Atrial standstill in a pediatric patient with associated caveolin-3 mutation
Introduction Atrial standstill (AS), a rare arrhythmogenic condition, is defined by (1) the absence of P waves in surface and intracavitary electrocardiograms (ECGs), (2) the absence of A waves in jugular venous pulse and right atrial pressure tracings, (3) the presence of a supraventricular type QRS complex, (4) the immobility of the atria on fluoroscopy, and (5) the inability to stimulate the...
متن کاملCongenital atrial standstill associated with coinheritance of a novel SCN5A mutation and connexin 40 polymorphisms.
BACKGROUND Congenital atrial standstill has been linked to SCN5A. Incomplete penetrance observed in atrial standstill has been attributed in part to the digenic inheritance of polymorphisms in the atrial-specific gap junction connexin 40 (Cx40) in conjunction with an SCN5A mutation. OBJECTIVES The purpose of this study was to determine the clinical and biophysical characteristics of a novel S...
متن کاملImplantable Cardioverter-Defibrillator Implantation in a Patient with Atrial Standstill
We report a 55-year-old female patient who presented with no P waves but with a wide QRS complex escape rhythm at 44 beats/min and prolonged QTc of 0.55 seconds on ECG. The patient had recurrence of ventricular fibrillations and loss of consciousness, and underwent defibrillation and cardiopulmonary resuscitation (CPR) several times because of cardiac arrest. The transthoracic echocardiography ...
متن کاملTemporary atrial standstill in a crossbred dog associated with bladder outlet obstruction
A 6-year-old male crossbred dog was referred to the Veterinary Medical Teaching Hospital of Islamic Azad University of Karaj with the history of abdominal distention, rectal tenesmus and stranguria. Abdominal radiographs and ultrasonography indicated large distended urinary bladder and prostatic enlargement. ECG showed temporary episodes of atrial standstill. The only abnormalities detected by ...
متن کاملA cardiac sodium channel mutation cosegregates with a rare connexin40 genotype in familial atrial standstill.
Atrial standstill (AS) is a rare arrhythmia that occasionally appears to be genetically determined. This study investigates the genetic background of this arrhythmogenic disorder in a large family. Forty-four family members were clinically evaluated. One deceased and three living relatives were unambiguously affected by AS. All other relatives appeared unaffected. Candidate gene screening revea...
