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…

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…

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…

Prevalence of AF and Obstructive Sleep Apnoea
Nonvalvular AF is the most common sustained arrhythmia, affecting nearly 3 million adult Americans.1–4 By 2050, nearly 12–15 million adults in the US will have AF.1 The global prevalence of obstructive sleep apnoea (OSA) is also increasing. OSA is the most common form of sleep-disordered breathing, affecting 10–15% of the general population (6–9% in…

Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide. In 2010, the prevalence of AF in the US was estimated at 5.9 million.1 The decision to pursue treatment to maintain sinus rhythm is driven by disabling symptoms related to AF; including palpitations, dyspnoea, fatigue, stroke and congestive heart failure. Percutaneous catheter-based ablation is an established therapy for…

AF is a common and clinically impactful arrhythmia. Given both the association of AF with aging and the increasing number of elderly people in the general population, it follows that many AF patients are of advanced age. The management of AF in the geriatric population is associated with several challenges, including multiple comorbidities, increased toxicity of antiarrhythmic drugs (AAD), an…

Pulmonary hypertension (PH) is a chronic condition that is characterised by elevated pulmonary vascular pressures and can be caused by several disease processes (see Table 1).1 Regardless of the aetiology, PH is a progressive disease with a clinical course characterised by frequent decompensations in advanced stages and often a poor prognosis despite the development of novel therapeutic agents.2…
