T wave hypertrophy
WebJan 30, 2014 · In right bundle-branch block pattern, T waves are inverted in leads V 1 and V 2. In patients with implanted right ventricular pacemakers, inverted T waves are most often seen in leads I and aVL. The T waves are … WebThe T wave in lead V5 and V6 should be upright at all ages, but in a very small number of newborn babies the T wave in these leads may be flat or inverted for 1-3 days. Inversion after this suggests left ventricular hypertrophy (LVH). Tall T waves Hyperkalaemia; LVH; Flat T waves Hypokalaemia; Pericarditis; Myocarditis; Newborns; Hypothyroidism

In V3 to V6, the T wave must be upright. Now turn to the limb leads: If there is a Q wave in I, II, aVL or aVF it should not be more than a quarter of the size of the R wave. Larger Q waves may be found in III and aVR. Abnormal Q waves suggest myocardial infarction, old or recent.
WebThe Q wave is the initial downward deflection; normal Q waves last < 0.05 second in all leads except V1 to V3, in which any Q wave is considered abnormal, indicating past or current infarction. The R wave is the first upward deflection; criteria for normal height or size are not absolute, but taller R waves may be caused by ventricular hypertrophy.

It is frequently sporadic.
Webplace where T waves descend onto the TP isoelectric line9. When a u wave interrupted the T wave before returning to baseline, the QT interval was measured to the nadir of the curve between the T and u waves. The QTc interval was calculated using the Bazett formula; QTc (ms)=QT measured/√RR (where RR is the RR interval). Extended QTc interval was WebOverview. Non specific ST T wave changes refer to changes in the T waves (such as inversion or flattening) and ST segments (such as ST depression) on the electrocardiogram that due not follow an anatomic distribution and are not diagnostic of any one condition.
