How many segments are in the heart?
What are the major segments of the heart?
The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.
What is heart segmentation?
Cardiac CT Image Segmentation. CT is a non-invasive imaging technique that is performed routinely for disease diagnosis and treatment planning. In particular, cardiac CT scans are used for the assessment of cardiac anatomy and specifically the coronary arteries.Mar 5, 2020
How many segments does an echocardiogram have?
Standardized myocardial segmentation and nomenclature for echocardiography. The left ventricle is divided into 17 segments for 2D echocardiography. One can identify these segments in multiple views. The basal part is divided into six segments of 60° each.
What is septal Hypokinesia?
Hypokinesia is a type of movement disorder. It specifically means that your movements have a “decreased amplitude” or aren't as big as you'd expect them to be. Hypokinesia is related to akinesia, which means absence of movement, and bradykinesia, which means slowness of movement.Sep 12, 2017
What are the 4 main arteries of the heart?
The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries. Blockage of these arteries is a common cause of angina, heart disease, heart attacks and heart failure.
What is segmentation deep learning?
Segmentation is the process of determining the boundaries and areas of objects in images. We humans perform segmentation without conscious effort, but it remains a key challenge for machine learning systems.May 7, 2021
What is Inferolateral wall?
Inferolateral: Below and to one side. Both inferior and lateral. In anatomy, there are many such compound terms.
What are the heart muscles?
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
What is LVEF in cardiology?
Left ventricular ejection fraction (LVEF) is the measurement of how much blood is being pumped out of the left ventricle of the heart (the main pumping chamber) with each contraction.Apr 29, 2019

What can ischemia lead to?
Myocardial ischemia can lead to serious complications, including: Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.May 5, 2021

What is regional wall motion abnormality?
Regional wall motion abnormalities are defined as regional abnormalities in contractile function. Ischemic heart disease is the most common cause of wall motion abnormalities. Assessment of wall motion abnormalities is particularly important in the setting of chronic or acute coronary artery disease.
