This paper introduces a new method which controls discharge energy accurately. It is achieved by calculating target voltage based on transthoracic impedance and accurately controlling charging voltage and discharge pulse width. A new defibrillator is designed and programmed using this method. The test results show that this method is valid and applicable to all kinds of external defibrillators.

Electric accidents that are increasing can damage myocardium, lead to reduce contraction of myocardium, ventricular fibrillation, non-systole, and eventually cardiac arrest. Study on 35 patients with cardiac and breathing arrest since 1995-1997 shown that the youngest people were died when they contacted with low voltage due to arrhythmia. The first aid is very important, artificial respiration, cardiac massage, it shouldn't transfer to hospital when they have cardiac and breathing arrest. First dose of electric shock: 200J, second time: 3000J, and from third time: 4000J. It should use electric safe devices.

Using beta-blocker propranolone immediately after electric shock helped successful treatment in 2 female patients, 21 years old and 27 years old, who experienced schizophrenia (F20) and had treated by antidepressant drugs. After treatment, both of them were stable and only used drugs at median dose. After electric shock they ate and slept well, had stable behaviour, and pulse was 80-90 c/m. Patients discharged after 1 week

Cardiac rhythm management device (CRMD) infection is rare, but potentially life-threatening complication. Despite technical evolution of cardiac device, the cases of CRMD infection have increased remarkably over the past decades. In this review, several important key points were discussed with regards to the epidemiology, pathogenesis, risk factors, microbiology, clinical manifestations, diagnosis, treatment and prevention of CRMD infection.

We present an unusual case of a delayed right ventricular perforation by a single standard-caliber implantable cardioverter-defibrillator lead, which manifested 14 days after implantation. Multidetector computed tomography could clearly display the lead perforation, and allow for identification of the associated sequelae such as pericardial effusion and planning the lead extraction strategy.
