Frequently Asked Questions
Defibrillator Analyzers
What is the function of a defibrillator Analyzer?
The function of the defibrillator analyzer is to test the energy and other functions of a defibrillator. Since there are many different types of defibrillators in the market, it is important to discuss and understand the major differences and some of the terminologies used to differentiate them. The following are some of the frequently used terminologies associated with various defibrillators.
What is Energy?:
Energy discharged by a defibrillator is expressed in Joules. The unit of joule is defined as one am of current passed through one ohm of resistance in one second.
What is Current?:
Current is what passes though the body when defibrillation occurs to resuscitate a heart. It is expressed as Voltage /Impedance.
What is Impedance?:
Impedance referenced here is the thoracic impedance of a patient undergoing defibrillation. It varies from patient to patient and the quality of contact between the patients body and the paddle (disposable pads used in AEDs).
What are the differences of discharged waveform?
- Monophasic Waveform: It is a type of defibrillation waveform delivered to the heart as shown below. It is graphically a representation of current and time.

What is the difference between the Delta 2000 and the Delta 3000A?
The Delta 2000 defibrillator analyzer can test the full function of all biphasic Defibrillators. It measures energy, cadioversion time. Delta 3000A defibrillator analyzer not only tests all functions of biphasic and monophonic defibrillators as well as the transthoracic Pacing functions such as pulse rate and amplitude (current).
The Delta 3000A will test all the functions associated with
Emergency Defibrillators including Automatic Mode and Pacer Mode. The
built-in ECG simulator is ideal for testing the functions of monitors. Delta 3000A
What is cardio version?
Electrical cardio-version is a procedure whereby a synchronized (perfectly timed on the rising edge of the Q wave of the ECG) electrical shock is delivered through the chest wall to the heart through special electrodes or paddles that are applied to the skin of the chest and back. Cardio version measurement is in in milliseconds. Positive reading indicates it is on the rising edge of the Q wave. Negative reading indicates it is fired on the falling edge of the Q wave.
The goal of the
cardio-version is to disrupt the abnormal electrical circuit's) in the
heart and to restore a normal heart beat. The shock causes all the heart
cells to contract simultaneously, thereby interrupting and terminating
the abnormal electrical rhythm (typically fibrillation of the atria)
without damaging the heart. This split second interruption of the
abnormal beat allows the heart's electrical system to regain control and
restore a normal heartbeat.
