Always consult your doctor for a diagnosis. If a Type 2 pattern is seen, the ECG needs to repeated to ensure proper lead placement, and a repeat ECG with V1 and V2 in higher intercostal leads should be performed: if there is no evidence of a Type 1 Brugada pattern, no further assessment is required unless there is a history of syncope or relevant family history. borderline/ normal ecg As it is to be supposed, the dilation of the Left Atrium produces, in most cases, changes in the Pwave, especially in its final component. Wide P wave with prominent negative component. Left atrial enlargement (LAE) is a marker for diastolic cardiac dysfunction. This condition is usually harmless and does not shorten life expectancy. The Septal Q wave can hint on a possible left sided disease if any. Conditions affecting the left side of the heart. Left atrial abnormality on the electrocardiogram (ECG) has been considered an early sign of hypertensive heart disease. In fact, it has been considered that the bimodal P wave is better explained because of underlying interatrial block than the longer distance that the impulse has to go across6. 2009;doi:10.1161/CIRCULATIONAHA.108.191095.
