Assessment of endocardial leads for permanent cardiac pacing.
Catheter tip dislocation is the main complication of permanent pacemaker implantation using the subclavian vein. In this study of 50 patients we compared the incidence of complications using two endocardial electrodes specially designed to prevent tip dislocation. One catheter had a helical endocardial electrode and the other had retractable nylon barbs. The helical electrode was superior in ev...
متن کاملBioimpedance Based Control of Rate Limits in Artificial Cardiac Pacing
The unhealthy heart can not operate at both, significantly high and low rates because of reducing of the myocardium’s energy supply E (in comparison with energy consumption for work W), which is proportional to the blood inflow equal to ∆P/R, where ∆P is the blood pressure difference, and R is the hydraulic resistance of the vascular system of the heart itself (Fig.1). The limits between which ...
متن کاملProlonged temporary cardiac pacing using subcutaneous tunnelled active-fixation permanent pacing leads.
Temporary transvenous cardiac pacing is occasionally required for prolonged periods, particularly in patients with severe infection and bradyarrhythmias who may need several weeks of antibiotic treatment before a permanent pacemaker can be safely implanted. Prolonged temporary transvenous pacing is frequently associated with complications such as local or systemic infection, lead displacement, ...
متن کاملUse of artificial intelligence in cardiac imaging.
There has been a trend over the past few decades toward increasing use of quantitation in cardiac perfusion imaging , initially for planar imaging (1–3) and subsequently for SPECT imaging (4–8). Such quantitation may assist the novice reader, thereby increasing the accuracy of the interpretation. Even in the setting of relatively expert readers, quan-titation provides the opinion of a second ex...
متن کاملUse of subclavian vein for permanent cardiac pacing.
The subclavian vein has been used to implant permanent pacing catheters in 40 patients with symptomatic heart block. Though the cephalic and external jugular veins are usually preferred for this purpose in Britain, the use of these veins has certain disadvantages. In this study subclavian venepuncture by the infraclavicular approach was performed without diffculty and found to be a safe procedu...
