quential pacing would reduce the risk of heart failure, reduce mortality, and improve quality
of life. Indeed, as dual-chamber pacing was becoming the commonest form of pacing in the …

Surveys of pacing practice have shown a steady increase in pacemaker implantation rates
in the past 15 years, despite no major changes in United States guidelines for permanent …

BACKGROUND: Ninety-nine percent of pacemakers implanted in the United States include
an option for rate modulation. OBJECTIVE: The purpose of this study was to determine …

Introduction: Permanent pacemakers are capable of increasing heart rate in response to
physical activity by a variety of sensors including accelerometers, piezoelectric crystals, or …

Background: The purpose of this study was to describe the incidence and predictors of
sudden cardiac death (SCD) and heart failure (HF) death, and coexisting indications for …

PURPOSE: The study's purpose was to examine body image changes in subjects
participating in a long-term multicenter pacemaker trial. METHODS: At study closeout, 383 …

A rethinking of the physiology of cardiac pacing has led to the concept that although
atrioventricular synchrony supports an improvement in cardiac output and ventricular …

Since the first implantation of a cardiac pacemaker in the second half of the 20th century,
there have been evolutionary and revolutionary advances in the technology developed for …

Pacemaker (PM) therapy has been introduced more than 50 years ago for the treatment of
