Defibrillator1
Onset The sooner an electrical countershock from a defibrillator can be given after the start of VF, then the greater the certainty of rich defibrillation. (kazanpress.ru)
Shock5
During a cardioversion, an electrical shock is given to your heart. (nshealth.ca)
Myocardial scintigrams are helpful in determining the degree of damage produced by penetrating wounds of the heart and can also detect electrical injury to the heart from accidental shock or cardioversion. (elsevierpure.com)
A halted heart can be restarted with an electric shock (often referred to as a counter-shock), or a chaotic rhythm can be momentarily interrupted. (creativesmags.com)
They were surgically positioned and deliver pacing - or an electric powered counter-shock - to the center when a life-threatening abnormal beat is what is dabble actually found. (bayareabalanceddogtraining.com)

Cardioversion4
In the presence of reentrant-induced arrhythmia, such as paroxysmal supraventricular tachycardia (PSVT) and ventricular tachycardia (VT), electrical cardioversion interrupts the self-perpetuating circuit and restores a sinus rhythm. (medscape.com)
Electrical cardioversion is much less effective in treating arrhythmia caused by increased automaticity (eg, digitalis-induced tachycardia, catecholamine-induced arrhythmia) since the mechanism of the arrhythmia remains after the arrhythmia is terminated and therefore is likely to recur. (medscape.com)
150) who is unstable (eg, chest pain, pulmonary edema, lightheadedness, hypotension) should be immediately treated with synchronized electrical cardioversion. (medscape.com)
Synchronized electrical cardioversion may also be used to treat stable VT that does not respond to a trial of intravenous medications. (medscape.com)
Shocks4
He accomplished these feats with the application of indirect and direct electrical shocks that restored a life sustaining heart rhythm. (wikipedia.org)
Paul Zoll developed methods of applying electric shocks to the surface of the chest that stimulated the heart within. (wikipedia.org)
The device weighed 28 pounds and used an oral/epigastric and a precordial electrode to record ECG tracings and deliver electrical shocks. (medscape.com)
Selye later confirmed that when rats are exposed to adverse conditions such an electric shocks, cold and surgical procedures the same reactions took place. (nmmra.org)
Stimulation3
After showing for the first time that electrical stimulation can revive a heart that has stopped beating, he went on to conduct research that led to the creation of the first pacemaker in 1952. (encyclopedia.com)
