As the number of patients having implantable cardioverter defibrillator (ICD) devices is increasing, it is important for the physicians and patients to be aware of situations and conditions that can result in interference with normal functioning of these devices. There are multiple cases of malfunction of ICDs reported in literature and it may be of great significance to have an overview of these incidents for appropriate recognition and future prevention. Here we are reviewing the available literature as well as reporting an interesting case of electromagnetic interference (EMI) resulting from leak of current in pool water causing firing of ICD.

Introduction A number of patients are excluded from electrical stimulation treatment because there is concern that electrical stimulation could cause electromagnetic interference with pacemakers and implanted cardioverter defibrillators. The decision to use electrical stimulation in these patients needs to be supported by an assessment of benefit and harm. Methods We conducted a systematic review of the risk of electromagnetic interference between electrical stimulation and pacemakers or implanted cardioverter defibrillators. We included the electronic databases MEDLINE and EMBASE in the time period between 1966 and 26 August 2016. Results 18 papers fulfilled the inclusion criteria (eight safety studies and ten case studies). Although we were unable to accurately estimate the risk of electromagnetic interference, the studies revealed that patients having electrical stimulation of the lower limb are less susceptible to electromagnetic interference. Conclusions The results suggest that electrical stimulation could be used safely to help drop foot in patients with pacemakers or implanted cardioverter defibrillators. However, in order to obtain an accurate estimate of the risk of electromagnetic interference, a large, long-term, and intervention-specific safety study is required. Until such a study is undertaken, electrical stimulation should be used with caution in patients with pacemakers and implanted cardioverter defibrillators.

AbstractFollowing the sudden death of a friend in 1966, Dr Michel Mirowski began pioneering work on the first implantable cardioverter-defibrillator. By 1969 he had developed an experimental model and performed the first transvenous defibrillation. In 1970 he reported on the use of a “standby automatic defibrillator” that was tested successfully in dogs. He postulated that such a device “when adapted for clinical use, might be implanted temporarily or permanently in selected patients particularly prone to develop ventricular fibrillation and thus provide them with some degree of protection from sudden coronary death”. In 1980 he reported on the first human implants of an “electronic device designed to monitor cardiac electrical activity, to recognise ventricular fibrillation and ventricular tachyarrhythmias … and then to deliver corrective defibrillatory discharges”. Through innovations in circuitry, battery, and capacitor technologies, the current implantable cardioverter-defibrillator is 10 times smaller and exponentially more sophisticated than that first iteration. This article will review the inner workings of the implantable cardioverter-defibrillator and outline several features that make it the wonder in technology that it has become.

Background/Objectives: Implantable cardioverter defibrillators are used to prevent sudden cardiac death. The subcutaneous implantable cardioverter defibrillator was newly developed to overcome the limitations of the conventional implantable cardioverter defibrillator-transvenous device. The subcutaneous implantable cardioverter defibrillator is indicated for young patients with heart disease, congenital heart defects, and poor venous access, who have an indication for implantable cardioverter defibrillator without the need for anti-bradycardic stimulation. We aimed to compare the efficacy and complications of subcutaneous with transvenous implantable cardioverter defibrillator devices. Methodology: A systematic review was conducted using different databases. The inclusion criteria were observational and clinical randomized trials with no language limits and no publication date limit that compared subcutaneous with transvenous implantable cardioverter defibrillators. The selected patients were aged > 18 years with complex ventricular arrhythmia. Results : Five studies involving 2111 patients who underwent implantable cardioverter defibrillator implantation were included. The most frequent complication in the subcutaneous device group was infection, followed by hematoma formation and electrode migration. For the transvenous device, the most frequent complications were electrode migration and infection. Regarding efficacy, the total rates of appropriate shocks were 9.04% and 20.47% in the subcutaneous and transvenous device groups, respectively, whereas inappropriate shocks to the subcutaneous and transvenous device groups were 11,3% and 10,7%, respectively. Conclusion: When compared to the transvenous device, the subcutaneous device had lower complication rates owing to lead migration and less inappropriate shocks due to supraventricular tachycardia; nevertheless, infection rates and improper shocks due to T wave oversensing were comparable for both devices

BACKGROUND: The long-term outcomes of living with an implantable cardioverter defibrillator are an important consideration in recovery. However, little is known about physical and psychosocial outcomes beyond 1 year after implantation. OBJECTIVE: To describe the long-term physical and psychosocial adaptation of persons who have had an implantable cardioverter defibrillator for approximately 2 years or more. METHODS: This nonexperimental cross-sectional study used telephone interviews to ascertain the responses of 80 recipients of implantable cardioverter defibrillators to physical and psychosocial questionnaires to explore the long-term outcomes of living with the devices. Subjects eligible for inclusion were selected from the files of an arrhythmia clinic. RESULTS: Hierarchical regression analysis showed that subjects who are not emotional are likely to be more physically active, especially if they are young and male, and that subjects who tend to be emotional are likely to be psychologically distressed and have poorer social and domestic adaptation. Furthermore, use of emotions was a positive predictor of psychological distress and poor social and domestic adaptation. Subjects reported the use of both emotion- and problem-focused coping. Subjects' scores on physical and psychosocial functioning were comparable to scores reported in the literature for patients who have had myocardial infarction or dysrhythmia. CONCLUSIONS: Emotional responses to distress were predictive of little physical activity and psychological distress. Furthermore, young recipients of implantable cardioverter defibrillators and men were predicted to be physically active. Persons who have had an implantable cardioverter defibrillator for approximately 2 years or more can anticipate that their physical and psychosocial functioning will be similar to that of patients who have myocardial infarction or dysrhythmia.

The use of implantable cardioverter-defibrillators (ICD) has increased due to benefits of preventing death from cardiac arrhythmia. However, the increasing use of ICDs has created new challenges for how to proactively manage deactivation of these devices in people who are dying, especially for those who lack capacity to make decisions about their care. The aim of this case report is to discuss the challenges of planning for deactivation of an ICD for a patient who lacked capacity at the end of life. We describe the challenges of managing ICD deactivation in a dying patient with fluctuating capacity who had previously expressed a wish for the ICD to remain active. Although it is preferable to use advance care planning (ACP), to provide care in-line with patient-identified care preferences, we demonstrate how a best interest process can be used to make decisions about ICD deactivation at the end of life.
