An electrocardiogram (ECG) is a test that measures the electrical activity of the heart. It’s used to detect heart conditions and problems with the heart’s electrical conduction system. An ECG usually shows the rate and regularity of the heartbeat and the size and position of the heart chambers. The test can also show evidence of heart damage and problems with the heart’s electrical conduction system.
To find the atrial rate on an ECG look for the P wave. The P wave is the first positive deflection after the QRS complex. The atrial rate is usually the same as the sinus rate. Answer to question 15:
