Abstract

The dislodgement rate of endocardially placed pacemaker leads can be decreased by the use of special-type electrodes. Since 1963 a total of 2100 pacemaker implantations was performed. Since 1970 we have been using special-type electrodes in 15 to 20% of our patients each year. The complication rate of all pacemaker leads implanted in the period 1974 to 1978 was 7.6%, the rate of the special type electrodes alone came up to 15%. The lead IE--65--I had the greatest deal of this - 11 out of 43 leads had to be removed. 152 electrodes type IVE--85--armed with metal hooks - were implanted, 18 of which had to be revised and 17 of 117 rigid leads type IE--60--KS--10 revealed failure which made revision necessary. In contrast, 54 screw-in leads type 6957, Medtronik and AE--60--YR, Biotronik caused only one perforation - a lethal one. Primary experiences with a porous tip lead (CPII--4116) are good enough to recommend the use of this electrode as a lead of first choice. We saw 2 dislodgements in 50 implantations. Failure to sense or to pace were never seen (time of observation 2 to 18 months).

Safety of nerve conduction studies in patients with implanted cardiac devices.

Patients with implanted cardiac devices and their physicians may defer important electrodiagnostic testing because of anxiety about potential negative effects on the device. To determine the safety of routine nerve conduction studies (NCS) in this population, 10 patients with permanent dual-chamber pacemakers of various types and five patients with implanted cardiac defibrillators (ICD) underwent nerve stimulation at sites commonly used during NCS. The implanted cardiac device was interrogated before and after the study and there was continuous monitoring of the surface electrocardiogram (ECG) and atrial and ventricular electrograms. Electrical impulses generated during routine NCS were never detected by the sensing amplifier and did not affect the programmed settings of the implanted cardiac device. We conclude that routine NCS is safe in patients with implanted cardiac pacemakers with bipolar sensing configurations and defibrillators.

[Pulmonary diseases and heart function].

The most severe cardiac sequel to lung disease is the load on the right ventricle due to pulmonary hypertension with the development of a cor pulmonale. This is characterized by hypertrophy and/or dilatation of the right ventricle because of a primary impairment of lung function and/or lung structure. The most important pathomechanisms for the development of pulmonary hypertension are vessel obliteration, mechanical lesions, primary vascular or extra-vascular inflammation and hypoxic vasoconstriction. Chronic obstructive pulmonary disease (COPD) is one of the most important reasons for chronic cor pulmonale. A further very common reason is obstructive sleep apnea syndrome, especially if combined with a COPD. In this case, the prevalence of cor pulmonale can reach 80%. The development of a chronic cor pulmonale is the most striking negative prognostic factor for these patients. Only 30% of COPD patients with cor pulmonale survive longer than 5 years, and only early detection of the disturbances to respiration which might potentially lead to cor pulmonale and their subsequent therapy are able to improve the patient's prognosis. Furthermore, pulmonary diseases may also have an impact on the left heart side in terms of an impairment of left heart function or by inducing severe arrhythmias . Thus, lung diseases may have both a significant impact on right and left heart performance.
