If You Don’t Understand the Technology That Saves Lives, You Don’t Belong in the Cath Lab
Temporary pacing is not “plug and play.” It is a high-risk intervention that demands a clear understanding of mode selection, capture thresholds, sensing, and clinical context.
This visual walkthrough breaks down temporary/external cardiac pacing, including transvenous and epicardial wires, pacer box controls (rate, output, sensitivity), and why mode choice (VVI, DDD, DOO, VOO) matters more than many realize. Whether you are managing bradycardia with hemodynamic compromise or using overdrive pacing for tachyarrhythmia suppression, small setup errors can have outsized consequences.
For cath lab technologists, this is core knowledge, not optional familiarity.
