Interatrial block can occur in the absence of left atrial enlargement: New experimental model. Pacing and Clinical Electrophysiology, 43(4), 427–429. https://doi.org/10.1111/pace.138950147-83891540-8159http://hdl.handle.net/11268/8969We present the surface electrocardiogram of an open‐chest anesthetized healthy adult swine after direct application of ice at the transversus sinus of the pericardium where the Bachmann's region is located. Gradual and transient interatrial block (IAB) in the absence of structural atrial disease is described. This new experimental model demonstrated that IAB is an independent entity from left atrial enlargement.engjournal article10.1111/pace.13895restricted accessCardiologíaEnfermedadesElectrocardiografíaEnfermedad cardiovascularTecnología médica
