The LAD gives off two types of branches: septals and diagonals. Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the anterior 2/3 of the interventricular septum. Diagonals run along the surface of the heart and supply the lateral wall of the left ventricle and the anterolateral papillary muscle.
Mechanical shifts that cause LAD are expiration or raised diaphragm from pregnancy, ascites (fluid accumulation in the abdomen), abdominal tumor, or enlarged liver or spleen. [2] Left axis deviation is a border deviation in athletes , which, if it is combined with another borderline feature such as right bundle branch block, requires further ...

Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
Medical symptoms refer to the manifestations or indications of a disease or condition, perceived and complained about by the patient. [ 1 ] [ 2 ] Patients observe these symptoms and seek medical advice from healthcare professionals.
Leukocyte adhesion deficiency (LAD) is a rare autosomal recessive disorder characterized by immunodeficiency resulting in recurrent infections. [1] LAD is currently divided into three subtypes: LAD1 , LAD2 , and the recently described LAD3 , also known as LAD-1/variant.
The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG).Normally, this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart.
A dose of under 100 rad will typically produce no immediate symptoms other than blood changes. A dose of 100 to 200 rad delivered to the entire body in less than a day may cause acute radiation syndrome (ARS), but is usually not fatal. Doses of 200 to 1,000 rad delivered in a few hours will cause serious illness, with poor prognosis at the ...
