Inverted T wave is considered abnormal if inversion is deeper than 1.0 mm. Inverted T waves found in leads other than the V1 to V4 leads is associated with increased cardiac deaths. Inverted T waves associated with cardiac signs and symptoms ( chest pain and cardiac murmur ) are highly suggestive of myocardial ischaemia . [ 4 ]
English: The twelve leads of a twelve-lead electrocardiogram are shown here with the contiguous leads shown in the same color: Pink — aVR; Orange — septal leads (V1, V2) Yellow — inferior leads (II, III, aVF) Green — lateral leads (I, aVL, V5, V6) Blue — anterior leads (V3, V4)
Damage to the thalamus can lead to permanent coma. [38] The role of the thalamus in the more anterior pallidal and nigral territories in the basal ganglia system disturbances is recognized but still poorly understood. The contribution of the thalamus to vestibular or to tectal functions is almost ignored. The thalamus has been thought of as a ...
It may be defined, for example, as R wave of less than 2–4 mm in leads V 3 or V 4 and/or presence of a reversed R wave progression, which is defined as R in V 4 < R in V 3 or R in V 3 < R in V 2 or R in V 2 < R in V 1, or any combination of these. [11]

The anterolateral central arteries or lenticulostriate arteries [3] (also anterolateral perforating arteries, anterolateral ganglionic arteries, striate arteries, or lateral striate arteries; latin aa. centrales anterolaterales, [4] or aa. lenticulostriatae [4]) are a group of small arteries mostly arising from (the initial M1 part of) the middle cerebral artery that enter the brain through ...
Ramos is the lead author of a new study of older adults of Latin descent that found people with sleep apnea may have an enlarged hippocampus, which is the area of the brain responsible for memory ...
