PPT-Life T hreatening Arrhythmia

VENTRICULAR TACHYCARDIA Ventricular tachycardia can be caused by disorders of impulse formation enhanced automaticity or triggered activity and conduction reentry In general the specific type prognosis and management of VT depend on the presence of .

M.V.Jorat. MD. 1389. Definition. Narrow QRS complex supraventricular tachycardia (SVT) is a tachyarrhythmia with a rate more than 100 beats/min and a QRS duration of less than 120 milliseconds.. A narrow QRS complex (<120 msec) reflects rapid activation of the ventricles via the normal His-Purkinje system, which in turn suggests that the arrhythmia originates above or within the atrioventricular (AV) node (ie, a supraventricular tachycardia). . contents.

Presentation: Sedona had not eaten for 3 days and had 15 episodes of shaking/collapsing in the last day. During these episodes, there was no salivation or chomping. Her front legs became rigid, and she fell over with eyes dilated. She returned to normal within 10 minutes following each episode. .
