The term ‘flutter’ was coined to designate the visual and tactile rapid, regular atrial contraction induced by faradic stimulation in animal hearts, in contrast with irregular, vermiform contraction in atrial fibrillation (AF).1,2 On the ECG, flutter was a regular continuous undulation between QRS complexes at a cycle length (CL) of ≤250 ms (≥240 bpm). Slower tachycardias displaying discrete P…

Although the exact circuit of atrioventricular nodal re-entrant tachycardia (AVNRT) still eludes us, AVNRT is the most common regular arrhythmia in humans, and therefore the most commonly encountered during ablation attempts for regular tachycardias.1–4 Catheter ablation for AVNRT is the current treatment of choice in symptomatic patients. It reduces arrhythmia-related hospitalisations and costs,…

Pioneering electrophysiology studies in the 1990s defined the anatomical boundaries of typical atrial flutter, identified regions for effective catheter ablation of this arrhythmia and described procedural endpoints to minimise recurrences after ablation. Activation and entrainment mapping demonstrated that typical flutter arises from reentry around the tricuspid annulus.1 Criteria to confirm…

Around 0.8% of live births are affected by some type of congenital heart disease; 30–50% of whom will need one or more surgical interventions, generally during early childhood, involving in some cases complex corrections with patches, baffles or extracardiac circuits.1,2
As a result of advances in surgical interventions, the life expectancy of patients with congenital heart disease has…

The reported incidence of congenital heart disease (CHD) depends on the number of trivial lesions included, such as atrial and ventricular septal defects (ASDs and VSDs). Moderate-to-severe CHD numbers remain stable with 6 per 1,000 live births.1 Survival into adulthood has improved dramatically over the last 25 years and has been driven mainly by a decreased mortality in moderate and severe…

Ventricular tachycardia (VT) originating from the Purkinje system is the most common type of idiopathic left ventricular tachycardia (ILVT), especially among young Asians.1,2 It usually has a benign course. Research over the past two decades has deepened our understanding of the anatomy of the Purkinje system and the mechanisms of ILVT. This review focuses on the research history and anatomy of…
