title: [Diagnostic value of the bipolar esophageal electrocardiographic lead for detection of disorders of cardiac rhythm and conductivity at rest, during physical exercise and with Valsalva's maneuver].
abstract: Diagnosis of some heart rhythm disorders is based on bipolar esophageal ECG lead that can detect a P wave of greater amplitude, as compared to the QRS complex. The diagnostic value of bipolar esophageal ECG lead is in that it provides a more reliable assessment of pacemaker localization (both nomotopic and heterotopic), the sinoatrial node rhythm, extrasystole localization, type and mechanism of paroxysmal tachycardias, as well as antegrade and retrograde (ventricle-to-atrium) impulse conduction. Bipolar esophageal ECG lead records contribute to correct assessment of cardiac rhythm and conductivity disorders at rest as well as during exercise and Valsalva's test.
