How To Interpret Ekg Rhythms. A detailed guide to interpreting the most common ekg heart rhythms for nurses and health care professionals. Count the number of large squares present within one r r interval. How to interpret an ecg. Say for example in the image below there are 5 boxes between the 2 r s.
Count the number of large squares present within one r r interval. How to interpret an ecg. A normal heart rhythm contains a p wave a qrs and a t wave knowing the normal amplitude deflection and duration of each component is essential to accurate rhythm and ekg interpretation. Regular heart rhythm if a patient has a regular heart rhythm their heart rate can be calculated using the following method. This measures the voltage of the beat and is determined by how high the wave reaches as measured by each square vertically on the chart. 5 squares 5 mv and 2 5 squares 25 mv.
You can then see the time between your heartbeats which should be 12 20 seconds in 3 5 small horizontal boxes.
An ekg uses electrodes attached to the skin to detect electric current moving through the heart. Hence 300 4 will yield 75 thus 75bpm. This measures the voltage of the beat and is determined by how high the wave reaches as measured by each square vertically on the chart. Rather these steps simplify the approach to reading and interpretation of an ecg in clinical practice. Additionally identify the squares that measure time along the horizontal axis. Say for example in the image below there are 5 boxes between the 2 r s.
