What Does Pvb Of The Heart Mean
Ejection fraction: Ejection fraction is a method of measuring how well the heart squeezes. Normal should be around 65%. It is the percentage of blood a full heart pushes out with heart beat. So if a full heart had 100ml of blood then with an ef of 45%, 45ml of blood would be ejected with a heart beat. ...Read more
Palpitation Sx: Palpitations are an awareness of extra heartbeats which most of us have. The sensation can be single or multiple and can sometimes last minutes. Different people may feel other symptoms along with them such as dizzy, lightheaded or short of breath. The palpitations are almost always atrial or ventricular premature beats. Usually benign but they are also found with abnormal hearts. ...Read more
Tachycardia: Most resting heart rate normals are 80 to 100 bpm. Some people's resting heart rate is higher. Abnormal reasons for higher resting heart rate include anemia, hyperthyroidism, fever, ongoing inflammation or infection, dehydration and there is also a pathologic sinus tachycardia condition. You'd need to see a dr. And be evaluated if you're worried about your resting heart rate. ...Read more
EF 44%.: I assume you mean EF ( Ejection Fraction ) is 44%. The EF is a measure of how much blood was in the main pump of the heart at the beginning of contraction as compared to the end of contraction. This is not the same as function at all. Having said that >55% is "normal." 13% of people age 50-70 have EF ...Read more
Get an echo: Upper normal limit is not normal and not common in a 27 year old, but, if it's based on a chest x-ray, it's not reliable. Ask your doctor for an echo. (comment: if you failed to take a really good deep breath at the moment they took your chest x-ray, it will falsely make your heart appear to be larger than it really is). ...Read more
Palpitations: Palpitations have many causes from anxiety through anatomic and physiologic abnormalities. The feeling of bounding usually relates to the volume of blood pumped with each palpitation. There is no simple single answer for the question. If you're bothered by the feeling should consult a dr. To see if the problem can be clarified. ...Read more
QT: I think you mean qt since there is no qi. This is a measurement (in milliseconds) obtained on ekg of the time it takes for the ventricles to electrically prepare for their next contraction. Sodium, potassium, and calcium ions move through channels during this period. Some drugs and some families have abnormalities of this movement which can lead to characteristic rhythm problems. ...Read more
