Electrocardiograms Recorded After Asystolic Cardiac Arrest.

A man with a history of drug abuse was found down at home and was asystolic. Following restoration of sinus rhythm, a hypothermia protocol brought his temperature to 32.5°C (90.

Type I Second Degree Atrioventricular Block in a Woman With Remote Repair of a Ventricular Septal Defect.

In a 45-year-old woman with syncope, an electrocardiogram revealed intermittent asymptomatic type I second degree atrioventricular block, right bundle branch block and left anterior fascicular block. An echocardiogram documented concentric left ventricular hypertrophy and right ventricular dilatation and hypokinesia. Because the patient did not have second degree atrioventricular block at the time of an electrophysiological study, the atrioventricular node, the left posterior fascicle, and the His bundle all remain potential sites for the type I second degree atrioventricular block on her initial electrocardiogram.

ECG Case of the Month: Wide-QRS Rhythm in a Man with a Clotted Dialysis Fistula.

A 57-year-old man with diabetes mellitus, systemic arterial hypertension, and end-stage kidney disease came to the hospital because his arteriovenous fistula used for hemodialysis had clotted. His blood hemoglobin level was 12.8 g/dL (reference, 13.

Lower Extremity Paralysis.

Severe hypokalemia in the absence of other electrolyte abnormalities, the result of diarrhea, caused striking electrocardiographic changes, generalized weakness, flaccid paralysis of the lower extremities, and biochemical evidence of mild skeletal and cardiac rhabdomyolysis in a 33-year-old man. Repletion of potassium reversed all abnormalities in 24 hours.

Clinical case of the month. A 29-year-old man with acute onset blurry vision, weakness, and gait abnormality. Stroke.

A 29-year-old man, with no significant past medical history, was in his usual state of health until the afternoon of admission. The patient was seated at work eating lunch when he suddenly noticed that his vision became blurry. He covered his right eye and had no visual difficulty but noted blurry vision upon covering his left eye.

Management of acute ST-segment elevation myocardial infarction. II. Beyond reperfusion.

The last issue of the Journal contains a continuing medical education article on reperfusion therapy in acute ST-segment elevation myocardial infarction (STEMI), and this article completes the sequence by discussing other aspects of the management of acute STEMI.
