Question: 1 / 400

What is the purpose of using a 15-lead ECG instead of a standard 12-lead?

To reduce the number of electrodes used

To provide a more comprehensive view of the heart's electrical activity

The purpose of using a 15-lead ECG instead of a standard 12-lead is to provide a more comprehensive view of the heart's electrical activity. The additional leads in a 15-lead ECG allow for enhanced visualization of specific areas of the heart, particularly in situations where there may be suspicion of issues in regions not fully captured by the standard 12-lead configuration. For example, the additional leads can better assess changes in the right side of the heart and provide insight into conditions such as right ventricular hypertrophy or certain types of ischemia that may not be as evident with only the standard leads. This comprehensive analysis can lead to improved diagnosis and management of cardiac conditions, enhancing patient care.
