Functional properties of accessory AV pathways during premature atrial stimulation.

Premature atrial stimulation was performed during His bundle recording in four patients with the type of ventricular pre-excitation in which theforward H deflection appeared after the onset of the delta wave. The AV conduction patterns occurring in these patients seemed to have depended on the physiological differences existing between normal pathway and accessory pathway (AP) at different mome...

Concealed conduction of premature ventricular complexes resulting in AV nodal block

.

His bundle recordings in bradycardia-dependent AV block induced by premature beats.

Symptomatic bradycardia-independent atrioventricular block occurred in a patient with right bundle-branch block, left anterior hemiblock, and prolonged HV interval. The arrhythmia, triggered by a spontaneous or induced premature beats, appeared when the post-extrasystolic PP and HH intervals increased to a critical value. Reinitiation of atrioventricular conduction required the presence of vent...

Some characteristics of transmembrane potentials of AV nodal cells during propagation of premature beats.

Utvikling av altruisme med gjenkjennelse av slektskap i evolusjonære roboter

Swarm robotics provides ways of solving problems using groups of autonomous robots that display emergent intelligent behaviour. Control mechanisms for these robots can be designed by using mechanisms from evolutionary robotics. In order to ensure that the controllers are adaptive and capable of learning new behaviour controllers are artificially evolved using techniques inspired by natural evol...
