Diseases
The symptoms of anemia
What is Tiredness, Weakness, Shortness of breath, Pale or yellowish skin, which might be more obvious on white skin than on Black or brown skin, Irregular heartbeat, Dizziness or lightheadedness, Chest pain, Cold hands and feet.
Electrocardiography
What is test to record the electrical signals in the heart. It shows how the heart is beating. Sticky patches called electrodes are placed on the chest and sometimes on the arms or legs
Tachycardia
what is a heart rate over 100 beats a minute. Many types of irregular heart rhythms, called arrhythmias, can cause tachycardia
Arteries
Vessels throughout the body that expand and contract as they carry fresh, oxygenated blood away from the heart
Four Main Parts of the Circulatory System
Heart, blood vessels, blood, and Lymphatic system
Signs of cardiac arrest
What is Fatigue, Dizziness, Shortness of breath, Nausea, Chest pain, Heart palpitations (fast or pounding heart beat), Loss of consciousness.
MUGA Scan
What is a test that uses a radioactive material that targets the heart, along with a gamma camera and a computer, to create images of the blood flowing through the heart
Bradycardia
What is slower-than-expected heart rate, generally beating fewer than 60 beats per minute.
Arterioles
Connect arteries to
capillaries
Anatomy of the Heart
Located behind the sternum and in between the lungs. Two-thirds of the heart is on the left side of the chest
Symptoms of Coronary Heart Disease
What is chest pain (angina), shortness of breath, pain in your neck, shoulders, jaw or arms, feeling faint, feeling sick (nausea)
Echocardiogram
What is an ultrasound test that checks the structure and function of your heart. An echo can diagnose a range of conditions including cardiomyopathy and valve disease.
Pacemaker
What is a small device used to treat some arrhythmias. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. Pacemakers send electrical pulses to help your heart beat at a normal rate and rhythm
Capillaries
Oxygen-rich blood enters the capillary bed, where the exchange of gasses occurs.When blood leaves the capillary bed, it carries away carbon dioxide and waste
Heart Sounds
Lub- First sound, Caused by the valves slamming shut, between the atria and ventricles
dub- Second sound, Caused by the closure of the semilunar, valves closing in the aorta and pulmonary, arteries
Cause of Aplastic Anemia
What is injury or destruction of the blood cell formation by the bone marrow
Cardiac CT Scan
Can show the structure and function of the heart and blood vessels. It can help detect heart disease, blockages, and other abnormalities.
Heart Murmur
Heart murmur can have causes that aren't due to underlying disease. Examples include turbulence resulting in a flow murmur or thickening of the aortic valve that occurs with aging.
Veins
Similar to arteries, but the walls are thinner and they lack elastic fibers. Veins carry deoxygenated blood back to the heart
Cholesterol
Substance in blood from fat metabolism, Accumulates on lining of blood vessels in the form of plaque
Cause of a Heart Attack
What is high blood pressure, diabetes, smoking, high cholesterol
Cardiac Catheterization
What is a test or treatment for certain heart or blood vessel problems, such as clogged arteries or irregular heartbeats
Atrial fibrillation
What is the most common heart rhythm disorder. It occurs when the upper chambers of the heart quiver and beat irregularly.
Venules
Join together with the capillaries to form veins that eventually enter the heart through the vena cava.
Blood types
A, B, AB, O
