Septal deflection
WebInterventricular septal involvement in myocardial infarction is suggested by the findings of a QS deflection in lead V1 and/or absence of the Q wave in leads I and V6, using the standard 12-lead electrocardiogram (ECG). However, these findings were not sufficiently established for the criteria of septal infarction, because several factors ... A deviated septum occurs when the thin wall (nasal septum) between your nasal passages is displaced to one side. In many people, the nasal septum is off-center — or deviated — making one nasal passage smaller. When a deviated septum is severe, it can block one side of the nose and reduce airflow, … See more Most septal displacements result in no symptoms, and you may not even know you have a deviated septum.

WebBackground: In the absence of other electrocardiographic (ECG) abnormalities, QS deflections simultaneously in both of the leads V1-V2 may have multiple possible causes. Despite much information in the literature indicating that this is an unlikely pattern for pure septal infarction, such an ECG diagnosis is frequently given.

A septoplasty is performed to improve air flow through the nose, does not change the cosmetic appearance. There appears to be other issues causing nasal obstruction other than a deviated septum.
