Independent of other established risk factors, depressed heart rate variability (HRV) has been shown to be a powerful predictor of cardiac events after MI. Unfortunately, the need of 24-hour ECG recording and subsequent laborious editing of Holter data limits the clinical use of long-term HRV. In order to perform post-MI ...

Because apnea length during periodic breathing varies according to the preceding increase in ventilation and reduction in PaCO 2, differences in the cycle length of periodic breathing among patients with normal and impaired cardiac function might be explained by the influence of lung-to-carotid body circulatory delay, as reflected by lung-to-ear ...

The incidence of neonatal extracorporeal membrane oxygenation (ECMO) is decreasing nationally. This decrease is presumed to be a result of the emergence of alternative technologies such as high-frequency oscillatory ventilation (HFOV), nitric oxide (NO), and surfactant therapy as well as others. The purposes of the present report were to determine ...

In order to evaluate the incidence of cardiac anomalies, type of cardiac defects, and their impact in the Rubinstein-Taybi syndrome (RTS), a questionnaire study was done. Forty-five of 138 patients in the study (32.6%) had a known cardiac abnormality; 27 patients had single defects including atrial septal defect (ASD), ventricular ...

Current knowledge suggests that risks of glucose-containing solutions for patients undergoing CPB are hypothetical at best. Instead, patients may benefit from reduced perioperative fluid requirements bestowed by intraoperative glucose-containing solutions. This risk-benefit analysis does not apply to patients undergoing circulatory arrest. This population endures the certain risk of global CNS ...

To determine the causes of death in autosomal dominant polycystic kidney disease (ADPKD) patients and to examine whether the extrarenal manifestations of ADPKD influence the causes of death, the medical records of 129 patients who died between 1956 and 1993 were reviewed; 58% of the 129 patients had an autopsy ...
Oliveira S A - - 1995
Hypertonic saline-dextran (HSD) solutions have been used for hemorrhagic shock, aortic aneurysm, and cardiopulmonary bypass surgery (CPB). Jehovah's Witness patients refuse blood and derivatives even under life-threatening conditions. A negative fluid balance for Jehovah's Witnesses would avoid further hemodilution. In this study we compared clinical, hemodynamic, laboratory evolution, and fluid ...
Kantor H L - - 1995
The cardiologist and internist can make a major contribution to the care of patients with neurologic disease, both in terms of treating patients with symptomatic cardiac involvement and reducing mortality. This article highlights the need to recognize ECG abnormalities that may represent purely neurologic disease as well as indicate cardiac ...
Yeragani V K - - 1995
Some evidence suggests that patients with panic disorder have a decreased cardiac vagal and a relatively higher sympathetic activity. In this study, spectral analysis of the time series of heart rate before and after isoproterenol infusions was used to study heart rate variability in six panic disorder patients and 11 ...
