Tolerable weekly intake (TWI) estimates the amount per unit body weight of a potentially harmful substance or contaminant in food or water that can be ingested over a lifetime without risk of adverse health effects. [1] [2] TWI is generally preceded by "provisional" to indicate insufficient data exists, increasing uncertainty. [3]
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)
The leads facing the injured cardiac muscle cells will record the action potential as ST elevation during systole while during diastole, there will be depression of the PR segment and the PT segment. Since PR and PT interval are regarded as baseline, ST segment elevation is regarded as a sign of myocardial ischemia.
