ECG ECG measures electrical activity of heart composite record of hearts electrical events during a cardiac cycle requires proper electrode placement can monitor HR what to look for on ECG rate rhythm always want P and QRS PR interval shape of QRS P wave atrial depolariza

To determine whether there is a delay in impulse conduction through the ventricles, the nurse will measure the duration of the patient's a. P wave. c. PR interval. b. Q wave. d. QRS complex. - -ANS: D The QRS complex represents ventricular depolarization. The P wave represents the depolarization of the atria. The PR interval represents depolarization of the atria, atrioventricular node, a bundle of His, bundle branches, and the Purkinje fibers. The Q wave is the first negative deflection fol...

what is Shortened PR interval Solution PR interval is the duration from the begning of P wave and at the bigning of QRS complex in electrocardiography which is measured in milliseconds. The Shortened PR interval is the duration less than 120ms associated with Lown Ganong Levine Syndrome and Wolff Parkinson White Syndrome. The normal PR interval duration is range in between 120ms to 200ms sometimes also known as normal PQ interval.
