Of course it does. That is main purpose of it. It is related to the heart node electircal activity.
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.
Low voltage on an EKG typically indicates a decrease in the electrical activity recorded from the heart, which can be caused by a variety of factors such as obesity, chronic lung disease, pericardial effusion, or poor contact between the skin and EKG electrodes. It is important to follow up with a healthcare provider to determine the underlying cause and appropriate management.
The vertical axis of the EKG paper measures the amplitude or voltage of the electrical signals generated by the heart. This is typically expressed in millivolts (mV), with each small square representing 0.1 mV. The height of the deflections in the EKG waveform indicates the strength of the electrical activity occurring during each heartbeat.
An electrocardiogram (EKG) measures the electrical activity of the heart in the human body.
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
Many can measure both - Vrms (AC) or DC voltage.
Any one using a voltage test instrument can measure charge differential voltage.
The unit of measure for voltage is volt. Ohm measures resistance.
