Shortening of the Short Refractory Periods in Short QT Syndrome [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundDiagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown ...

Left Ventricular Outflow Tract Tachycardias

Indian Pacing and Electrophysiology Journal, 2013
Left ventricular outflow tract tachycardia (LVOT-VT) is an uncommon type of idiopathic left ventricular tachycardia (ILVT) thought to be due to cyclic adenosine mono phosphate (c-AMP) mediated triggered activity. The arrhythmia can be terminated pharmacologically with calcium channel blockers or beta-blockers.

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia [PDF]

Indian Pacing and Electrophysiology Journal, 2005
Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.

A single coronary artery with left circumflex artery crossing right ventricular outflow tract in tetralogy of Fallot with absent left pulmonary artery [PDF]

Journal of Cardiovascular and Thoracic Research, 2021
Tetralogy of Fallot (TOF) with unilateral absence of pulmonary artery and the anomalous coronary artery is a rare combination. Detailed preoperative evaluation of coronary artery anatomy is must to prevent injury to the major vessels crossing right ...

Left Ventricular Outflow Tract Myxoma [PDF]

European Journal of Echocardiography, 2003
This article reports a left ventricular outflow tract (LVOT) myxoma, presenting with peripheral embolus, in a 90-year-old patient during the follow-up due to ischemic heart disease. Among LVOT myxomas, which are usually very rare and most likely to present with manifestations due to obstruction, this is the first case presenting with peripheral embolus.
