Calculating the heart rate is easy because the EKG is always recorded on graph paper that measures time as it travels horizontally through the machine. Ignoring the heart rate on an EKG is the single most common mistake in learning to read an EKG! 1 33 34 Chapter 4 Measurement of the Heart Rate The most accurate way to measure heart rate is by measuring the R-R interval. The R-R interval is the distance from one R wave to the next R wave. When measuring the R-R interval, take the beginning of one QRS complex, and count the number of “little boxes” up to the beginning of the next QRS complex.
Basics of the 12-Lead EKG 3 Self-Study Objectives ■ Identify and describe the following: Five critical electrical and mechanical functions The heart has an intricate electrical system, made up of highly specialized cells, that is responsible for generating each heart beat. The specialized cells are responsible for ﬁve critical electrical and mechanical functions: (1) establishing the ability to create an automatic and regular heart rhythm; (2) allowing communication among the billions of cells in less than one-tenth or two-tenths of a second; (3) providing for activation of the myocardial cells; (4) triggering mechanical contraction; and (5) resetting the system for the next cycle in a process called repolarization.
12 44 Instructions for Chapter 4 Worksheets Clinically Based Critical Thinking: Interpretation A) Count the number of small boxes between two QRS complexes. Divide that number into 1500 to accurately determine the HR. B) Use the heart rate to classify the rhythm as sinus rhythm (60 to 100), sinus tachycardia (greater than 100), or sinus bradycardia (less than 60). C) Provide an interpretation Sinus tachycardia should always be evaluated and explained clinically. It is a vital sign, and always has clinical relevance.
