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 ...
If the fast heart rate is poorly tolerated (e.g. the development of heart failure symptoms, low blood pressure or coma) then AVNRT can be terminated electrically using a cardioversion. In this procedure, after administering a strong sedative or general anaesthetic, an electric shock is applied to the heart to restore a normal rhythm. [8]
Myocardial stunning or transient post-ischemic myocardial dysfunction is a state of mechanical cardiac dysfunction that can occur in a portion of myocardium without necrosis after a brief interruption in perfusion, despite the timely restoration of normal coronary blood flow.
Cardioversion is either achieved pharmacologically or via the application of a shock synchronized to the underlying heartbeat. It is used for the treatment of supraventricular tachycardias. In elective cardioversion, the recipient is usually sedated or lightly anesthetized for the procedure. Defibrillation differs in that the shock is not ...
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.
Of course, if you're feeling sick, it’s a good idea to test yourself so you can know the full picture of what you’re dealing with, says Thomas Russo, MD, a professor and chief of infectious ...
It is only when bradycardia presents with signs and symptoms of shock that it requires emergency treatment with transcutaneous pacing. False capture with visible phantom beats [ 3 ] Some common causes of hemodynamically significant bradycardia include myocardial infarction , sinus node dysfunction and complete heart block .
2. Excessive Stress. Stress is a natural, normal part of the human experience, and your body knows how to handle it. When you’re under stress, your body releases stress hormones that activate ...
