[Development of pacemaker implantation].

The Morgagni-Adams-Stokes syndrome and the possibility of the excitability of a heart standing still by electric current are already known for a long time. Nevertheless, only in 1952 first success in the treatment in man was seen. In 1958 the first transistorized, working with battery cardiac pacemakers were implanted. The development of the impulse supply for the permanent and temporary stimulation, of the infloating technique, of the impulse production, the source of energy and the working method are demonstrated. In a tabulated survey the comparison of the cardiac pacemakers which are annually implanted in the GDR with those ones in the County Hospital St. George Leipzig is done.

[Extraction of the electrodes by continuous traction--an effective procedure in treating pacemaker wearers with secondary inflammatory complications].

Using a continuous traction method we succeeded in extracting 24 bacterially contaminated and fixed in the heart electrodensounds around 4 years after pacemaker implantation without complications worth mentioning in 7.5 days (1-27). The tissue attached to 20 sound points contained 9 times portions of the myocardium, 9 times remainders of the endocardium, 12 times particles of the connective tissue and 17 times suppurative inflammatory tissue. After extraction of the sound and aimed chemotherapy in all 24 patients the inflammatory pathological conditions rapidly and free from recidivations receded.

[Multicenter study of the results of the extraction of transvenously implanted heart-pacemaker electrodes using continuous traction].

The continuous traction of firmly grown-in collar electrodes from the right ventricle is a simple technique poor in complications with a high success rate, which can be recommended taking into consideration the indications in the failure of the immediate manual extraction and which can be performed in every centre for cardiac pacemakers. Apart from the consideration of adequate informations in literature this evidence above all depends on the evaluation of data of 29 cases from 10 centres for cardiac pacemakers.

[Modification of stimulus threshold increase following heart pacemaker implantation by prednisolone].

In a retrospective study concerning 39 patients with pacemakers is reported on the possibility of a medicamentous influence of so-called increases of the stimulus threshold with exit block. Inflammatory tissue reactions and disturbances of electrolytes as well as microdislocations at the tip of the electrode are given as a cause of the postoperatively appearing deficiency of the stimulation. A differentiation of these causes is not possible with simple paraclinical examination methods. Generally using prednisolone we succeeded in decreasing the stimulus threshold in about half the patients within ca. 3 weeks and thus in removing the exit block. After discussion of the pathophysiological connections recommendations for the therapeutic approach are described.

[Cardiac pacemaker perforation of the transverse colon in the infected pacemaker system].

While perforations of pacemakers outside due to infection or pressure necrosis are no rarity on account of the constantly rising number of patients, perforations into the abdominal cavity are rarely observed. All infectious complications make great demands on the surgical therapy and often demand manifold correction operations. It is reported on the case of a pacemaker perforation into the transverse colon. Our therapeutic principles in infections and perforations of pacemakers are shortly explained.

[Importance of ECG in the monitoring of patients with pacemakers].

As treatment method of choice in permanent bradycardic disturbances of cardiac rhythm the control of pacemaker patients increasingly obtained importance. The knowledge of the normal as well as the disturbed pacemaker ECG is one condition for the optimal care of pacemaker patients, since more and more practicing physicians are involved into this responsible activity. After description of the ECG in intact pacemaker function (including the possibilities of errors) the disturbances most frequently observed in practice (change of the pacemaker frequency, deficits of synchronisation and stimulation) are dealt with and explained.
