Table 2
Indications and results of EPS.
Arrhythmia/symptoms (number of patients)
EPS/ablation successful (number of patients)
EPS/ablation not successful (number of patients)
Reason/comment (number of patients)
Atrial flutter ()
12
2
Successful ablation in 12 patients. Placement of catheter not successful (), third degree heart block ().
Atrial tachycardia ()
2
9
Successful ablation in 2 patients. Multifocal tachycardia and ablation are not feasible (), placement of catheter is not successful (), no entrainment (), origin at atrial septum without is ablation procedure ().
Atrial fibrillation

—
Successful ablation in 1 patient.
Incisional reentry tachycardia ()
2
—
Successful ablation in 2 patients.
AVNRT ()
4
—
Successful ablation in 4 patients.
Nonsustained VT ()
15
—
No induction of VT.
Monomorphic premature ventricular beats ()
3
1
Successful ablation in 2 patients (right ventricle outflow tract). In 1 patient multiple foci (origin in left and right heart), ablation is not feasible.
Slow VT ()
2
