Defibrillator Icd
Diabetics Should Consult Their Doctors
Different Types and Uses of a DefibrillatorA defibrillator is one very essential medical device. When a patient experiences ventricular fibrillation or ventricular tachycardia and thus dangerously fast and chaotic heartbeat, defibrillation is done to restore a normal heart rhythm. Also, patients with arrhythmogenic right ventricular dysplasia, cardiomyopathy, QT syndromes and survivors of sudden cardiac death need defibrillation. Using defibrillators help prevent cases of cardiac arrest and cardiac death.
For life-threatening cardiac arrhythmias ventricular fibrillation and pulseless ventricular tachycardia, defibrillation is the definitive treatment. In this treatment, a defibrillator is used to deliver a therapeutic dose of electrical energy to the affected heart. Before the affected heart suffers from sudden cardiac arrest, defibrillation works to restore normal heart rhythms. It depolarizes a critical mass of the heart muscle, ends the arrhythmia, and reestablishes normal sinus rhythm.

Medtronic Inc. said Tuesday a U.S. District Court dismissed with prejudice lawsuits over lead wires to an implantable defibrillator on the grounds that Food and Drug Administration approval protects the makers from lawsuits. In October of 2007 ...
Defibrillators come in various shapes and sizes. What you commonly see in the hospital are called manual defibrillators or defibrillator paddles, and they are used by healthcare professionals. The AED or automatic external defibrillators are those that allow lay people to operate it with only minimal training. This is perfect for emergency uses. Implantable cardioverter defibrillators or ICDS are implanted in a patient’s chest.
There are both internal and external manual defibrillators. The clinician diagnoses a cardiac condition through external units that work in conjunction with electrocardiogram readers. After the diagnosis, the clinician then decides on the charge in joules to deliver to the patient’s chest, and sends the shock through pads or paddles. Medical knowledge and experience is needed to perform this treatment, thus they are only generally found in hospitals and some ambulances.
Manual internal defibrillators are just about identical to the external version. The difference is that the charge is delivered through internal leads attached to the heart. The leads are used to detect when the heart is experiencing a rhythm that demands a shock, and to deliver the shock. Generally, you can find these units exclusively in operating rooms, where the chest is likely to be open, or can be quickly opened by a surgeon.

For emergency cases where no healthcare professional is around, AEDs are available. Automated external defibrillators are based on computer technology to study the heart rhythm and advise whether a shock is necessary. Unlike manual types, AEDs can be used by lay persons with less training. PADs or public access defibrillators are AEDs that can be found in public places including airports, hotels, and shopping centers. There are also some AEDs which are held by trained personnel who will attend incidents.
ICDs or implantable cardio-verter defibrillators are another form. Such units are implantable (patient’s chest), and can perform the same function as pacemaking. ICDs regularly check on the patient’s heart rhythm, and if required, also corrects arrhythmia or abnormal heart rhythm based on the device’s programming. The pacemaker can be used together with ICDs for events that involve treating complex arrhythmias.
Those are the different types and uses of a defibrillator. But although they are different in shape and size, all of them have a specific goal. That is to convert an unhealthy cardiac rhythm into a more normal rhythm. And whether, it is used by medical professionals or lay men, external or internal, automatic or manual, it helps lessen incidences of cardiac arrest or cardiac death.
