Prepotential preceding the surface QRS by 35 milliseconds was recorded at the ablation site during VT (Figure 3(a)).
Caption: Figure 3: (a) Intracardiac electrogram showing bipolar prepotential preceding the surface QRS by 35 milliseconds (arrow) and unipolar QS pattern (asterisk) recorded at the ablation site during ventricular tachycardia.
In this paper we advocate and develop the use of the dreibein or triad (the 3D version of the vielbein) as the basic variable or prepotential
for Yang-Mills theory.
Beta-adrenergic agonist (isoproterenol) stimulation of the patient-specific iPSC-derived cardiomyocytes caused delayed afterdepolarization, arrhythmogenic oscillating prepotentials
, and postcontractions.
Evidence for dendritic origin of spikes without depolarizing prepotentials
in hippocampal neurons during and after seizure.
In reduced preparations consisting of the tail connected by its nerves to the central nervous system, stimulation of the tail with a glass probe activated a barrage of action potentials with no prepotentials
([ILLUSTRATION FOR FIGURE 3D OMITTED]; similar results observed in two additional preparations).
