The recommendations for electrical therapies described in this section are designed to improve survival from SCA and life-threatening arrhythmias. Whenever defibrillation is attempted, rescuers must coordinate high-quality CPR with defibrillation to minimize interruptions in chest compressions and to ensure immediate resumption of chest compressions after shock delivery. The high first-shock ef...

This paper deals with the development of a model for concrete subjected to dynamic loads. Shock waves are generated by Pulsed Arc Electro-hydraulic Discharges (PAED) in water and applied to mortar samples. A diphasic model (liquid water and vapour) is implemented in order to describe the electrical discharge and the propagation of shock waves in water. An anisotropic damage model is devised, wh...

The application in this hospital of alternating current for electro-convulsive therapy (E.C.T.) and electronarcbsis in certain mental disturhances afforded the opportunity of investigating the effects of this form of therapy on some of the components of the hlood. Schiitz (1942) ohserved in vitro a delayed coagulation of blood following application of a weak direct current. Brecht and Kummer (1...

Transthoracic synchronized direct current discharge or cardioversion was introduced nearly 25 years ago to restore sinus rhythm in patients with diverse tachyarrhythmias (I). This simple, expeditious and nearly complication-freemethod has withstood the test of time. The likelihood of serious adverse reactions is related more to the underlying mechanism being treated than to the electrical disch...

How does the affective significance of emotional faces affect perceptual decisions? We manipulated affective significance by pairing 100% fearful faces with aversive electrical stimulation and hypothesized that increasing the significance of a stimulus via its prior history would lead to enhanced processing. After fear conditioning, participants viewed graded emotional faces that ranged from ne...

The murine vibrissae sensorimotor system has been scrutinized as a target of motor learning through trace classical conditioning. Conditioned eyelid responses were acquired by using weak electrical whisker-pad stimulation as conditioned stimulus (CS) and strong electrical periorbital stimulation as unconditioned stimulus (US). In addition, conditioned vibrissal protraction was obtained pairing ...

TENS (Transcutaneous Electrical Nerve Stimulator) is a therapeutic device used to deliver electric current through one’s skin. As the device is used on the human body, safety concern becomes a matter that needs special attention. One option for electrical safety is testing whether the electrode has attached properly to the skin. The test is done in the interval of the simulator pulse. This opti...

current into your system may seem distressing. However, the use of electrical shock is commonly used to treat patients experiencing heart conditions such as cardiac arrest. Recently, external electrical stimulation has been substituted for gym time and is used to produce "fake" stimulation of the nerves surrounding muscles. This often produces the same effects that may result from an (honest) h...

Investigations of injuries and fires caused by electrical circuits and equipment can result in incorrect conclusions when grounding systems are neglected. The term ground is loosely used in electrical jargon as any zero reference point for voltage measurement. Power systems are usually grounded to the earth. Other electrical systems are sometimes grounded to the same earth through a low impedan...
