Noninvasive Diagnosis of Cardiac Arrhythmias Using Adenosine Compounds

A noninvasive imaging modality for cardiac arrhythmias.

BACKGROUND The last decade witnessed an explosion of information regarding the genetic, molecular, and mechanistic basis of heart disease. Translating this information into clinical practice requires the development of novel functional imaging modalities for diagnosis, localization, and guided intervention. A noninvasive modality for imaging cardiac arrhythmias is not yet available. Present ele...

[The use of adenosine in the diagnosis and treatment of cardiac arrhythmias].

The authors investigated the effect of adenosine or ATP on narrow QRS tachycardia in 56 pts, 3 pts with wide QRS tachycardia 9 pts with suspected latent preexcitation and 10 pts with PVC suspected to be ventricular parasystole. After the bolus iv. administration of adenosine or ATP every SVT was stopped related to AV node (44 pts), but in the rest twelve related to atrial origin of SVT only one...

Diagnosis, evaluation and treatment of cardiac arrhythmias

paediatric cardiac arrythmias commonly occur in the absence of structural heart disease, and are classified according to their cardiac site of origin. although a detailed history and examination are invaluable, a correct diagnosis cannot be made unless the eCG is analysed, taking into account features specific to this age group. a 24-hour eCG recording may also be helpful. as many of these cond...

Natural Protection Against Cardiac Arrhythmias During Hibernation: Significance of Adenosine

Noninvasive Cardiac Screening in Young Athletes With Ventricular Arrhythmias

The aim of this study was to analyze using noninvasive cardiac examinations a series of young athletes discovered to have ventricular arrhythmias (VAs) during the preparticipation screening program for competitive sports. One hundred forty-five athletes (mean age 17 ± 5 years) were evaluated. The study protocol included electrocardiography (ECG), exercise testing, 2-dimensional and Doppler echo...
