Vascular dementia. Vascular dementia is dementia caused by a series of strokes. [ 2 ][ 4 ] Restricted blood flow due to strokes reduces oxygen and glucose delivery to the brain, causing cell injury and neurological deficits in the affected region. [ 6 ] Subtypes of vascular dementia include subcortical vascular dementia, multi-infarct dementia ...
[1] [2] Hyperkalemia can cause an abnormal heart rhythm which can result in cardiac arrest and death. [1] [3] Common causes of hyperkalemia include kidney failure, hypoaldosteronism, and rhabdomyolysis. [1] A number of medications can also cause high blood potassium including spironolactone, NSAIDs, and angiotensin converting enzyme inhibitors. [1]
Use of real time monitoring of the heart in an intensive care unit in a German hospital (2015), the monitoring screen above the patient displaying an electrocardiogram and various values of parameters of the heart like heart rate and blood pressure. Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a ...
Prognosis. Variable; average survival 4 years from diagnosis [ 8 ] Frequency. About 0.4% of persons older than 65 [ 9 ] Dementia with Lewy bodies (DLB) is a type of dementia characterized by changes in sleep, behavior, cognition, movement, and regulation of automatic bodily functions. Memory loss is not always an early symptom.
Left axis deviation. The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
YOAD. Specialty. Neurology. Early-onset Alzheimer's disease (EOAD), also called younger-onset Alzheimer's disease (YOAD), [1] is Alzheimer's disease diagnosed before the age of 65. [2] It is an uncommon form of Alzheimer's, accounting for only 5–10% of all Alzheimer's cases. About 60% have a positive family history of Alzheimer's and 13% of ...
Right axis deviation. 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. The hexaxial reference system can be used to ...
Diagram showing how the polarity of the QRS complex in leads I, II, and III can be used to estimate the heart's electrical axis in the frontal plane. The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing.
