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.

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.
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.
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.
Close to normal, but not quite.

In atrial fibrillation (a-fib), the EKG strip will show irregular and rapid heartbeats with no distinct P waves, while a normal EKG strip will show regular and steady heartbeats with clear P waves before each QRS complex.
