• Supernormal conduction
• Atrial premature beat
• Linking phenomenon
• Bundle branch block

Supernormal conduction is defined as better-than-expected conduction in patients with depressed conduction during a short interval in the ventricular cycle. It is mainly observed in long-duration electrocardiogram (ECG) assessments. Its occurrence during 12-lead ECG is uncommon and its interpretation demands knowledge on electrophysiological alterations that are hard to understand. By reporting this case we aim to propose a rationale sequence that should be considered when facing an ECG with these same features, which would enable a greater accuracy to make a definitive diagnosis.
