Lipid rescue for bupivacaine toxicity during cardiovascular procedures

Background: Conduction system pacing has the potential to offer improved outcomes compared with other forms of pacing. His bundle pacing (HBP) can be technically more difficult to achieve and pacing thresholds can be unreliable compared with left bundle branch area ...

Background: Conduction system pacing is a novel pacing technique that aims to maintain physiological activation of the ventricles. It can be achieved by pacing the His-bundle or the left bundle branch area. Left bundle branch area pacing (LBBAP) has many ...

The global disease burden of atrial fibrillation (AF) is considerable, and a significant proportion is attributable to the associated thromboembolic risk. The pro-thrombotic environment resulting from AF accrues a five-fold increase in stroke risk, with the arrhythmia implicated in 30% of ...

The clinical introduction of cardiac electrophysiology (EP) studies in the 1980s was a cornerstone in how to understand, diagnose and treat specific arrhythmias. Anatomic orientation and positioning of catheters was achieved by fluoroscopic guidance. Signals were derived from intracardiac EP-catheters ...

Presentation A 73-year-old female with a history of recent bio-prosthetic aortic valve replacement, stroke, hypertension, breast cancer status post-lumpectomy and radiotherapy, and hyperlipidemia was admitted with shortness of breath and tachycardia. Her blood pressure (BP) was 147/65 and her pulse was 105/...

Short QT syndrome (SQTS) is a cardiac channelopathy characterised by an abnormally short QT interval and an increased risk of atrial and ventricular fibrillation.1 As it often involves young patients with an apparently normal heart, it is imperative for physicians ...

Long QT syndrome (LQTS) is a hereditary disorder characterised by prolongation of the QT interval on electrocardiogram (ECG), syncope and sudden death due to torsade de pointes (Tdp) and/ or ventricular fibrillation.1 To date, 16 genes have been reported as LQTS-causing ...

The atrial transseptal puncture (TSP) technique is an indispensable procedure in the invasive cardiac catheterisation laboratory. TSP was initially developed in 1959 by Ross, Braunwald and Morrow at the National Institutes of Health, to allow for catheter access to the left ...

Premature ventricular contractions (PVCs) arising from the Purkinje network are rare causes of idiopathic ventricular fibrillation (IVF).1–4Van Herendael and colleagues recently highlighted the importance of triggers from the papillary muscles (PM) and the left ventricular outflow tract in the ...

Current use of QRS duration in cardiac resynchronization therapy Cardiac resynchronization therapy (CRT) is an established therapeutic option in patients with symptomatic systolic heart failure concomitant with electrical dyssynchrony.1–3 Patients with a wide QRS (≥120 ms), especially those with a left ...

Case Presentation This case concerns a 24-year-old female with recurrent episodes of paroxysmal palpitations. Her physical exam, 12-lead electrocardiogram (ECG), 24-hour Holter monitoring and echocardiogram did not reveal any abnormality. In the last 2 years, she had several admissions to the ...
