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 ...

Objective: Observe and correlate the funneling of upper cervical canal by ultrasound likelihood incompetence premature delivery in twin pregnancy. Materials methods: Retrospective study pregnancies deliveries 1997, king Faisal specialist hospital research center, Riyadh, Saudi Arabia. A total 67 underwent routine for fetal assessment, when cervix closed, long; short, funneling. The time was div...

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 ...

CONTEXT Checklists are commonly used in the assessment of procedural competence. However, on most checklists, high scores are often unable to rule out incompetence as the commission of a few serious procedural errors typically results in only a minimal reduction in performance score. We hypothesised that checklists constructed based on procedural errors may be better at identifying incompetence...

M EIER and Zierlerl have lucidly presented the theory underlying the application of indicator dilution of the measurement of flow in the vascular bed. This theory is not violated by the presence of valve incompetence provided that indicator particles that recirculate and reenter the vascular system can be excluded from the primary indicator concentration-time curve. Valve incompetence results i...
