Name: Pacing and clinical electrophysiology : PACE
A 47 year old lady presented with recurrent episodes of palpitation. During one of the episodes a wide QRS tachycardia with left bundle branch block (LBBB) morphology was recorded that was reported to...
BACKGROUND Response to cardiac resynchronization therapy (CRT) is variable among patients. Extensive scar tissue burden has been characterized as a negative predictor of significant response. Whereas ...
The LEVEL-AT Trial (LEft VEntricuLar Activation Time Shortening with Hisian Pacing vs Biventricular Resinchronization therapy: a randomized study) is a non-inferiority study that aims to d...
The purpose of this study is to determine, using echocardiography, whether bi-ventricular pacing improves the contractile force by resynchronizing both ventricles, thereby improving and/or...
The SYNSEQ study intends to assess the positive left ventricular dP/dt max achieved by multipoint LV pacing (either simultaneously or sequentially) in comparison to the response achieved b...
The purpose of this study is to evaluate the effects of multisite left ventricular (LV) biventricular (BiV) pacing on LV hemodynamics in CRT patients. It is hypothesized that the effect of...
Optimal pacing strategy for patients with SND is still unknown, although several publications in the past years demonstrated a deleterious effect of ventricular pacing. However, pacing has...
Moving oneself through space while confused or otherwise cognitively impaired. Patterns include akathisia, exhibiting neuroleptic-induced pacing and restlessness; exit seekers who are often newly admitted institution residents who try to open locked exit doors; self-stimulators who perform other activities such as turning doorknobs, in addition to continuous pacing; and modelers who shadow other pacers.
Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.
The restoration of the sequential order of contraction and relaxation of the HEART ATRIA and HEART VENTRICLES by atrio-biventricular pacing.
