what is an abnormal ejection fraction?
1438
It pumps oxygen-rich blood up into the upward (ascending) aorta to the rest of the body. An LV ejection fraction of 55 percent or higher is considered normal. An LV ejection fraction of 50 percent or lower is considered reduced. An LV ejection fraction between 50 and 55 percent is usually considered "borderline."

This situation presents usually a concentric hypertrophy. In contrast, systolic heart failure has usually an eccentric hypertrophy. Diastolic failure is characterized by an elevated diastolic pressure in the left ventricle, despite an essentially normal/physiologic end diastolic volume (EDV).

An echogenic intracardiac focus (EIF) is a bright white spot in the fetal heart that looks like a tiny golf ball. This bright spot is due to a bit of calcium in one of the muscles that attaches to the heart valve. It is NOT an abnormality and is NOT associated with heart defects.

An ejection fraction measurement higher than 75 percent may indicate a heart condition such as hypertrophic cardiomyopathy.

Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.

Normal: Less than 120 systolic and less than 80 diastolic. Elevated: 120-129 systolic and less than 80 diastolic.

40 to 55% – Below normal heart function. Can indicate previous heart damage from heart attack or cardiomyopathy. Higher than 75% – Can indicate a heart condition like hypertrophic cardiomyopathy, a common cause of sudden cardiac arrest. Less than 40% – May confirm the diagnosis of heart failure.

A healthy heart will alternately speed up and slow down to compensate for the over- and under-filling that follows a VPB until the amount of blood filling the heart returns to normal. Abnormal heart rate turbulence occurs when the heart can't compensate in this way.

Low Ejection Fraction Causes Coronary artery disease: This heart disease narrows or blocks the two main arteries that supply blood to your heart muscle. Learn more about coronary artery disease. Heart attack: Blockage of the heart's arteries can permanently damage your heart muscle.

Good news! Many people with a low ejection fraction (or EF) have successfully improved it. Better heart failure management (HF) can lead to a better ejection fraction.

Fractional shortening (FS) is the fraction of any diastolic dimension that is lost in systole.

The most common abnormal heart sound is a heart murmur. A murmur is a blowing, whooshing, or rasping sound that occurs during your heartbeat. There are two kinds of heart murmurs: innocent (also called physiological)

Heart failure with preserved ejection fraction (HFpEF), also called diastolic failure (or diastolic dysfunction): The left ventricle loses its ability to relax normally (because the muscle has become stiff). The heart can't properly fill with blood during the resting period between each beat.

This is the mildest form of diastolic heart failure and is referred to as an abnormal relaxation pattern. Patients are usually asymptomatic. Grade II – This diastolic dysfunction is characterized by increased filling pressure in the atrium and is considered to be moderate stage disease.

Sometimes an EKG abnormality is a normal variation of a heart's rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.

Pathophysiology – Mitral Regurgitation When blood abnormally flows backward from the left ventricle to the left atrium, the volume of both chambers increases. Because a significant volume of blood is flowing retrograde, forward cardiac output decreases despite the left ventricular ejection fraction appearing normal.
