What is a normal QRS Duration in EKG?
0.04 - 0.12 sec (one small box - 3 small boxes)
What is a thousandth of a volt?
A milliVolt.
0.001 is this equal to one millivolt?
yes
When do you standardize an EKG?
before and after you run EKG
What is one thousandth of a Volt called?
A millivolt (mV)
What is the name of EKG tracing?
EKG stands for electrocardiogram.
How many millivolts in a volt?
that would be 1000. milli means one thousandth of the base unit (volt) millimeter is one thousandth of a meter. milliliter is one thousandth of a liter. milligram is one thousandth of a gram
What is normal gain on ekg machines?
Gain may not be exactly the right word but the standard transfer function is that 1 millivolt between electrodes causes a 10 mm deflection of the pen on the graph paper. Some machines have selectable gains, these are on top of this transfer function and are not standard nor are they usually specified in any absolute scale. They are called things like "normal" and "high" which doesn't tell you much. Amplifying a millivolt to produce a 1cm deflection is not really very hard. The hard part is digging the actual EKG signal out of all of the noise. There is sub-hz noise from patient motion, such as breathing, change of skin resistance from perspiration and/or evaporation, etc. There are myoelectric signals which are really difficult since the EKG is basically a myoelectric signal anyway. There is always a lot of line frequency (50/60 Hz) noise. Overall, bandwidth is around .05 to 150 Hz.
When will a V wave be seen on the normal EKG tracing?
Yes, a V wave will be seen on a normal EKG tracing. A V wave can signal a lot of things in an EKG, but what it means will be up to the person reading the EKG and the person's reason for the EKG.
What does ekg stand for in online ekg schools?
An ekg is a machine used in medical tests involving the heart. Often to operate one you have to attend a special school. EKG stands for: Electrocardiography.
What 1mv in decimal equation?
1 millivolt = 0.001 volt
What is the ground lead in a ekg?
When performing an EKG which limb is used as a ground.
