Frequencies and types of arrhythmias in patients with systemic light-chain amyloidosis with cardiac involvement undergoing stem cell transplantation on telemetry monitoring.

29 Sep 2009 Cardiac patients with systemic light-chain amyloidosis have a high incidence of arrhythmias and arrhythmia-related death. We aimed to describe the arrhythmias, determine patient characteristics associated with the development of ventricular ... Read more...

[Intraoperative ventricular or supraventricular tachycardia? A case report]

30 Aug 2009 A 68-year-old man with a history of paroxysmal supraventricular tachycardia developed wide QRS complex tachycardia one minute after induction of general anesthesia. As the wide QRS complex tachycardia appeared to be ventricular and pulsation of the ... Read more...

A nonsense SCN5A mutation associated with Brugada-type electrocardiogram and intraventricular conduction defects.

30 Aug 2009 Mutations of SCN5A, gene-encoding alpha-subunit of cardiac sodium channel, can cause mixed phenotypes of Brugada syndrome (BrS) and cardiac conduction diseases (CCD). We have identified a nucleotide change of SCN5A (4178T > G), which results in a ... Read more...

Technical information about 'Tachycardia, Ventricular'

Definition: An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
