Rate-modulated pacing.
The primary role of cardiac rate in adapting cardiac output to changing physiological needs has been more clearly recognized in recent years. Previously, the rate of cardiac stimulation had been determined either at pacemaker manufacture, by programming a single rate, or by sensing the atrium. More recently, sensing another physiological or nonphysiological function that changes in response to ...
متن کاملCurrent status of cardiac rehabilitation.
Cardiac rehabilitation is increasingly recognized as an integral component of the continuum of care for patients with cardiovascular disease. Its application is a class I recommendation in most contemporary cardiovascular clinical practice guidelines. Despite the documentation of substantial morbidity and mortality benefits, cardiac rehabilitation services are vastly underutilized. The core com...
متن کاملThe incremental benefit of rate-adaptive pacing on exercise performance during cardiac resynchronization therapy.
OBJECTIVES The purpose of this research was to investigate the effect of using rate-adaptive pacing and atrioventricular interval (AVI) adaptation on exercise performance during cardiac resynchronization therapy (CRT). BACKGROUND The potential incremental benefits of using rate-adaptive pacing and AVI adaptation with CRT during exercise have not been studied. METHODS We studied 20 patients ...
متن کاملRespiration as a reliable physiological sensor for controlling cardiac pacing rate.
A study was carried out to determine whether variations in the respiration rate during physical exercise could be used as a physiological variable in controlling the rate of an implanted pacemaker. The relation between respiration rate and heart rate was significantly correlated in 73 patients (19 with normal lung function, four with restrictive pulmonary disease, and 50 with obstructive airway...
متن کاملLeft univentricular pacing for cardiac resynchronization therapy using rate-adaptive atrioventricular delay
OBJECTIVE To evaluate left univentricular (LUV) pacing for cardiac resynchronization therapy (CRT) using a rate-adaptive atrioventricular delay (RAAVD) algorithm to track physiological atrioventricular delay (AVD). METHODS A total of 72 patients with congestive heart failure (CHF) were randomized to RAAVD LUV pacing versus standard biventricular (BiV) pacing in a 1: 1 ratio. Echocardiography ...
