Final answer:
A normal ECG tracing consists of the P wave, QRS complex, and T wave. The PCT should compare the current ECG to a previous one to look for changes and indications of cardiac issues. They should consider the size, duration, and vector analysis of the electrical variations to gain a comprehensive understanding of cardiac function.
Step-by-step explanation:
A normal ECG tracing consists of the P wave, QRS complex, and T wave. The P wave represents the depolarization of the atria, while the QRS complex represents the depolarization of the ventricles. The T wave represents the repolarization of the ventricles. To resolve any abnormalities or artifacts on the EKG, the PCT should compare the current ECG to a previous one to look for changes and indications of cardiac issues. They should also consider the size, duration, and vector analysis of the electrical variations to gain a comprehensive understanding of cardiac function.
