Defibrillator - Internal Defibrillators.
The device may be implanted directly in the user of the device. If so, it is known as an implantable cardioverter-defibrillator or (much less frequently) an internal cardiac defibrillator (ICD). This type of defibrillator is designed to provide immediate defibrillation to high-risk patients. By actively monitoring the pulse rate, rhythm, and waveform, and by comparing atrial and ventricular activity, in ICD can detect ventricular fibrillation, and immediately initiate defibrillation.

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - Frequency too high/low A heart rate faster than 100 beats/minute is considered a tachycardia. With exercise the sinus node increases its rate of electrical activity to accelerate the heart rate. The normal fast rate that develops is called sinus tachycardia. Arrhythmias that are due to fast, abnormal electrical activity can cause tachycardias that are dangerous. If the ventricles of the heart experiences one of these tachycardias for a long period of time, there can be deleterious effects. Individuals may sense a tachycardia as a pounding sensation of the heart, k ...

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - Diagnosis Cardiac dysrhythmias are often first detected by simple but nonspecific means: auscultation of the heartbeat with a stethoscope, or feeling for peripheral pulses. These cannot usually diagnose specific dysrhythmias, but can give a general indication of the heart rate and whether it is regular or irregular. Not all the electrical impulses of the heart produce audible or palpable beats; in many cardiac arrhythmias, the premature or abnormal beats do not produce an effective pumpin ...

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - SADS SADS, or sudden arrhythmia death syndrome, is a term used to describe sudden death due to cardiac arrest brought on by an arrhythmia. The most common cause of sudden death in the US is coronary artery disease. Approximately 300,000 people die suddenly of this cause every year in the US. SADS can also occur from other causes. Tragically there are many inherited condictions and heart diseases that can affect young people that can cause sudden death. Many of these vict ...

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - Antiarrhythmic therapies There are many classes of antiarrhythmic medications and many individual drugs within these classes. See the article on antiarrhythmic agents.
Dysrhythmias may also be treated electrically. Cardioversion is the application of electrical current across the chest wall to the heart and it is used for treatment of supraventricular or pulsed ventricular tachycardia. Defibrillation differs in that it is used for ventricular fibrillation and pulseless ventricular tachycardia, and more electricity is delivered with defibrillation than ...

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - Origin of impulse When an electrical impulse begins in any part of the heart, it will spread throughout the myocardium and cause a contraction; see Electrical conduction system of the heart. Abnormal impulses can begin by one of two mechanisms: automaticity or reentry.
Cardiac arrhythmia - Automaticity.
Automaticity refers to a cardiac muscle cell firing off an impulse on its own. Every cardiac cell has this potential: if it does not receive any impulses from elsewhere, its internal "pacemaker" will fire off an impul ...

| | | | Implantable cardioverter-defibrillator: Encyclopedia II - Cardiac arrhythmia - Fibrillation A serious variety of arrhythmia is known as fibrillation. Fibrillation occurs when the heart muscle begins a quivering motion instead of a normal, healthy pumping rhythm. Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation); ventricular fibrillation is imminently life-threatening.
Atrial fibrillation is the quivering, chaotic motion in the upper chambers of the heart, known as the atria. Atrial fibrillation is often due to serious underlying medical conditions, and should be evaluated by a ...
