Reuse of pacemakers and implantable cardioverter-defibrillators: systematic review, meta-analysis and quality assessment of the body of evidence.

Expert Rev Med Devices 2021 May 9. Epub 2021 May 9.

University of São Paulo - USP. Nursing School. Av. Dr. Enéas Carvalho de Aguiar, 419 - Cerqueira César, CEP 05403-000, São Paulo, SP, Brazil.

: Pacemakers (PMs) and implantable cardioverter-defibrillators (ICDs) have reduced mortality and improved the quality of life of cardiac patients. However, the high cost of these devices prevents their large-scale incorporation, particularly in low-income countries, where reusing explanted PMs/ICDs has become an alternative.: A systematic review and meta-analysis were conducted of studies that compare infection rates, device-related deaths, malfunction and premature battery depletion in patients with reused PM and ICD implants and those with new devices.

[50 years of electrophysiology and cardiac pacing].

G Ital Cardiol (Rome) 2021 May;22(5):341-351

U.O.C. Cardiologia, Ospedale G.B. Grassi, Ostia (RM).

During the last 50 years a continuous improvement was observed in the field of cardiac pacing and electrophysiology as for as both technological and clinical aspects were concerned. We moved from the first recording of the His bundle electrogram to the identification of the various mechanisms and sites of supraventricular and ventricular tachyarrhythmias, to three-dimensional mapping and ablation of different reentry circuits and eventually to pulmonary vein isolation for the treatment of atrial fibrillation. As far as cardiac pacing is concerned, we moved from single chamber to dual chamber pacing, to ventricular pacing and implantable automatic defibrillators provided by sophisticated diagnostic and therapeutic algorithms and by remote control.

Physical Activity Patterns Among Patients with Intracardiac Remote Monitoring Devices Before, During, and After COVID-19-related Public Health Restrictions.

medRxiv 2021 Mar 1. Epub 2021 Mar 1.

Nationwide public health restrictions due to the coronavirus disease 2019 (COVID-19) pandemic have disrupted people's routine physical activities, yet little objective information is available on the extent to which physical activity has changed among patients with pre-existing cardiac diseases. Using remote monitoring data of 9,924 patients with pacemakers and implantable cardiac defibrillators (ICDs) living in New York City and Minneapolis/Saint Paul, we assessed physical activity patterns among these patients in 2019 and 2020 from January through October. We found marked declines in physical activity among patients with implantable cardiac devices during COVID-19-related restrictions and the reduction was consistent across age and sex subgroups.

[Pacemakers and defibrillators: what the non-specialist needs to know].

Rev Med Suisse 2021 Mar;17(728):444-448

Service de cardiologie, Hôpital Riviera-Chablais, 1847 Rennaz.

Cardiologists are in charge of the follow-up of patients equipped with pacemakers and defibrillators. In many situations, however, the non-specialist will have to take care of these patients. It is therefore essential that the practitioner understands the basics of how these devices work, the potential complications and the situations in which the cardiologist's intervention is necessary.

Recommendations for participation in leisure-time physical activity and competitive sports in patients with arrhythmias and potentially arrhythmogenic conditions: Part 1: Supraventricular arrhythmias. A position statement of the Section of Sports Cardiology and Exercise from the European Association of Preventive Cardiology (EAPC) and the European Heart Rhythm Association (EHRA), both associations of the European Society of Cardiology.

Eur J Prev Cardiol 2020 Jun 29. Epub 2020 Jun 29.

Italian National Olympic Committee, Institute of Sport Medicine and Science, Italy.

Symptoms attributable to arrhythmias are frequently encountered in clinical practice. Cardiologists and sport physicians are required to identify high-risk individuals harbouring such conditions and provide appropriate advice regarding participation in regular exercise programmes and competitive sport. The three aspects that need to be considered are: (a) the risk of life-threatening arrhythmias by participating in sports; (b) control of symptoms due to arrhythmias that are not life-threatening but may hamper performance and/or reduce the quality of life; and (c) the impact of sports on the natural progression of the underlying arrhythmogenic condition.
