Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
Microsoft Access 2007 introduced new file extensions: .accda – Access add-in file.accdb – Access Database.accde – The file extension for Office Access 2007 files that are in "execute only" mode. ACCDE files have all Visual Basic for Applications (VBA) source code hidden. A user of an ACCDE file can only execute VBA code, but not view or ...
Illustration of Implantable Cardioverter Defibrillator (ICD) An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart.
Cardioversion is the attempt to switch an irregular heartbeat to a normal heartbeat using electrical or chemical means. [28] Electrical cardioversion involves the restoration of normal heart rhythm through the application of a DC electrical shock. The exact placement of the pads does not appear to be important.
A phreaking box is a device used by phone phreaks to perform various functions normally reserved for operators and other telephone company employees.. Most phreaking boxes are named after colors, due to folklore surrounding the earliest boxes which suggested that the first ones of each kind were housed in a box or casing of that color.
Beige boxes can be usually constructed with easily available materials, such as a simple "POTS" telephone, a soldering iron, and a pair of alligator clips.Sometimes a switch is added in order to turn the microphone off (mute), so as not to introduce ambient noise into the line through the telephone's microphone.
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
