Closed Loop Stimulation and Evaluation of the Effect of the Autonomic Nervous System Using Heart Rate Variability
Rate-Responsive Pacemakers Rate-responsive pacemakers are widely used to treat chronotropic incompetence as well as complete atrioventricular (AV) block or sinus node disease. Of the several sensor concepts that have been evaluated since 1980, the activity sensor (accelerometer) and two physiologic models (minute ventilation and QT interval) have been predominantly used in clinical practice. So...
متن کاملChronotropic incompetence: a never-ending story.
A clear association between chronotropic incompetence and increased mortality has been established by a variety of studies in patients with coronary artery disease as well as in healthy individuals. These results gave rise to speculation that rate responsive stimulation might improve prognosis in pacemaker (PM) patients with concomitant chronotropic incompetence. To date, however, no study was ...
متن کاملCan chronotropic incompetence predict life-threatening ventricular arrhythmias in patients with stable ischemic heart disease?
Background: Chronotropic incompetence has prognostic value of all-cause and cardiovascular mortality in both patients with asymptomatic and symptomatic ischemic heart disease (IHD), regardless of traditional risk factors. The aim of this study was to investigate the relationship between chronotropic response during exercise test and the development of ventricular arrhythmias. Methods: 153 pati...
متن کاملChronic heart failure, chronotropic incompetence, and the effects of beta blockade.
OBJECTIVE To establish the prevalence of chronotropic incompetence in a cohort of patients with chronic heart failure (CHF) taking modern medications for heart failure, and whether this affected exercise capacity and predicted prognosis. METHODS Heart rate response to exercise was examined in 237 patients with CHF in sinus rhythm, who were compared with 118 control volunteers. The percentage ...
متن کاملA Closed-loop quantitative verification of rate-adaptive pacemakers
Rate-adaptive pacemakers are cardiac devices able to automatically adjust the pacing rate in patients with chronotropic incompetence, i.e. whose heart is unable to provide an adequate rate at increasing levels of physical, mental or emotional activity. These devices work by processing data from physiological sensors in order to detect the patient’s activity and update the pacing rate accordingl...
