events.

TL;DR: The adrenergic agonists isoprenaline and adrenaline increased the steepness of the slope of the APD restitution curve in humans over a wide range of diastolic intervals, which may relate to the known effects of adrenergic stimulation in facilitating ventricular fibrillation.

TL;DR: Across patients, heartbeat-evoked potential amplitude at left temporal and lateral frontal electrode locations correlated with stress-induced changes in cardiac output, consistent with an afferent cortex representation of myocardial function during stress, delineate a cortical representation of cardiac function predictive of proarrhythmic abnormalities in cardiac repolarization.

TL;DR: Plasma-samples have been taken from racing drivers at various times within a three-hour period following a race to provide an example of an extreme emotional and aggressive situation, associated with minimal physical effort, to demonstrate magnification of certain biochemical changes that may occur in everyday life.
