Transient electrocardiographic changes following smoking cannabis

Transient electrocardiographic changes during two episodes of relapsing brucellosis.

Cardiac involvement in the course of acute brucellosis is rare and, when present, is usually manifested by endocarditis. Myocarditis is very infrequent and in the few reported cases, the course of the disease was fulminant. A patient with recurrent brucellosis who presented transient electrocardiographic T wave changes during two episodes of acute illness is reported. It is suggested that the p...

Electrocardiographic Changes Associated with Smoking and Smoking Cessation: Outcomes from a Randomized Controlled Trial

INTRODUCTION Cardiovascular disease (CVD) can be detected and quantified by analysis of the electrocardiogram (ECG); however the effects of smoking and smoking cessation on the ECG have not been characterized. METHODS Standard 12-lead ECGs were performed at baseline and 3 years after subjects enrolled in a prospective, randomized, placebo-controlled clinical trial of smoking cessation pharmac...

Electrocardiographic changes in atrial septal defect following surgical correction.

The electrocardiogram in atrial septal defect is of great value, not only in the diagnosis but also in the assessment of the severity of the lesion. The pattern that has been designated "incomplete right bundle-branch block," though not present in every case nor by any means pathognomonic of the condition, is nevertheless frequently noted. Before describing the changes in the electrocardiogram ...
