Background: The R wave in lead aVR, during the wide QRS complex tachycardia, is commonly observed in a ventricular tachycardia (VT) arising from certain locations in the ventricles.
Objectives: This was a retrospective and a proof of concept study to correlate the sites of origin of VT and premature ventricular contractions (PVCs) with the occurrence of R wave in lead aVR.
Methods: Patients with VT or high density of PVCs were included.
Retrospective case studies are one approach to help identify processes underlying the translation of successful health interventions. This case study investigates the development of and (), decision support tools for breast cancer risk assessment, and risk-stratified prevention. Following a recently developed protocol for retrospective translational science case studies, we examined the career trajectory of Dr Katherine Crew as she expanded from basic science to interdisciplinary, patient-oriented research in oncology and began collaboration with Dr Rita Kukafka, a public health informatician focused on communicating risk.

However, no study yet has evaluated this simultaneous symptom-rhythm correlation in patients with heart failure (HF). We aimed to measure the correlation between symptoms and atrial arrhythmia (ATAF) episodes among patients with HF and known AF using prolonged AECG monitoring.

- Management of atrial fibrillation (AF) often focuses on alleviating symptoms, but the relationship between these symptoms and heart rhythm disturbances (like atrial tachycardia/AF) is not well understood when monitored using ambulatory electrocardiography (AECG).
- A study analyzed AECG data from 742 patients, revealing a low symptom-rhythm correlation (SRC) of 0.39, indicating that while AT/AF events significantly increase the likelihood of symptoms, many episodes do not correspond well with reported symptoms.
- Factors such as previous treatment for AF and lower heart rates were found to negatively impact SRC, highlighting the need for more in-depth research to better link symptoms and heart rhythms for improved patient care.
Introduction: Low-frequency, low-intensity ultrasound has been previously shown to promote healing of chronic wounds in humans, but mechanisms behind these effects are poorly understood. The purpose of this study was to evaluate gene expression differences in debrided human venous ulcer tissue from patients treated with low-frequency (20 kHz), low-intensity (100 mW/cm) ultrasound compared to a sham treatment in an effort to better understand the potential biological mechanisms.
Methods: Debrided venous ulcer tissue was collected from 32 subjects one week after sham treatment or low-frequency, low-intensity ultrasound treatment.
