This can be related to the phenomenon of loss of alpha activity and prominence of delta waves found in encephalopathy.
Post-operative course was favourable and subsequent ECG revealed disappearance of delta wave.
The predictive accuracy for Arruda algorithm based on delta wave was found to be significantly higher as compared to Taguchi algorit hm based on R/S ratio (p 0.01).
The patient opted for ablation therapy, which successfully eliminated the delta wave on EKG.
Although the ECG mimics RBBB, a more careful inspection of the baseline ECG indeed reveals a small delta wave and relatively short PR interval.
For all the phases of [f.sub.1], [f.sub.2], and [f.sub.3], Alpha waves ([B.sub.1]) are decreased significantly and transferred into Theta wave ([B.sub.3]) and Delta wave ([B.sub.4]) standing for the slights sleeping status.

Whereas delta wave brain activity seems to be modulated by the cholinergic transmitter system, theta brain activity is related to the neurotransmitter, noradrenaline.
A team at the University of Illinois (Chicago) has zeroed in on a negative slow wave (Delta wave), isolating it as an event related potential with the ability to pop up 150 to 500 milliseconds before a particular playing card (with which it was previously associated) is applied, indicating that human subjects may be able to anticipate or prognosticate that about which they are about to see when in fact they have no way of knowing what image, color or other indica will be shown to them.
