    Implantable Defibrillators in Octogenarians.,Background: The use of implantable cardioverter-defibrillators (ICDs) in octogenarians is poorly defined. Objective: To assess baseline electrocardiographic (ECG) findings, arrhythmia episodes, and development of severe nonarrhythmic illness or death in patients aged ,80 years at ICD implantation, and to compare them with younger patients. Methods: Medical records and device interrogations for 199 patients ,70 years old who underwent ICD implantation were reviewed. Patients were divided into 3 groups based on age at the time of implant: age 70,74 (group 1; 88 patients), age 75,79 (group 2; 67 patients), and age ,80 (group 3; 44 patients). Results: ECGs: Octogenarians were more likely to have sinus bradycardia (SB) (P = 0.047) and left bundle branch block (LBBB) (P = 0.043) compared to younger patients. There was no difference among groups in the proportion of patients with atrial fibrillation or any degree of AV block. Therapies: There was no difference between age groups in any therapy (P = 0.78), appropriate therapy (P = 0.54), or inappropriate therapy (P = 0.21) per patient-year. There was no difference between groups in time-to-first therapy of any type (P = 0.71). Nonarrhythmic death/morbidity: There was no difference between groups in time to death or serious illness. Conclusion: Our study is the first to evaluate in detail the therapies received by octogenarians after ICD placement. The higher incidence of SB and LBBB might influence the number of pacing sites in octogenarian patients. Very elderly patients have similar rates of arrhythmic episodes and development of severe comorbidities as septuagenarians, and they should not be denied ICD implantation based solely on age.

    ICD: a qualitative study of patient experience the first year after implantation

    JOURNAL OF CLINICAL NURSING, Issue 8 2004
    Helen CM Kamphuis MSc
    Background., The experiences of how patients live with an implantable cardioverter defibrillator are still poorly understood. Only a few qualitative studies have investigated this phenomenon. This paper was undertaken as part of a larger project to evaluate quality of life and psychological well-being in those survivors of cardiac arrest who have received an implantable cardioverter defibrillator. Aims and objectives., The aim of this qualitative study was to explore how implantable cardioverter defibrillator recipients perceive their lives during the first year after implantation of the device. Methods., A sample of 21 patients who received an implantable cardioverter defibrillator was interviewed during three consecutive periods: one, six and 12 months postdischarge from the hospital. The semi-structured interviews were based on insights gained from a literature review. The transcripts were subjected to content analysis. Results., Analysis of the data revealed seven major categories: physical deterioration, cognitive changes, perceived social support, dependency, contact with the doctor, confrontation with mortality and uncertainty surrounding having a shock. Anxiety, uncertainty, disappointment, frustration, unexpected barriers, acceptance of and dependency on the implantable cardioverter defibrillator played a major role in the lives of implantable cardioverter defibrillator recipients. Well-being improved throughout the year. During the first months after discharge from the hospital the focus was on regaining physical health. During the early postimplantation period both the implantable cardioverter defibrillator recipient and family members had adapted to the situation. Reflection on the impact and consequences of the cardiac arrest was reported more often in the late postimplantation period. Conclusions., Content analysis is a resourceful approach giving answers to questions that have hardly been addressed within the domain of cardiology. Implantable cardioverter defibrillator recipients face a complex first year, especially the first 6 months. Cognitive deterioration and confrontation with mortality are problems that need to be researched further. Relevance to clinical practice., Caregivers are able to explain to future patients what they can expect in the first year after implantation. Caregivers may become more receptive to physical, psychological and social limitations and to emotional and social problems that occur in implantable cardioverter defibrillator recipients, enabling them to act upon them.

    Australian implantable cardiac defibrillator recipients: Quality-of-life issues

    INTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 2 2002

    Implantable cardioverter defibrillators (ICDs) have become a well-established therapy for people experiencing potentially lethal dysrhythmias. Australian recipients' quality of life and adjustment to the device over time, device-related complications, shock and associated sensations, and potential sequelae have not been widely explored. This paper reports a longitudinal prospective study of Australian ICD recipients (n = 74) to determine their responses to the device, health-related quality of life over time and shock experiences. A questionnaire designed for the study and the Medical Outcomes Trust Quality of Life Instrument, the SF36, were completed by recipients prior to and at 3 and 12 months post insertion. Results show that quality of life decreased for general health and social function between 3 and 12 months. Nearly half (49%) of the recipients received shocks within 12 months and the majority (92%) of these experienced sequelae that could make driving hazardous. Half of the population (49%) were driving at 3 months and 69% by 12 months, including 67% of those who had been shocked. Twenty-seven percent were hospitalized with device-related complications. Driving, the shock experience and rehospitalization, the shock experience and driving behaviour are significant issues for those with the implanted device. While it is a limitation of the study that partners and carers were not included, these findings will also be of interest to them. [source]

    Background: Atrial rate-adaptive pacing may improve cardiopulmonary reserve in patients with left ventricular dysfunction. Methods: A randomized, blinded, single-crossover design enrolled dual-chamber implantable defibrillator recipients without pacing indications and an ejection fraction ,40% to undergo cardiopulmonary exercise treadmill stress testing in both atrial rate-adaptive pacing (AAIR) and ventricular demand pacing (VVI) pacing modes. The primary endpoint was change in peak oxygen consumption (VO2). Secondary endpoints were changes in anaerobic threshold, perceived exertion, exercise duration, and peak blood pressure. Results: Ten patients, nine males, eight with New York Heart Association class I, mean ejection fraction 24 ± 7%, were analyzed. Baseline VO2 was 3.6 ± 0.5 mL/kg/min. Heart rate at peak exercise was significantly higher during AAIR versus VVI pacing (142 ± 18 vs 130 ± 23 bpm; P = 0.05). However, there was no difference in peak VO2 (AAIR 23.7 ± 6.1 vs VVI 23.8 ± 6.3 mL/kg/min; P = 0.8), anaerobic threshold (AAIR 1.3 ± 0.3 vs VVI 1.2 ± 0.2 L/min; P = 0.11), rate of perceived exertion (AAIR 7.3 ± 1.5 vs VVI 7.8 ± 1.2; P = 0.46), exercise duration (AAIR 15 minutes, 46 seconds ± 2 minutes, 54 seconds vs VVI 16 minutes, 3 seconds ± 2 minutes, 48 seconds; P = 0.38), or peak systolic blood pressure (AAIR 155 ± 22 vs VVI 153 ± 21; P = 0.61) between the two pacing modes. Conclusion: In this study, AAIR pacing did not improve peak VO2, anaerobic threshold, rate of perceived exertion, or exercise duration compared to VVI backup pacing in patients with left ventricular dysfunction and no pacing indications.
