what is a average ECG signal size?

a few millivolts on the order of 60-120 Hz, depending on your heart rate.

This sounds like Unstable Angina.  A normal heart rate can range between 50 and 80 beats per minute. The best way to take your pulse is to take your pointer finger and place it on the side of your neck. Relax and gently poke around until you feel the pukse. Count the number of beats for 30 seconds and multiply by two. This is your heart rate.  If you have pain in the chest or radiating down your arm, or if you feel as if someone is squeezing your chest and you can't breathe, you may be having a heart attack. Call 911 or have someone bring you to the nearest hospital for evaluation.

Resting Heart rate\nThe best time to find out your resting heart rate is in the morning, after a good night's sleep, and before you get out of bed.\n\nThe heart beats about 60 to 80 times a minute when we're at rest. Resting heart rate usually rises with age, and it's generally lower in physically fit people. Resting heart rate is used to determine one's training target heart rate. Athletes sometimes measure their resting heart rate as one way to find out if they're overtrained. The heart rate adapts to changes in the body's need for oxygen, such as during exercise or sleep.

end diastolic volume is typically 120mL/beat and end systolic volume is aproximately 50mL/beat

98.6 is a normal AVERAGE, what ever you usually run is normal for you...if you are concerned talk to your doctor

Treadmill stress electrocardiography is employed widely to detect underlying cardiovascular disease in asymptomatic persons. To determine the frequency and significance of an abnormal S-T segment response to exercise in young athletes with increased left ventricular (LV) mass induced by physical conditioning, 75 male isometrically trained athletes without evidence of heart disease (mean age 21 years) and 48 nonathletic young normal subjects were studied by M-mode echocardiography and exercise electrocardiography. Ventricular septal and posterior free wall thicknesses and calculated LV mass were significantly greater in athletes than in control subjects. An abnormal S-T segment response to exercise was present in 7 (9%) of the 75 athletes, all of whom had a LV mass greater than 275 g and in 5 the LV mass was above the 95th percentile of that of the control subjects. An abnormal treadmill exercise test result also was present in 3 (6%) of 48 control subjects. Seven of the 10 subjects with abnormal exercise test results had radionuclide angiograms at rest and with exercise, each of which was normal. It is concluded, therefore, that (1) abnormal exercise test results occur commonly in both athletes and non-athletes; (2) almost 10% of isometrically trained athletes have "false-positive" exercise electrocardiograms, suggesting that this test has major limitations in screening for underlying cardiovascular disease in athletes; and (3) in athletes, a relation was present between "physiologically" increased LV mass and false-positive exercise test results.

No. Depending on your age, a normal RESTING heart rate is between 60 and 80 beats per minute. 114 is fine if you were just exercising. But if that is your resting heart rate, I would suggest talking to a doctor.

www.ecglibrary.com hass all kinds of information\n\n-or try searching for ECG or EKG interpretation with any internet search engine, there is a plethora of resources out there\n\n-or go to a library (especially if you have access to a univeristy or medical school library) and find any of a thousand books on the subject

Wolff Parkinson White syndrome is a specific diagnosis that can only be made on an electrocardiogram.\n\nSpecifically on the ECG, a person with WPW has a shortened PR interval and delta upslurring of the QRS complex.\n\nIt usually doesn't mean a great deal but if you have WPW you are at risk of something called a re-entrant phenomenon where your pattern of heart beat becomes abnormally fast, which is dangerous.\n\nYou probably should see your doctor for more advice if you've been told to have this problem.

PR Interval. The interval between atrial contraction and ventricular contraction. It should be between 0.16 and 0.2 seconds.\n\nQRS Complex. The 'squiggle' that denotes the electrical changes of ventricular contraction. It should be narrow, not broad, it should be of a normal shape\n\nQT Interval. The interval between depolorisation of the the ventricles and repolorisation of the ventricles. It should be between 0.3 and 0.44 seconds. QTc is the QT interval corrected for heart rate, it's not normally used all that much.\n\nTry looking at;\nhttp://www.ecglibrary.com/

It is hard to understand an EKG (a series of lines sent by the electrisity in the heart) unless you are trained. The doctor explained it and you are verry lucky to be getting in to see a cardiologist in a week (it can take a month depending on where you live) The cardiologist will probably do another one and can explain it more, you would need to go through a lot of training or see a doctor to get another explaination or information.

The normal resting heartbeat range is from 60 to 100.

60-80 beats per minute is considered a normal heart rate.

I am not sure what you are asking but I am guessins on an ECG. Compressed T wave is probably an abnormal T-wave in the ECG, usually smaller than a normal rythm

The EKG estimates the net vector (in two dimensions) of the electrical activity of the heart; from the direction that the V1 lead looks (Above and to the right of the heart, as I recall laying out the electrodes years ago), the electrical activity is going away from the lead--towards the feet, or in the QRS part (the really big deflection), it's going from the AV node toward the tip of the ventricles.  That would be read as a negative direction.\n\nRemember, at every instant in time, the EKG is recording the equivalent of the dot product between the actual vector of the flow of current (so to speak) in the heart, and a vector that is created by connecting the leads in question.  For the V1 lead (a precordial lead), the leads connected to the limbs are used as a single lead, sort of grounding things out between all four of them (think of it being a lead somewhere behind the belly button, if you want), and then measuring the dot product of the electrical vector and a line connecting the V1 position with that.\n\nA little vector algebra makes this a LOT easier!

With the average heart rate of 72 beats per minute the heart will pump about 5 litres per ventricle, or about 10 litres total per minute. This is called the cardiac output. In a trained athlete the total cardiac output is about 20 litres. If we multiply the normal, non-athlete output by the average age of 70 years, we see that the cardiac output of the average human heart over a life time would be about 1 million litres, or about 250,000 gallons(US)!
