Tear gland: The gland that makes tears. An abnormality of the tear glands can impair the production of the tears and lead to dry eyes.Also called a lacrimal gland.ear gland: The gland that makes tears. An abnormality of the tear glands can impair the production of the tears and lead to dry eyes.
The four main causes of left axis deviation (LAD): 1  Left anterior fascicular block (LAFB): 2  Diagnostic criteria include: 3  Mean QRS axis from - 45 to - 90 (possibly. 4  A qR pattern in lead aVL, with the R-peak time, i.e., the onset of the Q wave to the peak of the R wave. 5  45 msec (slightly more than one small box wide).
1 Axis deviation â QRS widening with changes in QRS morphology â and peaked T wave inversion are all examples of ECG abnormalities that may simply be due to the hyperkalemia. However, the most remarkable finding are the very tall, peaked T waves with narrow base (Eiffel Tower effect) in several precordial leads (Figure 2). 2  This strongly suggests Hyperkalemia.
