Automated External Defibrillators: Heart Conditions That AEDs Treat

Saturday , 22, February 2020 Comments Off on Automated External Defibrillators: Heart Conditions That AEDs Treat

AEDs or automated external defibrillators are portable devices that are capable of diagnosing heart problems like tachycardia and ventricular fibrillation. The AED is able to treat these symptoms after diagnosing the arrhythmia through the procedure of defibrillation, which is the method through which energy is used to restart the heart, eventually enabling the heart to achieve a stable rhythm. Pulseless ventricular tachycardia and ventricular fibrillation are the two disorders which can be handled through the automated external defibrillator. aed cabinet

The first of these factors is the source of cardiac arrest, which is pulseless ventricular tachycardia. Ventricular tachycardia starts in one of the ventricles of the heart and is associated with increased, faster heart beating which contributes to arrhythmia. Tachycardia is known to cause asystole, ventricular fibrillation and death. As the name implies, pulseless ventricular tachycardia consists of a complete halt in the heart beating which leads to cardiac arrest. That does not indicate that the heart’s electrical activity has stopped. The activity however is so weak that there is no discernible heart output.

Lightheadedness and the loss of consciousness are common symptoms of pulseless ventricular tachycardia. Individuals feel shortness of breath when their heart starts picking up tempo to an irregular rhythm. The AED is used to jump start the heart to preserve the heart’s regular rhythmic pounding. By applying electric pulses the AED defibrillates the heart.

The second condition, ventricular fibrillation, happens when the heart muscle is not contracting in a coordinated fashion. The electrical activity does not disappear immediately but is usually undetectable to non-medical people at the femoral or carotid arteries. The occurrence of ventricular fibrillation may be diagnosed using electrocardiography or an external defibrillator which is automated. If ventricular fibrillation is not treated soon after it occurs, it will often degenerate into asystole, meaning that an electrocardiogram does not record any electrical cardiac activity. It is very unlikely for a victim to be resurrected once this occurs unless the person is very lucky and there is some residual movement which can be harnessed. Within just a few minutes of the start of ventricular fibrillation, blood will cease pumping and sudden cardiac death or SCD is inevitable.
