[Myopotentials and unipolar cardiac stimulation. Asynchronous conversion of generators].
During routine control of unipolar demand pacemakers (SSI) and the myopotential effects by means of chest wall stimulation (CWS) we have observed a non-inhibition and a pacemaker asynchronous conversion. With the arm recovery this phenomenon disappears. A concealed effect of myopotentials is possible. This is an effect depending on anti-interference function (EMI) of demand pacemakers. Chest wall stimulation analysis is an additional technique for a complete study of muscular activity effects.
