A Review of the Recent Advances of Cardiac Pacemaker Technology in Handling Complications

Abstract

The total number of annual pacemaker implantations continues to grow globally, and help patients with heart rhythm disorders with an improved quality of life and reduced mortality. The first implantable pacemakers appeared in 1965, characterized by their bulkiness, short battery life, and a single pacing mode. Innovation led to the modern pacemaker: a smaller system with improved battery life and capacity, and innovation in lead technology. Certain arrhythmia conditions may also qualify for leadless pacemaker implantation, thus eliminating the spectrum of complications that could occur with leads. Adverse events can be divided into acute (perforation, lead dislodgement, infection) and long-term (lead fractures, device infection, insulation failure). Traditional long-term complications with leads occur in 10% of patients, compared with device-related adverse effects observed in 6.7% of leadless pacemakers. Furthermore, cardiac pacemaker implantation results in quality of life improvements across all age groups. Large cardiac rehabilitation studies have demonstrated the effectiveness of exercise in reducing the physical complications involved with pacemaker implantation. Of the three randomized controlled trials examined, all of them reported some benefit of exercise in the intervention group compared with the control. The following review aims to discuss the multitude of pacemaker options potentially available for the clinician, complications, their course of management, and the path forward with innovations arising out of previous research within the field.

Navigating the Complexity: A Comprehensive Review of Managing Pregnancy in Complete Heart Block Cases

“…The dynamic changes in cardiac demand during pregnancy necessitate pacemakers that can adapt and respond to these fluctuations. Innovations in pacing technology are poised to provide more robust and flexible solutions, ensuring that pacemakers can effectively meet the unique cardiovascular needs of pregnant individuals, ultimately contributing to improved maternal and fetal outcomes [ 45 ].…”
