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...

This study is aimed to compare the feasibility, safety and efficacy of a zero-fluoroscopic approach using Ensite NavX with conventional fluoroscopic approach using Ensite NavX plus fluoros...
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...
To determine efficacy of bisoprolol and sotalol treatments in patients with paroxysmal supraventricular tachycardia (SVT) and essential hypertension (EH) considering effects of these treatments on the...
The use of vagal nerve stimulation is identified as a proper treatment option in patients with stable supraventricular tachycardia (SVT). This study aimed to assess the success of Valsalva maneuver vi...
The electrophysiological features and roles of persistent left superior vena cava (PLSVC) in supraventricular tachycardia (SVT) are not known.
Transesophageal echocardiography (TEE) plays a unique role in transcatheter closure of atrial septal defects (ASD) and patent foramen ovale (PFO). However, problems such as the need for general anest...
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.
Dynamic three-dimensional echocardiography using the added dimension of time to impart the cinematic perception of motion. (Mayo Clin Proc 1993;68:221-40)
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 ...
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
