Cardiac pacemakers are routinely used for the treatment of bradyarrhythmias. Contemporary pacemakers are reliable and allow for a patient specific programming. However, pacemaker replacements due to battery depletion are common (~25 % of all implantation procedures) and bear the risk of complications. Batteryless pacemakers may allow overcoming this limitation. To power a batteryless pacemaker, a mechanism for intracorporeal energy harvesting is required. Such a generator may consist out of subcutaneously implanted solar cells, transforming the small amount of transcutaneously available light into electrical energy. Alternatively, intravascular turbines may harvest energy from the blood flow. Energy may also be harvested from the ventricular wall motion by a dedicated mechanical clockwork converting motion into electrical energy. All these approaches have successfully been tested in vivo. Pacemaker leads constitute another Achilles heel of contemporary pacemakers. Thus, leadless devices are desired. Miniaturized pacemaker circuits and suitable energy harvesting mechanisms (incorporated in a single device) may allow catheter-based implantation of the pacemaker in the heart. Such miniaturized battery- and leadless pacemakers would combine the advantages of both approaches and overcome major limitations of today’s systems.

The benefits of permanent cardiac pacing have been widely demonstrated. However, the literature on complications remains inconsistent. We lack precise information about the frequency of complications and their predictive factors in our center.

Background: Cardiac implantable devices (CIED) such as pacemakers, implantable cardioverter-defibrillators, or cardiac resynchronization devices are implanted in selected patients with bradyarrhythmia and advanced heart failure. The invasive character of these procedures poses a risk of early complications such as pneumothorax, bleeding, infections, or dislocations.
Aims: There are no available data that analyzed the impact of the organization of procedures on the early complications risk after permanent pacing procedures.

Aim: The association of cardiac implantable electronic devices (CIED), namely pacemaker (PM), implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy with (CRT-D) or without defibrillator (CRT-P) with health-related quality of life (HRQoL) is lacking.
Methods And Results: Data from the Swedish Pacemaker and ICD Registry collected from January 2019 to February 2022 was used to analyze the responses to the European Quality of Life-5 Dimension questionnaire (EQ-5D) before and after one year of the CIED implant. Descriptive analysis was performed using Pearson's chi-square test, the analysis of variance ANOVA, the Kruskal-Wallis test and Wilcoxon signed-rank test when appropriate.

Background: Brady- and tachyarrhythmias commonly complicate adult congenital heart disease (ACHD). Permanent pacemakers (PPMs) or implantable cardioverter-defibrillators (ICDs) are often utilised to prevent morbidity or mortality related to arrhythmia, but can also be associated with significant morbidity themselves.
Methods: We analysed outcomes from patients in our comprehensive ACHD database who were seen at least twice since 2000 and once since 2018.

Vasovagal syncope (VVS), characterized by transient loss of consciousness, is among the most prevalent reasons for emergency visits worldwide. Although benign in nature, VVS can be accompanied by traumatic injury, leading to morbidity and decreased quality of life, especially in those with VVS recurrence. The management includes non-pharmacologic and pharmacologic therapies (if resistant), patient education and reassurance, salt and fluid intake increase, and physical counter-pressure maneuvers.
