Know how to measure the PR interval ( PRI) - From where the P wave begins until the beginning of the QRS complex. 0.12 to 0.20 seconds (3 to 5 small boxes) in adults, longer in elderly people. Know how to measure the QRS - From the end of the PR interval to the end of the S wave. 0.08 to 0.10 seconds. (2-2 1/2 boxes) Know the normal values for the PRI 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. An EKG uses electrodes attached to the skin to detect electric current moving through the heart. These signals are transmitted to produce a record of cardiac activity. Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occurs as a result of alterations within the conduction of electrical imp...

You are the nurse working on the telemetry unit and you have finally gotten to sit down to work on some charting. Suddenly the heart monitors at the station start beeping. Patient in room 18 is showing this rhythm on the monitor. The medical team advances together into the room and finds them unconscious. What is priority action by the nurse? A) Prepare to administer adenosine to the patient B) Begin chest compressions C) Prepare for defibrillation D) Check for a pulse Answer: D A pulse w...
