Familial neonatal atrial tachycardia

Concurrent maternal and fetal tachyarrhythmia in pregnancy

The occurrence of a maternal and fetal tachyarrhythmia together in pregnancy is exceedingly rare. We report a case of a persistent fetal atrial ectopic tachycardia occurring in conjunction with a maternal atrial tachycardia with left ventricular systolic dysfunction. Amiodarone was effective in treating both maternal and fetal arrhythmias.

A new hereditary form of ectopic atrial tachycardia with autosomal dominant inheritance

We report a family with a previously not described hereditary form of ectopic atrial tachycardia. The tachycardia had an autosomal dominant mode of inheritance, was not associated with structural heart disease and had a benign course.
