Ejection Fraction is a measurement of how much blood a heart chamber pumps out with each heartbeat. It is most commonly used to describe how well the left ventricle pumps blood to the body. Clinicians often discuss it when evaluating heart failure, cardiomyopathy, and recovery after a heart attack. It is usually reported as a percentage from an imaging test.
C2 level refers to the second cervical vertebra region in the neck. It is commonly used to describe an anatomic location on imaging, exams, and surgical plans. Clinicians also use it to localize nerves, joints, and the spinal cord near the upper cervical spine. In plain terms, it means “at the level of the second neck bone.”
Stroke Volume is the amount of blood the heart ejects with each heartbeat. It is most often discussed for the left ventricle, the main pumping chamber that sends blood to the body. Clinicians use it to understand how effectively the heart is pumping in different conditions. It is commonly referenced in echocardiograms, intensive care monitoring, and heart failure evaluations.
The C2 vertebra is the second bone in the cervical spine (neck). It is also called the axis, and it sits just below C1 (the atlas). C2 vertebra helps the head rotate and supports the upper spinal cord. The term is commonly used in anatomy, imaging reports, and neck injury care.
Cardiac Output is the amount of blood the heart pumps each minute. It reflects how well the heart and circulation deliver oxygen and nutrients to the body. Clinicians use it to understand symptoms like shortness of breath, fatigue, and lightheadedness. It is also used in hospitals to monitor people who are critically ill or recovering from major heart problems.
Heart Rate is the number of times the heart beats in one minute. It is most often reported as “beats per minute” (bpm). It is used in everyday health tracking and in clinical care to describe how fast the heart is working. Clinicians interpret it alongside symptoms, blood pressure, oxygen level, and heart rhythm.
Valve Prolapse is a structural heart valve finding where a valve leaflet bows backward beyond its usual closing line. It is most commonly discussed in the mitral valve, but it can involve other heart valves. Clinicians use the term when interpreting physical exams and heart imaging, especially echocardiography. Valve Prolapse may be an incidental finding or part of a broader valve disorder that includes leakage (regurgitation).
C2 is the second cervical vertebra in the neck, also called the axis. It sits just below C1 (the atlas) at the top of the spine. C2 is best known for its “dens” (odontoid process), which helps the head rotate. The term C2 is used in anatomy, imaging reports, and spine diagnoses and procedures.
The C1 nerve root is the first cervical spinal nerve that exits at the top of the neck, between the skull and the first cervical vertebra (C1, the atlas). It carries nerve signals that help control and coordinate muscles and sensations in the upper neck and back of the head region. Clinicians most often discuss it in the context of upper cervical anatomy, headache/neck pain evaluation, and certain spine procedures and surgeries near C0–C2. It is also important in understanding how nerves interact with the upper cervical joints and surrounding muscles.
Valve Stenosis means a heart valve opening has become abnormally narrow. A narrowed valve makes it harder for blood to move forward through the heart. It is most commonly discussed as aortic stenosis or mitral stenosis. The term is used in cardiology visits, echocardiogram reports, and surgical or catheter-based planning.
