Since devices portable defibrillator can rapidly produce dramatic improvements in the health of patients, defibrillators are often represented in film, television, video games and other media fantasy. Their function, however, is often exaggerated, with the defibrillator lead to sudden, violent jerk or convulsion by the patient, in fact, although the muscles may contract, which the patient's dramatic presentation Monophasic Defibrillator is rare. Similarly, medical providers are often represented patients with a defibrillation flat-line "ECG rhythm (also known as asystole) this does not happen in real life. Only the rhythms of cardiac arrest and ventricular fibrillation pulseless ventricular tachycardia are normally defibrillated. (There are also several heart rhythms that can be "shocked" when the patient is in cardiac arrest, such as supraventricular tachycardia and ventricular tachycardia that produces a pulse, this procedure is known as cardioversion, defibrillation is not.)

In Australia Lifepack Defibrillator until 1990 was rather uncommon for ambulances to carry defibrillators. The situation changed in 1990 after Australian media mogul Kerry Packer had a heart attack and, coincidentally, the ambulance that responded to the call made a defibrillator. After recovery, Kerry Packer donated a large sum for the Ambulance Service of New South Wales, so all ambulances in New South Wales should have a personal defibrillator, which is why defibrillators are commonly Medtronics defibrillator called in Australia " Packer Whackers "

Resuscitation electrodes are placed according to one of two schemes. The anterior-posterior scheme (confirmable image) is the preferred scheme for the placement of electrodes in the long term. An electrode is placed over the left precordium (the lower chest, facing the heart). The other electrode is placed on the back, behind the heart in the region between the scapula. This position is preferable because it is better for non-invasive stimulation.
The system front-peak can be used when philips heartstart defibrillators the front-back scheme is inconvenient or unnecessary. In this scheme, the front electrode is positioned on the right, under the collarbone. The apex electrode is applied to the patient's left side, just below and left of the pectoral muscle. This scheme works well for defibrillation and cardioversion as well as for monitoring an ECG.
