Rapid wide QRS tachycardia with an unknown cause
Annals of Noninvasive Electrocardiology, 2022 One‐to‐one atrioventricular conduction during atrial flutter is one of the most severe life‐threatening arrhythmias and is hemodynamically perilous. Rapid wide QRS tachycardia often not only occurs in patients with ventricular tachycardia but is also ...

State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide
Advanced Photonics Research, EarlyView.State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...
