Measuring child rhythm.

Accelerated idioventricular rhythm associated with propranolol treatment in a child.

Accelerated idioventricular rhythm (AIVR) is a ventricular arrhythmia most commonly seen in adults with underlying cardiac disease. It is important to establish the diagnosis when it occurs to differentiate this benign phenomenon from dangerous ventricular tachycardia. We present the case of a healthy child who developed episodes of AIVR associated with propranolol treatment. Her 24-hour el...

Measuring speech rhythm variation in a model-based framework

A coupled-oscillators-model-based method for measuring speech rhythm is presented. This model explains crosslinguistic differences in rhythm as deriving from varying degrees of coupling strength between a syllable oscillator and a phrase stress oscillator. The method was applied to three texts read aloud in French, in Brazilian and European Portuguese by seven speakers. The results reproduce th...

Right ventricular resynchronization in a child with hypoplastic left heart syndrome.

Critical validation studies of neurofeedback.

The field of neurofeedback training has proceeded largely without validation. In this article the authors review studies directed at validating sensory motor rhythm, beta and alpha-theta protocols for improving attention, memory, and music performance in healthy participants. Importantly, benefits were demonstrable with cognitive and neurophysiologic measures that were predicted on the basis of...

Spontaneous Resolution of Junctional Rhythm in a Child with Dengue Fever

Atypical manifestations of dengue fever are rising but they may be under reported. In dengue hemorrhagic fever (DHF), cardiac rhythm abnormalities observed were ventricular arrhythmia, atrial fibrillation and atrioventricular block. Here we report an 11 year old boy who presented with dengue fever and developed bradycardia and hypotension. His electrocardiogram (ECG), during the bradycardia, sh...
