Conduction system pacing: setting the pace
When the heart has an abnormal rhythm, many patients are implanted with a small medical device called a pacemaker, which sends electrical signals that counteract the incorrect ones that are firing off in the heart, which cause the arrhythmia, and stimulate the muscles to make the heart beat at a normal rate. Innovations in the field mean that there are several types of pacemakers available on the market, such as conduction system pacemakers, which can be more effective in less disruptive ways for specific patients.

To the beat of my heart: what to know about conduction system and leadless pacemakers
Pacemakers are small medical devices designed to help manage abnormal heart rhythms, particularly when the heart beats too slowly (a condition known as bradycardia). In recent years, advances in technology have led to new types of pacemakers, including conduction system pacemakers and leadless pacemakers, offering more tailored options for patients depending on their condition and anatomy.

Syncope and pacemakers: How conduction system pacing improves outcomes and quality of life
Fainting, medically known as syncope, can be distressing and disruptive to daily life. While occasional episodes may be harmless, recurrent or unexplained fainting can signal an underlying heart rhythm problem. In this article, a consultant cardiologist and electrophysiologist explains how pacemakers, particularly a modern approach called conduction system pacing, are improving outcomes and restoring quality of life for patients with rhythm-related syncope.

Cardiac pacemakers: Understanding the latest approaches and best options
Cardiac pacemakers are small medical devices that can be implanted to help regulate the heartbeat either to prevent it beating too slowly (bradycardia) or to make it beat in a more coordinated and effective manner (aiming to relieve breathlessness or impaired cardiac function). Pacemakers have undergone significant advancements in recent years. Previously they simply ensured there were not too few heart beats, now pacemakers can work in a far more physiological way and can almost replicate normal conduction. Understanding the latest approaches and options can help those needing a pacemaker make informed decisions about their care.

Solving heart rhythm issues with pacemakers
In his latest online article, Mr Mohamed Al-Obaidi gives us his insights into pacemaker. The human heart, a marvel of natural engineering, relies on an intricate electrical conduction system to maintain its rhythm and functionality. This system includes a natural pacemaker and a network of "wiring" that enables synchronised heartbeats. However, like any complex electrical system, problems can arise over time, leading to a range of cardiac issues. In such cases, the installation of a pacemaker becomes a crucial intervention to address these "wiring" faults and restore the heart's proper rhythm and function.

Everything you need to know about pacemakers
Pacemakers are devices which work to regulate the heartbeat and statistics show that over half a million people in the UK have the pacemakers implanted. Leading consultant Allan Harkness explains everything you need to know about pacemakers, including how they work and their history, as well as the most recent developments in pacemaker technology.

Restoring heart rhythm
The human heart is a marvel of biological engineering, with its intricate electrical conduction system responsible for maintaining a steady heartbeat. However, just like any other electrical system, the heart's own wiring can encounter problems over time, leading to slow or irregular heart rhythms. In such cases, a medical marvel known as a pacemaker comes to the rescue, offering a way to overcome these "wiring" faults and restore the heart's rhythm. In his latest online article, Dr Mohamed Al- Obaidi explores the importance of pacemakers in addressing heart rhythm issues and sheds light on the procedure involved in implanting these life-saving devices.

How loop recorders are key to cardiac arrythmia diagnosis
If you experience a fluttering sensation in the chest, or a racing heartbeat, for example, it could mean cardiac arrhythmia. And to ensure you get the right diagnosis, further analysis with an implantable loop recorder could be required. Dr Jonathan Behar, a leading London-based cardiologist goes into expert detail on the role of the loop recorder.

A comprehensive history of arrhythmia treatment
The first surgical option for arrhythmia was implantation of a pacemaker. It has been highly successful for people whose arrhythmia is due to the heart going too slowly. Some cardiogists believe that pacemakers are underused because many people have a heart that is going slower than would be most efficient. They are often held back by vague symptoms including fatigued or not sleeping well because the heart slows down too much which then causes the brain to speed up. This tells the heart by producing adrenaline, which in turn wakes the rest of the brain. As a result, people have disturbed sleep, similar to sleep aponea.
