Research question
How do the design characteristics of conventional implanted pacemakers and leadless pacemakers compare in their ability to maintain reliable operation while minimizing patient risk?
Summary
For decades, traditional pacemakers have helped regulate abnormal heart rhythms using a small implanted generator connected to the heart through electrical leads. While highly effective, these leads can introduce complications such as infections, fractures, blood vessel damage, and difficulties during replacement or removal.
Recent advances in cardiac technology have led to the development of leadless pacemakers: miniature devices implanted directly inside the heart without the need for transvenous leads. As these devices become more capable and widely adopted, this project will investigate whether leadless pacemakers can reduce complications and provide outcomes comparable or superior to traditional pacemakers, while also examining the limitations that may prevent them from becoming the new standard of care.
Why it matters
Leads are one of the most common sources of pacemaker complications. Understanding the design trade-offs between leadless and conventional devices, including how each is implanted, maintained and eventually replaced, helps show where leadless pacing fits in cardiac care.
