What causes segmental wall motion abnormalities?
The most frequent cause of regional wall motion abnormality is ischemic heart disease. Myocardial infarction may cause regional hypokinesia, akinesia or dyskinesia. The distribution of wall motion abnormalities should match the territory of a coronary artery.
What is abnormal heart wall motion?
Abnormal ventricular wall motion is a strong clinical predictor of sudden, arrhythmic, cardiac death. Dispersion in repolarization is a prerequisite for the initiation of re-entrant arrhythmia. We hypothesize that regionally decreased wall motion is associated with heterogeneity of repolarization.
What is heart Swma?
SWMA was defined by the presence of akinesia or moderate to severe hypokinesia in at least two segments. Patients were divided into one of two groups according to the presence (SWMA group) or the absence (non-SMWA group) of SWMA.
What is WM in ECG?
WM indicates wall motion; BMI, body mass index; CHD, coronary heart disease; MI, myocardial infarction; CVD, cardiovascular disease; BP, blood pressure; HDL, high-density lipoprotein; and U Alb/Crea, urinary albumin/creatinine ratio.
What is segmental wall motion abnormalities?
Segmental wall motion abnormality was defined as a localized area of the left ventricular wall that moved abnormally compared with adjacent walls and was described as akinetic, dyskinetic or hypokinetic.
What does abnormal septal motion mean?
Abnormal septal motion (ASM), or septal bouncing, is a paradoxical bouncing motion of the interventricular septum. 1) During early diastolic period, interventricular septum initially directed towards and moves away from the left ventricle. ASM can be found frequently during echocardiographic examinations.
What is mild LV systolic dysfunction?
LV systolic dysfunction was defined as an ejection fraction (EF) of less than 40% by echocardiography. The recovery of LV systolic function was defined as recovery of the EF to a level of 40% or greater and a net increase in EF of 10% or greater.
What can affect an ECG reading?
These include:
- Obesity.
- Anatomical considerations, such as the size of the chest and the location of the heart within the chest.
- Movement during the test.
- Exercise or smoking before the test.
- Certain medicines.
- Electrolyte imbalances, such as too much or too little potassium, magnesium, or calcium in the blood.
What is septal motion?
Overview. Paradoxical septal motion is defined as movement of the interventricular septum away from the left ventricular free wall during systole which is the opposite of its normal movement which is inward toward the left ventricle / or the left ventricular free wall during systole.
What are the different types of ST segment abnormalities?
ST segment depression is often characterized as “horizontal”, “upsloping”, or “downsloping” Reciprocal changes in acute Q-wave MI (e.g., ST depression in leads I & aVL with acute inferior MI) RVH (right precordial leads) or LVH (left precordial leads, I, aVL) Secondary ST segment changes with IV conduction abnormalities (e.g., RBBB, LBBB, WPW, etc)
What are the results of segmental vertebral anomalies?
Two other patients underwent only conventional myelography. RESULTS: Segmental vertebral anomalies involved the thoracolumbar, lumbar, or lumbosacral spine. The spinal cord at the level of the abnormality was thinned or even indiscernible, and a bulky, low-lying cord segment was present caudad to the focal abnormality in most cases.
What do you need to know about segmental spinal dysgenesis?
BACKGROUND AND PURPOSE: Segmental spinal dysgenesis (SSD) is a rare congenital abnormality in which a segment of the spine and spinal cord fails to develop properly.
What are the different types of ST segment depression?
Pseudo-ST-depression (wandering baseline due to poor skin-electrode contact) Physiologic J-junctional depression with sinus tachycardia (most likely due to atrial repolarization) Hyperventilation-induced ST segment depression ST segment depression is often characterized as “horizontal”, “upsloping”, or “downsloping”
