Rapid Interpretation of EKG's, sixth edition, uses a programmed question-and-answer approach to introduce electrocardiography. Dale Dubin moves from cardiac electrical activity and normal waveforms to axis, chamber enlargement, rhythm disturbances, and ischemic patterns. Medical and nursing students, emergency care learners, and other clinical readers can work through concepts alongside illustrations and practice tracings.

Basic electrophysiology explains how cardiac impulses produce the waveforms seen on an EKG. The text builds from P waves, QRS complexes, T waves, and intervals to axis determination and patterns associated with atrial or ventricular enlargement. Color diagrams and short questions organize the progression into manageable steps.
Later topics include arrhythmias, conduction blocks, and changes associated with myocardial ischemia and infarction. Twelve-lead practice tracings bring these topics together for review. The programmed format lets readers check their understanding as they proceed, making the sixth edition suited to students beginning electrocardiography and clinical learners reviewing the relationship between electrical events and recorded patterns.

Inside Rapid Interpretation of EKG's, 6th Edition.
Dubin teaches electrocardiogram reading through short questions and diagrams. This guide follows his sequence from the heart's electrical events and the orientation of leads through rate, rhythm, axis, conduction, and infarction, showing how each step answers one particular question about a tracing rather than a memorized pattern.
This sixth edition is built around a programmed format: brief explanations, illustrations, and prompts that ask the reader to answer before moving on. It starts with depolarization and repolarization, then explains how leads record the same activity from different angles. Rate, rhythm, and heart block come next, followed by axis, chamber enlargement, infarction, and miscellaneous findings. Practice tracings let readers apply the full sequence. The approach rewards consistent measurement and careful description over quick pattern matching, and it stays deliberately introductory in scope.
Waves mirror electrical activity
The P wave reflects atrial depolarization, the QRS complex reflects ventricular depolarization, and the T wave largely reflects ventricular repolarization. Dubin uses these links to organize the tracing before readers assign meaning to odd shapes. Intervals are treated as durations with defined start and end points, and measurement depends on calibration and consistent boundary identification. Several clear complexes are compared before a difference is trusted.
Map each deflection to an event
Measure each interval consistently
Confirm findings across complexes
Basic Principles · p. 1
Leads are separate viewpoints
Electrodes sense potentials, while lead arrangements compare them to create directional views. Limb leads view the frontal plane and chest leads view a horizontal plane. A deflection that looks small from one angle may stand out from another. The author stresses checking labels, paper speed, and gain first, then looking for the same observation in adjacent leads and across several beats before drawing conclusions.
Know which plane a lead shows
Verify labels, speed, and gain
Check neighboring leads for support
Recording the EKG · p. 31
Rate and rhythm answer timing
Rate methods depend on whether the rhythm is regular and on the known recording speed. For irregular strips, counting events across a set time span is more dependable. Rhythm classification then combines regularity, P-wave appearance, the P-to-QRS relationship, and QRS width. The book contrasts escape beats, premature beats, and ectopic patterns so that timing and morphology are considered together.
Choose a rate approach suited to the strip
Count atrial and ventricular events separately
Combine timing with morphology
Autonomic Nervous System and Rate · pp. 55, 65; Rhythm, Part I · p. 97
Blocks change impulse transmission
Atrioventricular blocks are approached by tracking PR intervals while checking whether every atrial impulse reaches the ventricles. Some patterns show delayed conduction, others intermittent failure, and still others show atria and ventricles acting independently. Bundle branch patterns involve ventricular activation pathways, which change how long the QRS lasts and what shape it takes. The exercises train readers to describe the sequence before naming a category.
Chart P waves against QRS complexes
Distinguish delay from dropped beats
Check lead morphology for pathway clues
Rhythm, Part II: Blocks · p. 173
Axis and enlargement need context
Mean QRS axis values condense frontal-plane activation into a single direction, estimated from net deflections in limb leads and refined with an almost isoelectric lead. Chest-lead transition sits in another plane and is read separately. Enlargement patterns rely on P-wave morphology and QRS amplitude, but body build, electrode position, and conduction can all distort those signs, so the whole tracing matters.
Estimate axis from net polarity
Keep frontal and horizontal planes apart
Weigh confounders before calling enlargement
Axis and Hypertrophy · pp. 203, 243
A fixed sequence prevents misses
The infarction chapter reads Q waves, ST segment shifts, and T-wave changes across related leads, since one lead alone carries different weight than a coherent regional pattern. The final chapter adds findings that resist easy classification. Dubin's remedy is a repeatable review order covering rate, rhythm, axis, conduction, morphology, and repolarization, with clear notes on what remains uncertain.
Look for regional agreement
Note baseline and recording timing
Repeat the same review order

Key takeaways
Confirm recording speed, gain, and lead labels before trusting any measurement taken from a tracing.
Describe P-wave and QRS timing first, then move toward a rhythm or conduction label.
Check a regional finding across related leads instead of reading one lead in isolation.
