Tachycardias originating in the anterior left fascicle would lead to right axis deviation. [citation needed] Right ventricular outflow tract tachycardia originates from the outflow tract of the right ventricle or the tricuspid annulus. As it arises from the right ventricle, the impulse spreads inferiorly from beneath the pulmonary valve, and ...
The ventricular beats typically have a right axis deviation. Multiple morphologies of ventricular tachycardia may be present in the same individual, suggesting multiple arrhythmogenic foci or pathways. Right ventricular outflow tract (RVOT) tachycardia is the most common VT seen in individuals with ACM.
Termed 'cellular-trafficking', this property of the cardiac muscle cell is actually a molecular transformation of the cell to produce a down-regulation of catecolaminergic sensitivity. [11] This means that in the presence of excess epinephrine, a normal cardiac contraction is inhibited in an effort to reduce energy demands, prevent ...
The role of these macrophages is the removal of necrotic myocytes. However, these cells are directly involved in the weakening of the tissue, leading to complications such as a ventricular free wall rupture, intraventricular septum rupture, or a papillary muscle rupture. At a gross anatomical level, this staged is marked by a yellow pallor.
A mnemonic can be used for some causes of ST depression, namely DEPRESSED ST: [citation needed]. D - Drooping valve (mitral valve prolapse) E - Enlargement of the left ventricle P - Potassium loss R - Reciprocal ST depression (e.g. inferior wall MI) E - Encephalon hemorrhage S - Subendocardial infarct S - Subendocardial ischemia E - Embolism (pulmonary) D - Dilated cardiomyopathy S - Shock T ...
A myelodysplastic syndrome (MDS) is one of a group of cancers in which blood cells in the bone marrow do not mature, and as a result, do not develop into healthy blood cells. [3] Early on, no symptoms typically are seen. [3] Later, symptoms may include fatigue, shortness of breath, bleeding disorders, anemia, or frequent infections. [3]
Cardiomegaly can be serious and can result in congestive heart failure. Recent studies suggest that cardiomegaly is associated with a higher risk of sudden cardiac death. [13] Cardiomegaly may diminish over time, but many people with an enlarged heart (dilated cardiomyopathy) need lifelong medication. [14]
Torsades de pointes, torsade de pointes or torsades des pointes (TdP; also called torsades) (/ t ɔːr ˌ s ɑː d d ə ˈ p w æ̃ t /, [2] French: [tɔʁsad də pwɛ̃t̪], translated as "twisting of peaks") is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.
