  • 1. Implantable cardioverter defibrillator (ICD)Defibrillator Implant-DefibrillationImplantable cardioverter defibrillators (ICD), or simply justdefibrillators are devices that are designed primarily to carry outanti-tachyarrhythmia therapy (tachyarrhythmimia andtachyarrhythmia therapy will be explained in next articles).ICD isa device used to detect and instantly stop the malignant heartrhythm disorders. The system consists of a housing containing abattery and electronic circuit and a catheter containing electrodesthat are placed in the heart. This process is known asdefibrillation. Implantable cardioverter defibrillator’s housing isplaced under the skin in the area under the (usually left) clavicle.What kind of defibrillator a patient will get and how it will be setprimarily depends on patient’s medical history, physical condition, condition of heart and acondition of cardiac muscle cells.Implantable cardioverter defibrillator can instantly recognize a heart rhythm disorder (mostoften it is an accelerated working ventricular – ventricular tachycardia or heart flutter –ventricular fibrillation) and immediately respond to with stimulation (by pulses that interrupt rapidheartbeat) or with an electrical shock (by defibrillation). The success of Implantable cardioverterdefibrillation intervention is very high, above 98%. In addition, the ICD serves as a “normal”electrostimulator, pacemaker, and its intervention can prevent slow beats.In addition to therapeutic intervention, the ICD’s memory stores a series of data on the rhythmof the patient, which allows further treatment options (correction of drug therapy – plavix,aspirin, the procedure known as “Ablation”, the programming of the device, etc.). Implantablecardioverter defibrillator operates continuously, 24 hours a day. The ICD’s placement surgeryprocedure is same as cardiac pacemaker surgery and biventricular pacemaker surgeryprocedure.Implantable Cardioverter Defibrillator SurgeryICD placing (defibrillation) is a small surgical procedure under local anesthesia. Surgery is inplace for this specialized, electrophysiological laboratories. Before surgery patient intravenouslygets an antibiotic and an anesthetic. The implantable cardioverter defibrillator surgery is doneunder the full awareness of a patient.On a leg groin incision is made ​​to enter into a vein through which the wire is placed in the heartwhile a generator is placed below the collarbone with a small incision. Then wires and generatorare connected. At the end of the installation the patient is pun under the general anesthesia inorder to test the ability of the device to stop malicious rhythm disturbance, ventricular fibrillation.By testing device, ventricular fibrillation is manually caused, the device recognizes andinterrupts it. A patient can typically go home the next day. For precautions on this matter you
  • 2. can educate yourself on Blood Types and ABO blood group system article.The device control is performed at certain intervals (every 6 months) or after the patient noticedan intervention (electric shock most people can recognize good).Some patients with heart failure may benefit from a combination of cardiac resynchronizationtherapy (CRT) and an implantable cardiac defibrillator (ICD). These devices combinebiventricular pacing with anti-tachycardia pacing and internal defibrillators to deliver treatmentas needed.Copyright from http://FeelGoodTime.net All rights reserved.
