16.4 ECG Rhythms: Topside (above the junction)

The interpretation of cardiac rhythms is a systematic diagnostic engine. While many students fall into the "pattern recognition trap," the advanced provider must rely on a rule-based algorithmic approach to differentiate between benign physiological variants and life-threatening atrial pathologies. This guide explores the "topside" rhythms originating above the AV junction, focusing on the five-step interpretation method and the clinical nuances of atrial conduction.
