►Implication for health policy/practice/research/medical education: This report demonstrates new criteria for patient selection in CRT era. We started diagnosing Bundle Branch Block about 100 years ago on dog models (1). However, about 40 years passed until we could diagnose Left Bundle Branch Block (LBBB) correctly on ECG (2). Today, we have conventional criteria for diagnosing LBBB, including...

Obligately biotrophic plant pathogens pose challenges in population genetic studies due to their genomic complexities and elaborate culturing requirements with limited biomass. Hop powdery mildew (Podosphaera macularis) is an obligately ascomycete that threatens sustainable hop production. P. macularis populations of the Pacific Northwest (PNW) United States differ from those Midwest Northeaste...

The article presents a case report of the Chatterjee phenomenon after implantation pacemaker in patient with heart failure preserved ejection fraction. During hospitalization specialized cardiology hospital, patient's electrocardiogram (ECG) showed atrial fibrillation (AF) ventricular rate 49 bpm, ST segment depression 1 mm I, II, V4-V6 leads. Taking into account data 24-hour ECG monitoring (pa...

Abstract Funding Acknowledgements Type of funding sources: None. Background Left bundle branch (LBB) area pacing (LBBAP) has been widely adopted for an increasing number antibradycardia and CRT procedures worldwide. Two different types capture have described during LBBAP: left ventricular septal myocardial (LVSP) or direct LBB (LBBP). Nevertheless, electrocardiographic diagnosis LBBAP remains o...

BACKGROUND The goals of this study were to compare ECG at moderate exercise in normoxia and hypoxia at the same heart rate, to provide evidence of independent predictors of hypoxia-induced ECG changes, and to evaluate ECG risk factors of severe high-altitude illness. METHODS AND RESULTS A total of 456 subjects performed a 20-minute hypoxia exercise test with continuous recording of ECG and ph...
