title: [Atrial complex in bronchial ECG leads].
abstract: The authors suggest a probe electrode by means of which the ECG may be recorded in the bronchial leads simultaneously from four levels of the atrioventricular zone. The P wave of bronchial ECG's was analysed in 24 patients who had no pathological changes in the respiratory organs and cardiovascular system in comparison with similar indices of routine ECG's. The informativeness of ECG's recorded in the bronchial leads in study of the bioelectric activity of the right and left atria is determined. It is pointed out that esophageal leads may be used for analysing the electric activity of the right atrium when they are recorded from the level of an electrode (28.5--31.5 cm) introduced into the esophagus.
