Problem
• What is the rate? Is it within the normal range of 60-100 beats per minute?
• Is the rate fast, normal, slow, or very irregular?
• Are all normal waves present in recognizable form?
• What is the QRS shape? Is the QRS complex extended?
• Does all of the QRS complexes look the same?
• Does all the P waves look the same?
• Is there one QRS complex for each P wave?
• If yes, is the P-R segment constant in length?
• If there is not one QRS complex for each P wave, count the heart rate using the P waves, then count it according to the R waves. Are the rates the same? Which wave would agree with the pulse felt at the wrist?
