Of course it does. That is main purpose of it. It is related to the heart node electircal activity.
A low voltage EKG means the amplitude of the QRS waves on the EKG are lower than would be expected. COPD, obesity, and pericardial effusions can cause low EKG voltages, amongst other causes.
voltage
Low voltage on an EKG is usually encountered in people with very thick chest walls or with lung diseases. Low voltage results from increased impedance between the EKG leads (on the chest) and the source of the charge (the heart). Increased distance, poorly conducting tissue or air all increase the impedance, thus resulting in decreased voltage visible on the EKG.
An EKG
EKG paper is a grid where time is measured along the horizontal axis, of EKG graph paper and where to measure the components of the EKG wave form.
allows high-voltage shocks to be applied to the patient to stimulate heart action, without disconnect the EKG machine.Hope this helped! :)If you meant that the EKG registers high voltages (high R waves) and you are not referring to a "high voltage reading", if nothing else is abnormal, it could mean that the patient have a thin chest wall and pecs! Usually and echo will be done to make sure everything is okay.
a voltmeter is used to measure voltage
Any one using a voltage test instrument can measure charge differential voltage.
Many can measure both - Vrms (AC) or DC voltage.
The unit of measure for voltage is volt. Ohm measures resistance.
You measure the peak to peak voltage and divide by 2.
A voltmeter would measure the voltage. If you measure the voltage drop over a known low resistance you get a kinda-sorta idea of the power available.
