  • 1.The Epocrates-conducted survey reports that in lieu of the recent CMS decision to halt reimbursements to hospitals for the treatment of potentially avoidable surgical site infections following cardiac implantable electronic device (CIED) procedures – which include pacemaker and defibrillator implants – hospital CFOs are contemplating new technologies.

  • 2.Results of an international trial suggest that combining a biventricular pacemaker with an implantable cardioverter-defibrillator (ICD) — a device that can shock the heart out of a potentially lethal rhythm — helps prevent deaths from sudden cardiac arrest and hospitalizations for heart failure better than an ICD alone (New England Journal of Medicine, Dec. 16, 2010). The downside of this double therapy is an increase in hospitalizations due to problems with the devices.

  • 3.The device gathers energy from these vibrations and transforms it to electricity. The electrical signals are then transmitted to the heart to keep it beating in a healthy rhythm and to power an implanted defibrillator or pacemaker. .

  • 4.The implantable cardioverter–defibrillator (ICD) is highly effective in reducing mortality among patients at risk for fatal arrhythmias, but inappropriate ICD activations are frequent, with potential adverse effects.

    植入性心律转复除颤器( ICD))可有效减少致命性心律失常高风险患者的死亡率,但非适当放电治疗事件如果频繁发生,就可能带来潜在的不良事件。

  • 5.Results from RATE, presented by Dr StevenSwiryn (Northwestern University, Chicago, IL) at last week's American HeartAssociation 2012 Scientific Sessions, showed that patients with cardiac rhythm control deviceswho only experience short episodes of AT/AF areat about the same risk for adverse events as otherwise-similar patients who never experience an episode of AT/AF.However, the data Swiryn presentedshowed that any long episode of AT/AF is associated with a higher risk ofhospitalization for clinical AT/AF in implantable cardioverter defibrillator[医]埋藏式复律除颤器(ICD) and pacemakerpatients. Also, greater frequency of AT/AF episodes is associated with higher risk ofany adverse events and higher risk of AF hospitalization in ICD patients.

    Steven Swiryn博士在上周举行的美国心脏病学会2012年科学会议上发布来自RATE的研究结果。结果显示,安装了心脏节律控制设备的患者只会发生短期的AT或AF,这些病人发生不良事件的风险与其他类似的不会出现AT或AF的患者相似。然而,Swiryn发布的数据显示,长期存在AT或AF与安装了ICD和起搏器的患者因发生AT或AF住院的高风险有关。发生AT或AF的高频率与不良事件的高风险和安装了ICD的患者因AF入院的高风险有关。
