Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices

Advanced Materials Technologies, EarlyView.
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

ECG J waves

Journal of Emergencies, Trauma, and Shock, 2008
Osborne waves, also referred to as J waves, were Þ rst described by Tomaszewkski in 1938. The J wave is a positive convex des ection that occurs at the junction of the QRS complex and ST segment, the J-point. They occur most prominently in the inferior leads: II, III, and aVF and the precordial leads: V5–V6 when the core body temperature falls below 32°

ECG Criteria for the Prediction of Infarct-Related Artery and Impact of Coronary Dominance on ECG in Patients with Inferior ST-elevation Myocardial Infarction

Sakarya Tıp Dergisi, 2020
Background In-stent restenosis(ISR) is a common angiographic finding in patients with previous stent implantation. Although the mechanism and predictors of ISR has been well-defined, after definition of neoatherosclerosis, a new perspective was emerged ...

Validity of telemetric-derived measures of heart rate variability: a systematic review [PDF]

, 2016
Heart rate variability (HRV) is a widely accepted indirect measure of autonomic function with widespread application across many settings. Although traditionally measured from the 'gold standard' criterion electrocardiography (ECG), the development of ...

ECG Diagnosis: Hyperkalemia [PDF]

The Permanente Journal, 2013
Diagnosis of hyperkalemia is usually based on laboratory studies, although the electrocardiogram (ECG) may contain changes suggestive of hyperkalemia. Typical ECG findings in hyperkalemia progress from tall, “peaked” T waves and a shortened QT interval to lengthening PR interval and loss of P waves, and then to widening of the QRS complex culminating ...
