We present a case of pseudoelectrical alternans occurring during supraventricular tachycardia.
having a broad QRS complex, it is important to be able to diVerentiate between a supraventricular and a ventricular tachycardia. Medication given for the treatment of a supraventricular tachycardia (SVT) may be harmful to a patient with a ventricular tachycardia (VT). 2 A reasonable haemodynamic condition during a tachycardia may erroneously lead to the wrong diagnosis of SVT. Familiarity with ...
BACKGROUND Right ventricular pacing (RVP) during supraventricular tachycardia produces progressive QRS fusion before the QRS morphology becomes stable. This transition zone (TZ) may provide useful information for differentiating orthodromic reciprocating tachycardia (ORT) from atrioventricular nodal reentrant tachycardia and atrial tachycardia independent of entrainment success. METHODS AND R...
OBJECTIVE The purpose of this study was to determine if the atrial response upon cessation of ventricular pacing associated with 1:1 ventriculoatrial conduction during paroxysmal supraventricular tachycardia is a useful diagnostic maneuver in the electrophysiology laboratory. BACKGROUND Despite various maneuvers, it can be difficult to differentiate atrial tachycardia from other forms of paro...
