Introduction: Conventional three-lead ambulatory electrocardiogram recording (3L-AECG) is used for the quantitative diagnosis of arrhythmias. However, the lack of crucial information, such as QRS morphology and orientation, renders the 3L-AECG incomplete for planning electrophysiological interventions. The 12-lead AECG (12L-AECG) merges the temporal resolution 3L-AECG with the spatial resolution of the standard electrocardiogram (S-ECG).

Background: Heart failure (HF) with preserved ejection fraction (HFpEF) is associated with enhanced response to drug-induced QT interval lengthening. We determined the influence of HFpEF on drug-induced lengthening of dispersion of repolarization, a measure of proarrhythmic risk.
Methods: We administered intravenous ibutilide 0.

Unlabelled: Hereditary transthyretin amyloidosis is autosomal dominant and results from mutations in the transthyretin gene. The Val30Met variant is the most common genetic mutation, although mutations vary within populations. More than 150 mutations in transthyretin have been reported; however, the Leu111Glu (p.

Background: A notched P-wave is associated with the occurrence of atrial fibrillation (AF). However, the association between a notched P-wave and AF recurrence in patients who have undergone a catheter ablation for AF is unclear.
Methods: We enrolled 100 subjects who underwent catheter ablation for AF (paroxysmal AF: 60 cases; persistent AF: 40 cases).
