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.

How Many Abnormal Findings?
No history was available for the tracing in the figure. There are at least seven ECG findings to note. How many can you identify?
-
A Hidden Rhythm
The only clinical information available for this tracing is that the ECG was obtained from an older woman. Without any other background, where should we go from here?

Med/Mal Claims Focus on Decision Aid Findings from ECGs, Radiology Tests
If the radiologist does not address computer findings directly, the ED clinician is left to make assumptions about what the radiologist has found significant or insignificant. If radiologists are not routinely addressing computer findings, emergency providers will spend resources attempting to sift through reports and images, trying to rule in or out what the computer has found. Radiologists should acknowledge computer findings, and comment on why or why not the finding is accurate and significant to the patient’s care.

Stroke and a Wide QRS
The ECG in the figure is from an older man who presented with an acute stroke. He denied chest pain. Why is there QRS widening? What might be the clinical implications?

Unexpected Low Voltage on an ECG
A registry study of hypertrophic cardiomyopathy (HCM) patients and elite athletes in Italy revealed low voltage on ECG is not uncommon in HCM and may be a marker for more left ventricular scarring on cardiac imaging — and a poor prognosis.
-
Double BBB, or Complete AV Block?
The ECG in the figure is from a woman who complained she had been experiencing chest pain for several days. What is the rhythm? Is there complete AV block?
