The basic components of an electrocardiograph are : Electrodes, Leads, the galvanometer, the amplifier and the stylus. The heated stylus records the motion on graph paper located in the machine by burning the impression on the heat-sensitive paper.
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.
voltage
25 mm/sec
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.
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.
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
The normal running speed on EKG paper is typically 25 mm per second. This means that each small square on the EKG paper represents 0.04 seconds, while each large square (composed of five small squares) represents 0.20 seconds. This standard speed allows for accurate measurement of heart rhythms and intervals. Adjustments to the speed may be made in specific clinical situations, but 25 mm/sec is the most common setting.
before and after you run EKG
EKG stands for electrocardiogram.
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.
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.
