Osborn Waves: History and Significance [PDF]

open access: yes, 2004
The Osborn wave is a deflection with a dome or hump configuration occurring at the R-ST junction (J point) on the ECG (Fig. 1). In the historical view, different names have been used for this wave in the medical literature, such as “camel-hump sign ...

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management

open access: yesAdvanced Science, EarlyView.
Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

The effects of inhomogeneities on scroll-wave dynamics in an anatomically realistic mathematical model for canine ventricular tissue [PDF]

open access: yesarXiv, 2020
Ventricular tachycardia (VT) and ventricular fibrillation (VF) are lethal rhythm disorders, which are associated with the occurrence of abnormal electrical scroll waves in the heart. Given the technical limitations of imaging and probing, the in situ visualization of these waves inside cardiac tissue remains a challenge.

Left atrial appendage thrombosis in a patient with Friedreich Ataxia–related cardiomyopathy, left ventricular systolic dysfunction, and atrial fibrillation

open access: yesSAGE Open Medical Case Reports, 2021
Friedreich ataxia is the most common form of hereditary ataxia. Heart involvement in Friedreich ataxia is common and can include increased left ventricular wall thickness, atrial fibrillation, and in the later stages, a reduction of left ventricular ...

Electrical Storms in Brugada Syndrome: Review of Pharmacologic and Ablative Therapeutic Options [PDF]

open access: yes, 2005
Electrical storm occurring in a patient with the Brugada syndrome is an exceptional but malignant and potentially lethal event. Efficient therapeutic solutions should be known and urgently applied because of the inability of usual antiarrhythmic means in

Atrial Fibrillation Degenerates Into Ventricular Fibrillation

open access: yesJournal of the American College of Cardiology, 2010
![Figure][1] A 43-year-old man with paroxysmal atrial fibrillation (AF) and an implantable cardioverter defibrillator (ICD) placed for documented ventricular fibrillation (VF), presented with an ICD shock. Ventricular pre-excitation was not present.

Spontaneous termination of ventricular fibrillation [PDF]

open access: yesHeart, 2004
A 65 year old woman with hypertension and permanent atrial fibrillation had suffered two brief syncopal episodes. She was on losartan, digoxin, and aspirin. The ECG showed atrial fibrillation and incomplete left bundle branch block; the QT interval was 0.36 s and the QTc 0.414 s. The echocardiogram revealed mild dilatation and dysfunction of …

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

open access: yesAdvanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.
