The prototypical ecg tracing. If a patient has a regular heart rhythm their heart rate can be calculated using the following method. An ekg uses electrodes attached to the skin to detect electric current moving through the heart.
During a single heart beat several electrical events occur. An ekg uses electrodes attached to the skin to detect electric current moving through the heart. Methods to determine heart rate the 6 second method. Calculate the heart rate measure the regularity or rhythm of the r waves examine the p waves measure the pr interval measure the qrs complex. Use this ekg interpretation cheat sheet that summarizes all heart arrhythmias in an easy to understand fashion. 5 squares 5 mv and 2 5 squares 25 mv.
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.
Methods to determine heart rate the 6 second method. 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. One of the most useful and commonly used diagnostic tools is electrocardiography ekg which measures the heart s electrical activity as waveforms. Count the number of large squares present within one r r interval. Learning the art of ecg interpretation requires intellect commitment effort and perhaps most importantly an organized approach. Take a moment to review the most common cardiac rhythms encountered in acls and pals.
