Nodal automaticity
The sinoatrial node has spontaneous diastolic depolarization, while atrial and ventricular myocytes exhibit different action-potential patterns.
Conduction hierarchy
Atrial activation and AV nodal delay normally precede rapid ventricular conduction through the His–Purkinje network.
Arrhythmia mechanisms
Abnormal automaticity, triggered activity and re-entry can produce distinct rhythm disturbances depending on substrate and triggers.
Mapping and evidence
Surface ECG, ambulatory monitoring, imaging and invasive studies may localize mechanisms; results require integration with clinical risk.
