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…

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…

Atrioventricular nodal reentrant tachycardia (AVNRT) denotes re-entry in the area of the AV node, and represents the most common regular arrhythmia in the human.1 Although several models have been proposed to explain the mechanism of the arrhythmia in the context of the complex anatomy and the anisotropic properties of the atrioventricular (AV) node and its atrial extensions (see Figure 1),2 the…

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,…

Dear Sir,
I read with great interest the elegant review written by Dr Efimov and colleagues on the structure and properties of the atrioventricular (AV) node in the last issue of this journal (AER 6(4):179–85).1 However, there are several points that need further clarification.
The authors state that total protein and mRNA levels of Cx40, Cx43 and/or Cx45 can be assessed qualitatively and…

In this video interview, Dr Parikshit Sharma (Rush University Medical Center, Chicago, IL, US) discusses the clinical outcomes from the Geisinger-Rush Conduction System Pacing Registry, presented at ESC's Heart Rhythm Society 2021. This was a non-randomized, observational cohort registry, which aimed to compare the results of left bundle branch area pacing compared to right ventricular pacing in…
