Electrical stimulation has been used to prevent muscle atrophy, but this method is different in many previous studies, appropriate stimulation protocol is still not decided. Although resistance exercise has also been shown to be an effective countermeasure on muscle atrophy, almost previous studies carried out an electrical stimulation without resistance. It was hypothesized that electrical sti...

The electrical system of the construction machinery usually works on circumstance of high temperature, serious vibration and shock, dust pollution as well as electromagnetic interference, so the electrical system is very likely to go wrong while compared with other systems, for example working attachment, under chassis and so on. In view of this, an advanced fault test device, with application ...

An electrical storm is a fearful and life threatening experience for the patient while it is a therapeutic challenge of the extreme degree for the physician. In this issue of the Journal, Proietti and Sagone have presented an in depth discussion on the various aspects of the electrical storm including the current day management [1]. As rightly mentioned by them, the present definition of an ele...

Introduction A high-voltage (HV) electrical short circuit can be a critical electrical failure in an implantable cardioverter-defibrillator (ICD) system because of the failed delivery of appropriate shocks against fatal arrhythmia. The Food and Drug Administration has classified the St Jude Medical Riata family of ICD leads (St Jude Medical, St Paul, MN) as a class I recall since 2011 because o...

Currently there are limitations in computing chatter behavior of small electrical contacts embedded in components using finite element models. Reduced order models (ROM) have been developed of such electrical contact sub-assemblies to assess the chatter behavior of the contacts during vibration and shock environments. The current ROM method requires experimental validation. This ROM also neglec...

Myocardial infarction is one potential outcome after an electric shock though it is seen relatively rarely. Nonetheless, an increased death rate because of cardiopulmonary arrest is of concern and merits careful scrutiny. Here, we report a man with myocardial infarction following electrical shock. Although he had frankly normal coronary arteries by coronary angiography, myocardial infarction wa...

Fabrizio Vianello, Fourth Chair of Medicine, Department of Semeiotics, University of Padua, I-35100 Padua (Italy) Dear Sir, Myocardial injuries represent a common feature of electric shock. Cardiovascular effects of electrical injury include immediate cardiac arrest, acute myocardial necrosis, myocardial ischemia without necrosis, dys-rhythmias, hemorrhagic pericarditis, acute hypertension with...

BACKGROUND It is currently believed that defibrillation shocks act primarily by stimulating excitable myocardium to abolish wave fronts. Recent studies have shown that shocks applied during pacing not only stimulate excitable myocardium but also prolong the depolarization and refractoriness of myocardium already in a depolarized state. This study investigates the effects of shocks on fibrillati...
