GLOSSARY
Sudden Cardiac Arrest (SCA)
Sudden cardiac arrest is a condition in which the heart suddenly stops pumping effectively
due to a malfunction of the heart's electrical system. Often victims of SCA have no prior
warning signs or symptoms. SCA can also occur in people with previously diagnosed
heart conditions. Survival for an SCA victim depends on immediate cardio-pulmonary
resuscitation (CPR). The use of an external defibrillator within the first few minutes of
collapse can greatly improve the patients' chances of survival. Heart attack and SCA are
not the same, though sometimes a heart attack can lead to a SCA. If you are experiencing
symptoms of a heart attack (pain, pressure, shortness of breath, squeezing feeling in
chest or elsewhere in the body) seek emergency medical attention immediately.
Heart Rhythm
The normal electrical rhythm by which the heart muscle contracts to create blood flow
around the body is known as Sinus Rhythm. Ventricular Fibrillation (VF) caused by
chaotic electrical signals in the heart is often the cause of SCA, but a shock can be
administered to re-establish sinus rhythm. This treatment is called defibrillation. The AED
is designed to automatically detect ventricular fibrillation (VF) and perform defibrillation on
victims of sudden cardiac arrest.
Detecting Fibrillation
The electrical rhythm by which the heart muscle contracts can be detected and used for
medical diagnosis and the resulting reading is called an Electrocardiogram (ECG). The
AED has been designed to analyze a patient’
s ECG in order to detect ventricular
fibrillation (VF) in the heart. If ventricular fibrillation (VF) is detected the AED will deliver a
carefully engineered electrical shock designed to stop the chaotic electrical activity
experienced within the heart muscle during SCA. This may allow the victim's heart to
return to a sinus rhythm.
Ventricular Tachycardia / Ventricular Fibrillation
Is a life-threatening heart rhythm that is treatable with the therapy using the AED.
Sinus Rhythm
Sinus Rhythm is the normal electrical rhythm by which the heart muscle contracts and
expands to create blood flow around the body.
Biphasic Shock
A biphasic shock is an electrical current that is passed through the heart, firstly in one
direction and then in another.
Biphasic Truncated Exponential (BTE) waveform
Biphasic Truncated Exponential (BTE) waveform stands for Self-Compensating Output
Pulse Envelope Waveform.
Pads
Pads are the electrodes that are connected to the patient's chest in order to administer
therapy.
