Anotācija Cardiosynchronous transcutaneous electrical nerve stimulation device is a new technology. In our studies to test the concept of new electrostimulator, we used electrical nerve stimulation 200ms after R-wave with 125ms long bipolar pulse package to decrease Rate - Pressure product, as previously it was proved in preliminary experiments. The aim of the present study is technical elaboration of the innovative ECG R-wave triggered transcutaneous nerve stimulation prototype device to further perform the feasibility studies of such a neurostimulation technology. Recent studies have demonstrated that augmentation of the sympathetic activity can be reduced if the intermittent sensory stimulation impulse is applied during each cardiac cycle with the time delay 200-400ms after ECG R-wave. Moreover previous pilot study showed that applying of such a cardio synchronous stimulation mode to the afferent nerve endings in human canal result in significant lowering of arterial systolic blood pressure if the initial arterial pressure values were elevated. Up to now there is no such noninvasive neurostimulation device with being able to decrease high sympathetic neural system activity and myocardial oxygen consumption. There is a TENS device developed by CardioLa. The device stimulates skeletal muscles and makes heart load easier by additional pumping of blood due to caused contractions. It is not possible to use it in long term because muscles get tired. Therefore a stimulator for long term use is needed.
