The second device is the implantable cardioverter defibrillator(ICD), which works by noticing when the heart is converting into an unwanted rhythm and shocking the heart until it returns to its normal rhythm. Although an ICD has some similarities to the pacemaker it also has some big differences. The pacemaker and ICD are both implanted the same way, just under the skin of the chest or in the abdomen. Implanting the device is a minor procedure today and is common. Most people only need to stay in the hospital a day or two. They both also are pacemakers so, 2,3,4,6they can help stop fast and slow rhythms. The pacemaker and ICD both have a generator and a lead or leads. The pacemaker will steady a heartbeat whereas an ICD 2,4,6will reset the

When comparing the CRT 3,5,6,7 and pacemaker the main similarity is that they both are pacemakers that send impulses to stimulate contraction of the ventricles, each have a generator with leads connecting it the ventricles. The main difference between the cardiac pacemaker and the CRT is that there are two leads to the ventricles, one to the left and one on the right, which restores the 4,6,7contraction of the left and right ventricle at the same time. This allows an even flow of blood through both chambers with better cardiac output. This is also called biventricular pacing. The CRT has the added bonus of offering defibrillation therapy(CRT-D) and the benefit of the third lead. The defibrillators in the CRT-D can shock the heart rhythm back to normal if it senses dangerous fast rhythms. CRT-D can improve the pump 6,7function of the heart and reduce ventricular remodeling. The CRT works by providing electrical impulses that are sent to the left and right 6,7ventricle to improve the timing. Like the pacemaker and ICD the CRT-D generator is implanted in the chest or abdomen. The indications of the CRT and CRT-D are to treat dangerous ventricular arrhythmias, ventricular defibrillation, atrial tachyarrhythmia, heart muscle damage, AV blocks, 2,3,4,5,,7,cardiomyopathy, and antitachycardia. With that being said the CRT-D is used mainly for heart failure along with other life threatening disorder such as VT 6,7ventricular tachyarrhythmia. CRT is also for intraventricular conduction abnormalities that have a wide QRS complexes especially, like a left bundle block which can be 4common in many patients with advanced heart failure. CRT is a great device to treat symptomatic heart failure from systolic 4,7dysfuntion. Patients that have a CRT will see an improvement in the
