This study will evaluate the efficacy of the Foresight Intracardiac Echocardiography system ,with improved image quality, in guiding trans-septal punctures during atrial fibrillation ablat...
• Supraventricular tachycardia (SVT) is defined as an abnormally rapid heart rhythm originating above the ventricles. It usually has narrow complex tachycardia but this is not always the...

Intranasal dexmedetomidine administered as premedication before anesthesia and cardioversion appears to have the potential to facilitate the return of sinus rhythm. Two children, 3.5 and 1.5 years old...
Currently, there is no accepted protocol for left atrial appendage (LAA) imaging with intracardiac echocardiography (ICE).
The electrophysiological features and roles of persistent left superior vena cava (PLSVC) in supraventricular tachycardia (SVT) are not known.
A generic expression for any tachycardia that originates above the BUNDLE OF HIS.
A rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the ATRIOVENTRICULAR NODE. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a HEART RATE ranging from 140 to 250 beats per minute.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
