GLOSSARY
Sudden Cardiac Arrest (SCA)
Sudden cardiac arrest is a condition in which the heart suddenly stops pumping efficiently
due to an electrical malfunction of the heart. Often, the victims of SCA do not present
premonitory signals or symptoms. SCA can also occur in individuals with previously
diagnosed cardiac conditions. The survival of SCA victims depends on the immediacy of
cardiopulmonary resuscitation (CPR). The use of an external defibrillator within the first
minutes of collapsing can considerably increase the patient's possibility of survival. Heart
attack and SCA are not the same thing, although a heart attack can lead to SCA. If the
symptoms of a heart attack develop (pain, pressure, shortness of breath, sensation of
compression on the chest or other parts of the body), seek immediate emergency medical
attention.
Heartbeat
The normal electric rhythm of cardiac muscle contraction to create blood flow throughout
the entire body is known as Sinus Rhythm. Ventricular fibrillation (VF) caused by chaotic
electrical signals in the heart is often caused by SCA, but a shock can be administered to
re-establish sinus rhythm. The treatment is called defibrillation. The AED is designed to
automatically detect ventricular fibrillation (VF) and perform defibrillation on the victims of
sudden cardiac arrest.
Ventricular Tachycardia / Ventricular Fibrillation
This is a potentially lethal heartbeat which can be cured through AED treatment.
Sinus Rhythm
Sinus Rhythm is the normal electric rhythm of cardiac muscle contraction and expansion
to create blood flow throughout the entire body.
Biphasic Shock
Biphasic shock is an electrical current that travels through the heart, first in one direction,
then the other.
Biphasic Truncated Exponential (BTE) waveform
The Biphasic Truncated Exponential (BTE) waveform stands for Self Compensating
Output Pulse Envelope.
Pad
The pads are the electrodes that are applied to the patient's chest in order to administer
the therapy.
Electromagnetic Interference
Electromagnetic interference is radio interference that could cause defective operation of
the electronic devices.
Impedance Measurement
Impedance measurement is a control that is carried out to check the integrity of the
contact between AED and patient.
