Measurement of Tip Load With a Pacemaker Lead Stylet and Guiding Catheter Using a Silicone Heart Model.

Cardiology, Akita Cerebrospinal and Cardiovascular Center, Akita, JPN.
Background Ventricular septal pacing has long been performed using a stylet during pacemaker implantation, but with the availability of guiding catheters, His bundle pacing and left bundle branch area pacing have also been performed. However, it is not known to what extent the tip load of the ventricular lead differs when a guiding catheter is used compared with a stylet alone. In this study, the tip load was measured for different stylet stiffness and guiding catheter geometries at sites where His bundle pacing and left bundle branch area pacing were assumed.

Background: Patients with acute and high-risk pulmonary embolism have a high mortality rate, and the optimal treatment for these patients has still not been fully established. Although anticoagulation therapy is currently the preferred treatment for pulmonary embolism, for some patients with intermediate- or high-risk pulmonary embolism, anticoagulation therapy alone has a higher probability of long-term pulmonary hypertension and also seriously worsens the quality of life of patients. This paper mainly reports the efficacy and safety of percutaneous mechanical thrombectomy (PMT) in patients with acute medium- or high-risk pulmonary embolism in Taizhou Hospital of Zhejiang Province so as to provide some clinical basis for the treatment of such patients in the future.

Introduction: Health care-associated infections (HAIs) contribute to morbidity and mortality and to the dissemination of multidrug-resistant organisms. Children admitted to the intensive care unit undergo invasive procedures that increase their risk of developing HAIs and sepsis. The aim of the study was to analyse factors associated with mortality due to sepsis arising from HAIs.

Phasic cardiac vagal activity (CVA), reflecting ongoing, moment-to-moment psychophysiological adaptations to environmental changes, can serve as a predictor of individual difference in executive function, particularly executive performance. However, the relationship between phasic CVA and executive function demands requires further validation because of previous inconsistent findings. Moreover, it remains unclear what types of phasic changes of CVA may be adaptive in response to heightened executive demands.
