[Transesophageal precardiac electrostimulation in a functional study of the sinus node]

The transoesophageal electrostimulation of the heart has been used to evaluate the function of the sinus node in 103 patients. The artificial rhythm was enforced in 94.2% of cases. The syndrome of sinus node weakness was diagnosed in 32 patients. The transoesophageal electrostimulation of the atria is a safe and simple method for diagnosis of functional sinus node disorders.
