[The French pacemaker register].

The European ID card is the basis for the national registers of pacemaker wearers. The French register, dating from 1986, currently groups 2/3 of implantations or replacements performed each year in France. Year to year comparisons allow measurement of the indications for implanting and the equipment implanted, pacemakers as well as electrode probes. This allows an epidemiological approach which is particularly important since the advent of new equipment and new techniques such as multisite pacing. Within the framework of equipment surveillance and pacing surveillance, the French register could also lead to an important role.

[Thrombophlebitis on intravenous cardiac stimulator electrodes].

The main feature of venous thrombosis on endocardial pacing electrodes are described with reference to 7 cases: the incidence is relatively low (0.4 to 4 p. 100) and the diagnosis obvious in the typical axillary-subclavian form associated with pain, oedema and collateral circulation. Diagnosis is mainly clinical and rehoplethysmography, rather than venography with its potential complications, is the complementary investigation of choice. Internal jugular, innominate vein, vena cava and intracardiac thrombosis may also occur. The vena cava syndromes are observed mainly in patients with multiple electrodes. Atrial or ventricular endocavitary thrombosis may give rise to hemodynamic signs of cardiac failure or to thromboembolism which may be fatal. Operational technique is an important factor in the etiology of early thrombosis especially when the approach vein is ligatured. In the late period, the loss of venous mobility due to the presence of a foreign body makes the vessel susceptible to compression in the cervico-brachial region. The mainstay of treatment is anticoagulation with intravenous or subcutaneous heparin with mobilisation and elevation of the affected arm. Fibrinolysis may be indicated in superior vena cava syndromes (case no 1), the results being better when therapy is instituted early on. Long term anticoagulation is not indicated (case no 7) and may even be dangerous in elderly patients with multiple electrodes.

[Effects of intravenous electrodes of cardiac pacemakers. Clinical and plethysmographic approach].

The authors study the haemodynamics of the endovenous electrodes of cardiac stimulators (EE) in the light of clinical and plethysmographic investigations. Seven venous thromboses were observed out of 2,000 implantations of stimulators (0.35%). The risk increases with age 7th decade) and the presence of multiple EEs. The comparative plethysmography of a series of 22 normal young subjects and 28 old patients equipped with EEs demonstrates that the deep venous return in the upper limbs of a normal subject is better in a young person and in a dominant limb. In the subject equipped with an EE, distensibility is reduced. Temporary coagulation has its place in the treatment of these phlebites (heparin, followed by calciparin). Surgery to disobstruct or excise EE or fibrinolytics are only required exceptionally.
