What are the five basic principles for understanding an EKG?

• A. Rate, rhythm, axis, hypertrophy, infarction
• B. Heart rate, blood pressure, axis, hypertrophy, infarction
• C. Rate, rhythm, pressure, hypertrophy, infarction
• D. Rate, rhythm, axis, circulation, infarction

Answer: (A)

The five basic principles for understanding an EKG—rate, rhythm, axis, hypertrophy, and infarction—provide a comprehensive framework for analyzing heart function and detecting abnormalities.

Rate refers to the number of heartbeats per minute, which is essential for assessing whether the heart is functioning within a normal range. Rhythm pertains to the pattern of heartbeats, allowing identification of irregularities such as arrhythmias. Axis helps to determine the general electrical direction of the heart, which can indicate conditions like left or right axis deviation. Hypertrophy, or the thickening of the heart muscle, can signal chronic pressure overload conditions, providing insight into the long-term health of the heart. Finally, infarction indicates areas of the heart that have suffered damage due to a lack of blood supply, which is critical for diagnosing events such as myocardial infarctions.

These principles collectively contribute to a deeper understanding of the heart’s electrical activity and overall health, making them foundational elements for anyone analyzing EKGs.
