Acute heart failure is a cardiovascular emergency that requires urgent and appropriate treatment. In which the treatment of acute heart failure has not improved with drugs, there are many new effective treatment methods for patients.

Acute heart failure including acute pulmonary edema or cardiogenic shock is a pathology in cardiovascular resuscitation. Acute heart failure usually has a primary onset of decompensated acute heart failure on the background of chronic heart failure. Diagnosis and management of acute heart failure should be carried out urgently and effectively. If not treated promptly, the patient can die quickly.

Atrial fibrillation is the result of chaotic electrical signals in the upper heart chambers (atria). Atrial fibrillation causes an irregular and fast heartbeat. Treatment of atrial fibrillation needs to be methodical and timely.

Electric shock is a treatment method that helps to quickly extinguish and stabilize cardiac arrhythmias. There are two methods of electric shock being used, including: cardioversion and defibrillation.

External cardioversion uses high-energy direct current (DC) energy delivered in a very short period of time to simultaneously depolarize most of the heart muscle cells to restore a normal heart rhythm.

Electric cardioversion is a method of using electric current to suppress rapid arrhythmias that are taking over the sinus rhythm, allowing the sinus rhythm to return to its role as the pacemaker. It should be noted that electric shock should not be understood as using electric current to "stimulate" the heart to beat.

Indications for treatment of arrhythmias with extrathoracic electric shock will depend on the symptoms and severity of the patient. In some cases, it is possible to combine methods for cardiovascular emergency such as: medication, defibrillation, cardioversion, implantation of pacemaker - automatic defibrillator (ICDs), resynchronized pacemaker heart, pacemaker implantation, and surgery.
