Abstract

A transient pseudoatrial dissociation (Deitz-Marques phenomenon) occurring immediately after right atrial pacing in a 44-year-old woman, and spontaneously together with periods of hiccups in a 50-year-old man are presented. The same phenomenon was produced experimentally in three dogs, after rapid diaphragmatic stimulation. The diaphragmatic origin of fibrillary-like waves on standard ECG is argued because of dependence on respiratory phases and because it does not influence the basic sinus rhythm.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
