[Shock caused by electrical current].

The authors elaborate the most frequent causes of electroshock and consequences to the human body thereof. Recent advances in modern medical technology increase the hazard of the electroshock. Tissue burns, asphyxia, CNS destruction and ventricular fibrillation are possible consequences. Depending on the electric current strength, the organism may be a subject of either a macroshock or a microshock. The methods of microshock prevention in hospital environment are disclosed. Two patients are presented, being treated at the Institute of Anesthesiology and Intensive Care.

[Atrio-biventricular electrostimulation in the treatment of congestive heart failure. Case report].

Over the past few years, indications for permanent cardiac pacing have been broadened. Accordingly, American Heart Association and American College of Cardiology included dilated cardiomyopathy, hypertrophic obstructive cardiomyopathy and pacing for prevention of atrial fibrillation into indications for permanent cardiac pacing. Studies have described favourable effect of dual chamber cardiac pacing in congestive heart failure in dilated cardiomyopathy, regardless of etiology. In the past two years, even more beneficial effect was associated with multisite, biventricular cardiac pacing. On the basis of the reported results, a multisite pacemaker InSync was implanted to a patient with dilated cardiomyopathy (NYHA class IV), who was also on the list for heart transplantation, and who fulfilled other criteria for implantation of multisite pacemaker. During the eleven-month follow-up, functional improvement, better 6-minute walking test and enhanced quality of life of the patient were observed, which is in accordance with the literature data.

[Management of surgery patients with implanted cardiac pacemakers].

Patients having cardiac pacemaker implanted may be subjected to various general surgery procedures. Application of electrosurgery for the purpose of resection and coagulation, provides a high frequency electric field which produces electric voltage on the electrodes of the pacing system. This voltage may be detected within the pacing system, and various arrhythmias can be provoked in correlation with underlying rhythm and mode of pacing. Preoperative patient control and proper pacemaker programming can prevent the pacing malfunctions due to the electrosurgery application. Appropriate positioning of the neutral electrode in relation to the pacing system avoids the electric fields intersection and decreases their interference.
