Unraveling arrhythmogenesis in cardiac surgery

Aims of this thesis were to examine:
1. The incidence and time course of non-sustained and sustained ventricular tachyarrhythmia in the early postoperative phase after coronary artery bypass grafting surgery.
2. The time course and coexistence of various tachyarrhythmia in patients with congenital heart disease and, particularly, in patients with tetralogy of Fallot, and their influence on survival.
3. The early and late surgical outcome of patients with tetralogy of Fallot in current clinical practice.
4. The outcome of surgical ablation for atrial fibrillation in patients with congenital heart disease.
5. The physiological conduction and electrophysiological characteristics of the right and left atrium.
6. Whether underlying heart diseases lead to alterations in atrial excitation associated with development of atrial fibrillation.
7. The variation in physiological conduction at the left atrial posterior and inferior wall and its association with atrial fibrillation.
