Physiological pacing: just a lot of buzz or the next paradigm shift in bradycardia pacing?

Cardiac pacing has been an established therapy for bradyarrhythmia due to sinus or atrioventricular nodal disease since the 1950s. However, contemporary studies have shown that conventional right ventricular pacing (RVP) causes electromechanical dyssynchrony, which can lead to atrial fibrillation, heart failure and even death. Recently, the push for a more physiological cardiac pacing has seen a revival in the utilisation and development of conduction system pacing (CSP).

Contemporary wearable and handheld technology for the diagnosis of cardiac arrhythmias in Singapore.

Twelve-lead electrocardiography (ECG) remains the gold standard for the diagnosis of cardiac arrhythmias. It provides a snapshot of the cardiac electrical activity while the leads are attached to the patient. As medical training is required to use the ECG machine, its use remains restricted to the clinic and hospital settings.

Practical and systematic approach using the steerable catheter and stylet-driven lead to deliver safe and effective left bundle branch area pacing.

Introduction: Current delivery tools were not designed for left bundle branch area pacing (LBBAP). Challenges using these tools include lack of reach into the right ventricle and poor support for the lead to penetrate the interventricular septum. Concerns using stylet-driven leads (SDL) for LBBAP have been previously highlighted.

Tachy- and bradyarrhythmia as an initial presentation of human immunodeficiency virus-related primary cardiac lymphoma: a case report.

Background: Primary cardiac lymphoma is defined as extranodal lymphoma involving the heart or pericardium. Common presentations of human immunodeficiency virus (HIV)-associated cardiac lymphoma include heart failure, cardiac tamponade, and rhythm abnormalities. Arrhythmia is an uncommon presentation and treatment in young HIV patients is particularly challenging.

A case report: use of cerebral oximetry in the early detection of cerebral hypoperfusion in a post-cardiac arrest patient during targeted temperature management.

Background: We present a patient who received cerebral oximetry monitoring during targeted temperature management (TTM) post-cardiac arrest and discuss its potential in the early detection of cerebral hypoperfusion and implications on haemodynamics and ventilatory management.

Case Summary: A 60-year-old Chinese male was admitted for acute pulmonary oedema with Type 2 respiratory failure. He failed an initial trial of non-invasive ventilation and was planned for intubation and mechanical ventilation.
