Sinusoidal heart rate rhythms in severe neonatal hypoxia.
Sinusoidal heart rate traces were detected in 8 patients, 6 of whom died; the 2 survivors showed evidence of gross cerebral damage. It is felt that the origin of the sinusoidal curve is probably central and reflects loss of central control of heart rate.
متن کاملImpact of acute hypoxia on heart rate and blood pressure variability in conscious dogs.
To examine whether the impacts of hypoxia on autonomic regulations involve the phasic modulations as well as tonic controls of cardiovascular variables, heart rate, blood pressure, and their variability during isocapnic progressive hypoxia were analyzed in trained conscious dogs prepared with a permanent tracheostomy and an implanted blood pressure telemetry unit. Data were obtained at baseline...
متن کاملBenefit of Heart Rate Reduction in Heart Failure
Epidemiological studies have suggested that life expectancy is inversely related to resting heart rate and that the risks of development of heart failure and sudden cardiac death strongly increase with higher resting heart rates [1]. After myocardial infarction, the reduction in mortality with β-blocker treatment was correlated with the extent of heart rate reduction, and in patients with heart...
متن کاملevaluation of maximum o2 consumption: using ergo-spirometry in severe heart failure
although sport-physiologists have repeatedly analyzed respiratory gases through exercise, it is relatively new in the cardiovascular field and is obviously more acceptable than standard exercise test, which gives only information about the existence or absence of cardiovascular diseases (cvds). through the new method of exercise test, parameters including aerobic and anaerobic are checked and m...
متن کاملCheckmark fetal heart rate pattern associated with severe fetal hypoxia. A case report.
A 31-year-old nulliparous woman developed vaginal bleeding after spontaneous rupture of the membranes at 40 weeks of gestation. Fetal heart rate monitoring showed checkmark and sinusoidal patterns. A 3,281 g male neonate was delivered by emergency cesarean section, with Apgar scores of 1 and 3 at 1 and 5 min, respectively. The neonate exhibited severe acidosis with arterial blood gas pH of 6.96...
