Key result
Compared to the catheterization laboratory, electrophysiological testing at the bedside resulted in a widened echo zone in 7 of 12 patients and a narrowed echo zone in 3 patients, with tachycardia only inducible at the bedside in 2 cases.
Why the study?
Does programmed stimulation at the bedside compared to the catheterization laboratory alter the echo zone and tachycardia inducibility in patients with paroxysmal supraventricular tachycardia?
Observational (n=12)
No
Does programmed stimulation at the bedside compared to the catheterization laboratory alter the echo zone and tachycardia inducibility in patients with paroxysmal supraventricular tachycardia?
Programmed stimulation at the bedside may facilitate the induction of paroxysmal supraventricular tachycardia when induction is difficult in the catheterization laboratory, likely due to differences in autonomic tone.

Sakurada et al. (1985) conducted an observational in Paroxysmal supraventricular tachycardia (PSVT) (n=12). Electrophysiological testing at the general ward (bedside) vs. Electrophysiological testing at the catheterization laboratory was evaluated on Change in echo zone (EZ) of paroxysmal supraventricular tachycardia. Compared to the catheterization laboratory, electrophysiological testing at the bedside resulted in a widened echo zone in 7 of 12 patients and a narrowed echo zone in 3 patients, with tachycardia only inducible at the bedside in 2 cases.
