What Are Those T Waves?
The patient whose ECG appears in the figure presented to an ambulatory care clinic for chest pain. Is the patient likely to have hyperkalemia?
-
Bigeminy and What Else?
The medical providers in this case were concerned the cause of the bigeminal rhythm in the figure below was sinoatrial block. Do you agree? Are there other things to be concerned about?
-
Why the Pause?
The ECG in the figure is from an older woman who complained of a number of short-lived “episodes” beginning the day this tracing was recorded.
-
What Kind of Artifact?
To emphasize the importance of recognizing the clinical finding shown in the figure, no history is given. The two most helpful leads for interpretation of these unusual ECG findings are lead I and lead V3. How would you interpret this tracing?
-
To Activate the Cath Lab?
The ECG in the figure was recorded on a patient with new chest pain that began one hour earlier. How would you interpret this ECG? Should the catheterization lab be activated, given the history and this ECG?
-
Aberrant Conduction?
How should one interpret the ECG in the figure? Is the rhythm most likely to be a re-entry supraventricular tachycardia with aberrant conduction?
-
Computer-Interpreted ECGs Sometimes Miss Acute Coronary Occlusion
Emergency physicians can shield against risk by viewing ECGs of chest pain patients immediately to identify subtle signs of acute coronary occlusion.

Is the Irregularity a Problem?
Interpreting ECGs without the benefit of any history always is challenging. Such is the case with the figure in this article, which manifests significant irregularity.
-
Syncope and Complete AV Block?
The rhythm strip shown in the figure was recorded from a patient with syncope. It was interpreted as consistent with complete AV block. Do you agree with that interpretation?

What Kind of Bundle Branch Block?
Assuming QRS widening in a supraventricular rhythm is not the result of hyperkalemia or other toxicity, and assuming the patient has not been diagnosed with Wolff-Parkinson-White syndrome, classification of 12-lead ECG conduction disturbances can be simplified into one of three basic categories. The tracing in the figure illustrates this concept.
