Bioimpedance 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 کاملCardiac pacing in children
Twenty patients aged between 12 months and 13 years underwent permanent pacemaker implantation. The main indication for pacing was post-surgical atrioventricular block. The complication rate was high and related mainly to infections and lead system problems. The use of small multiprogrammable pacemakers is expected to reduce the reoperation rate for system malfunction and elective replacement. ...
متن کاملCardiac pacing in children.
Advances in pacemaker technology over the last 25 years have made cardiac pacing in infants and children a safe and practical therapy. Some of the technical challenges encountered with the first permanent pacemaker implantation in children during the early 1960s have been solved with miniaturized generators, lithium batteries, noninvasive programmability, and improved placement techniques. This...
متن کاملHemodynamic Effects of Artificial Pacing
The hemodynamic changes associated with complete heart block complicating acute myocardial infarction and the effects of artificial pacing at various rates on these measurements were studied in 13 patients. Studies were performed on the first day of complete block in all patients and were repeated on subsequent days in six. With two exceptions cardiac output was increased by pacing. In patients...
متن کاملApplication of rapid artificial cardiac pacing in thoracic endovascular aortic repair in aged patients
OBJECTIVE To compare the safety, efficacy, and impact on stent graft positioning between rapid artificial cardiac pacing (RACP), induced hypotension and sodium nitroprusside (SNP) induced hypotension during thoracic endovascular aortic repair (TEVAR) for Stanford B aortic dissection. METHODS One hundred and sixty-eight patients, who were diagnosed with Stanford B aortic dissection and who und...
