Key result
His bundle recordings reveal an unusual double ventricular response initiating PSVT in WPW syndrome.
Why the study?
An unusual mechanism in the initiation of PSVT in a patient with WPW syndrome and AV nodal conduction disturbance had not been previously reported.
Case Report (n=1)
This case report describes a novel mechanism of PSVT initiation in WPW syndrome involving a double ventricular response from a single premature atrial impulse.
No takes yet. Share an insight, caveat, or question.
Observation in one case does not change practice; leaves open prevalence of this PSVT initiation mechanism in WPW.
Takagi et al. (1978) conducted a case report in WPW (Wolff-Parkinson-White) syndrome (n=1). His bundle recordings was evaluated on Mechanism of PSVT initiation. His bundle recordings revealed an unusual mechanism of PSVT initiation in a patient with WPW syndrome, where a premature atrial impulse caused a double ventricular response.
