The electrocardiogram in pericarditis

The American Journal of Cardiology, 1961
HE ELECTROCARDIOGRAM is abnormal in many, perhaps in most, cases of clinically significant pericardial disease . Frequently the electrocardiographic abnormalities are characteristic of or strongly suggestive of pericarditis, but only rarely, if ever, are they in themselves diagnostic .

The electrocardiogram in obesity

Journal of Electrocardiology, 1982
The electrocardiographic abnormalities ascribed to morbid obesity were analyzed in a group of 144 patients without apparent clinical cardiovascular pathology and compared with a control group of 100 normal weight patients. Fifty-eight patients in the obese group were re-analyzed after significant weight loss and the electrocardiographic findings ...

Electrocardiogram in Pneumonia

The American Journal of Cardiology, 2012
Findings on electrocardiogram may hint that pulmonary embolism (PE) is present when interpreted in the proper context and lead to definitive imaging tests. However, it would be useful to know if electrocardiographic (ECG) abnormalities also occur in patients with pneumonia and whether these are similar to ECG changes with PE.

Clatter on the electrocardiogram

Journal of Electrocardiology, 2013
An ECG recorded from a patient with an implanted cardiac pacemaker showed a striking high frequency pulsing on the ST-T segments linked with each QRS complex. In this report we present an approach to the clatter on the ECG and discuss various potential diagnoses that can have closely similar pattern.

The aging electrocardiogram

The American Journal of Emergency Medicine, 1990
With advancing age, widespread histologic changes in the conduction system occur. These changes may alter several features of the aging electrocardiogram, including duration of the PR and QT intervals, orientation of the electrical axis, duration and morphology of the atrial and ventricular complexes, and characteristics of the ventricular ...

The electrocardiogram of burros

Journal of Electrocardiology, 1975
Electrocardiograms of two burros are presented. Compared to those seen in humans, amplitudes were lower, especially in lead I, and marked prolongations were observed in P-Q and Q-T intervals. The QRS axes were craniad.

The Electrocardiogram and the Athlete

Sports Medicine, 1984
Physiological adaptations of the heart to prolonged, intense physical training produce electrocardiographic changes considered abnormal in untrained persons. Increased vagal tone, anatomical changes in the heart, and other less understood mechanisms are thought to cause a spectrum of surface ECG changes characteristic of trained athletes.

The athlete's electrocardiogram

The American Journal of Emergency Medicine, 2006
The electrocardiogram performed in the competitive athlete may manifest abnormal electrocardiographic findings; these findings may indicate either normal variant syndromes as well as true cardiac pathology. The normal variant syndromes include ST-segment and T-wave abnormalities, rhythm disturbances, and intraventricular conduction delay--it must be ...
