Abstract

In conditions of operative procedure, resulting from the competent actions of surgeon and anaesthesiologist, there appears an excessive slowing down of the heart rate, which causes tissue flow disturbances and a drop of arterial blood pressure. This impairment of haemodynamics has a negative influence on course of operative procedure and, later, the patient’s life after the operation. Excessive reduction of heart rate during the operative procedure, performed in general anaesthesia, having negative haemodynamic effects, appears very often - in up to 30–70% of operated patients.
No or delayed reaction to the pharmacological treatment applied in this situation negatively influences life of those patients especially, in whom damage to the key organs had already appeared before operation. The introduction of stimulation using an invasive method is, in the conditions of an operating room, very difficult and practically impossible because of no trained cardiologists present there.
A positive solution in the situation mentioned above is to equip the anaesthesiologist with a non-invasive stimulator and transoesophageal electrode, which he can insert into the oesophagus, beginning heart stimulation in each case of too excessive slowing down of the heart rate. This anaesthesiological, non-invasive heart stimulator makes possible the quick introduction of atria or heart ventricles stimulation, correcting decreased heart rate and preventing prolonged disturbances of the tissue flow. The efficacy of this procedure is easier because of the specially anatomically formed anaesthesiological oesophageal electrode. The electrode allows us to perform both quick and safe insertion of the electrode into the oesophagus near the heart as well as to obtain 100% efficacy in atria stimulation and 98% efficacy of heart ventricles stimulation. The applied solutions of anaesthesiological stimulator and anaesthesiological electrode also provide a stable operating field during heart stimulation.
