What's normal? A normal heart's ejection fraction may be between 50 and 70 percent. You can have a normal ejection fraction measurement and still have heart failure (called HFpEF or heart failure with preserved ejection fraction).

The left ventricle is the heart's main pumping chamber. 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.

Laboratories measure troponin in nanograms per milliliter of blood (ng/ml). The University of Washington's Department of Laboratory Medicine provides the following ranges for troponin I levels: Normal range: below 0.04 ng/ml. Probable heart attack: above 0.40 ng/ml.

While it can change from minute to minute with changes in posture, exercise, stress or sleep, it should normally be less than 120/80 mm Hg for women age 20 or over. Here's how the numbers are evaluated: Normal: Less than 120 systolic and less than 80 diastolic. Elevated: 120-129 systolic and less than 80 diastolic.

The normal percentage of blood ejected from the heart is in the range of 50-70% depending on different factors. If the left ventricular ejection fraction (LVEF) is 45% (& that is not a measurement error), then it is mildly reduced.

Normal: Less than 120 systolic and less than 80 diastolic. Elevated: 120-129 systolic and less than 80 diastolic. High Blood Pressure (Hypertension) Stage 1: 130-139 systolic or 80-89 diastolic. High Blood Pressure (Hypertension) Stage 2: 140 or higher systolic or 90 or higher diastolic.

The normal ranges of blood pressure response to exercise stress testing are as shown in Figure 1. Normal systolic and diastolic responses to exercise stress testing should not exceed 220 and 100 mm Hg, respectively. Systolic blood pressure of >230 mm Hg is generally considered hazardous.

What do EF results mean? A normal LVEF reading for adults over 20 years of age is 53 to 73 percent. An LVEF of below 53 percent for women and 52 percent for men is considered low. An RVEF of less than 45 percent is considered a potential indicator of heart issues.

Grade I (impaired relaxation): This is a normal finding and occurs in nearly 100% of individuals by the age of 60. The E wave velocity is reduced resulting in E/A reversal (ratio < 1.0). The left atrial pressures are normal. The deceleration time of the E wave is prolonged measuring > 200 ms.

Hypertension stages Normal: systolic less than 120 mm Hg and diastolic less than 80 mm Hg. Elevated: systolic between 120-129 mm Hg and diastolic less than 80 mm Hg. Stage 1: systolic between 130-139 mm Hg or diastolic between 80-89 mm Hg. Stage 2: systolic at least 140 mm Hg or diastolic at least 90 mm Hg.

Echocardiogram. This is the most common test used to measure ejection fraction. During an echocardiogram, sound waves are used to produce images of your heart and the blood pumping through your heart.

A normal level of NT-proBNP, based on Cleveland Clinic's Reference Range is: Less than 125 pg/mL for patients aged 0-74 years. Less than 450 pg/mL for patients aged 75-99 years.

An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat. This indication of how well your heart is pumping out blood can help to diagnose and track heart failure.

Answer From Rekha Mankad, M.D. Ejection fraction is a measurement of the percentage of blood leaving your heart each time it contracts. The heart contracts and relaxes. When your heart contracts, it ejects blood from the two pumping chambers (ventricles). When your heart relaxes, the ventricles refill with blood.

What Is a Normal Heart Rate? What's normal depends on your age and activity level, but generally a resting heart rate of 60-80 beats per minute (BPM) is considered to be in the normal range. If you are an athlete, a normal resting heart rate can be as low as 40 BPM.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.
