Low-level vagosympathetic stimulation: a paradox and potential new modality for the treatment of focal atrial fibrillation.
BACKGROUND We used high-frequency stimulation delivered during the refractory period of the atrium and pulmonary veins (PVs) to induce focal firing and atrial fibrillation (AF). This study was designed to demonstrate that bilateral low-level vagosympathetic nerve stimulation (LL-VNS) could suppress high-frequency stimulation-induced focal AF at atrial and PV sites. METHODS AND RESULTS In 23 d...
متن کاملMuscarinic effects of vagosympathetic trunk stimulation on the repetitive extrasystole (RE) threshold.
The precise mechanism of the vagus in opposing adrenergic influences on cardiac vulnerability has not been defined. In the present investigation, cholinergic stimulation was produced by administering the selective muscarinic agent methacholine (MCh) and ventricular vulnerability was assessed by measuring the repetitive extrasystole (RE) threshold. MCh produced a sustained 98 +/- 12% (P less tha...
متن کاملResponses of individucal cardiac chambers to stimulation of the cervical vagosympathetic trunk in atropinized dogs.
Employing multiple chamber pressure recording techniques, the presence of fibers within the right and left cervical vagosympathetic trunks which innervate both right and left ventricles has been demonstrated. Electrical excitation of the cervical vagosympathetic in the atropinized dog elicited a distinct increase in both rate of rise and in maximal systolic intraventricular pressures, with or w...
متن کاملEffect of Low-Level Laser Stimulation on EEG
Conventional laser stimulation at the acupoint can induce significant brain activation, and the activation is theoretically conveyed by the sensory afferents. Whether the insensible low-level Laser stimulation outside the acupoint could also evoke electroencephalographic (EEG) changes is not known. We designed a low-level laser array stimulator (6 pcs laser diode, wavelength 830 nm, output powe...
