Some information found in a 12-lead electrocardiogram interpretation includes the number of beats per minute, the regularity of the heart's rhythm and whether the wave tracings appear normal, according to WebMD. A 12-lead EKG, or ECG, is the standard type of electrocardiogram and is used to measure the heart's electrical activity, notes the University of Utah's ECG Learning Center.Continue Reading
The 12-lead EKG reads the heart's electrical activity as a series of spikes and dips. A physician, such as a cardiologist, interprets these waves to determine if there are any issues with the heart. An EKG has a normal interpretation if the tracing looks normal, with no odd dips or spikes, and the heart beats at a regular rhythm, states WebMD. A normal heart typically beats between 60 and 100 times per minute, which is shown on the EKG.
An abnormal EKG interpretation occurs if the heart is beating less than 60 beats per minute or more than 100 beats per minute. It is also abnormal if the tracings show abnormalities or if the heart's rhythm is not regular, notes WebMD. An abnormal EKG can help determine the cause of a variety of heart-related symptoms, such as chest pain, shortness of breath, fainting or irregular heartbeats, according to Johns Hopkins School of Medicine.Learn more about Diagnostics & Imaging
