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.

What do doctors use graphs for?
EKG
What the straight line on the EKG is called?
The straight line on an EKG is called the isoelectric line. It represents the baseline electrical activity of the heart when there is no depolarization or repolarization occurring. Deviations from this line indicate electrical activity associated with heartbeats, such as P waves, QRS complexes, and T waves.
The vertical axis of the ecg paper measures?
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.
What do the horizontal lines on an ekg measure?
The horizontal axis is time. The vertical axis is a measure of something electrical (the wires are connected to electrical contacts on your chest).
How do you calculate the gain speed on the ekg?
To calculate the gain speed on an EKG, you typically assess the amplitude of the QRS complex or other waves by measuring the vertical height (in millimeters) of the waveform on the graph paper. Each small box on standard EKG paper represents 0.1 mV vertically, so if a QRS complex measures 10 mm in height, it corresponds to 1 mV. The gain speed can be adjusted on the EKG machine, often set at 10 mm/mV, but if the gain is altered, you must account for this when interpreting wave amplitudes. Always refer to the specific settings on the EKG machine for accurate calculations.
What does the Ventrical lines on EKG paper represent?
voltage
What does an electrocardiogram (EKG) measure in the human body?
An electrocardiogram (EKG) measures the electrical activity of the heart in the human body.
What do you use to measure a heart rate of a person?
An EKG
Which of the following procedures is abbreviated as either ECG or EKG?
An abbreviation for ElectroCardiogram: A procedure in which electrodes placed on the chest wall pick up the electrical conduction/activity of the heart. The depolarization and repolarization of the cardiac miocytes are are transcribed on a sheet of paper with the amplitude (+ or -) on the X axis, and time on the Y axis.
What is the speed of the ekg paper?
25 mm/sec
Does EKG measure voltage?
Of course it does. That is main purpose of it. It is related to the heart node electircal activity.
When do you standardize an EKG?
before and after you run EKG
How do EKG machine leads work?
EKG machine leads are electrodes attached to the patient's skin to measure the electrical signals produced by the heart. The leads pick up these signals and transmit them to the EKG machine, which then displays them as a graph that represents the heart's electrical activity. Different lead placements provide different views of the heart's electrical activity.
What is the name of EKG tracing?
EKG stands for electrocardiogram.
