Key result
Normally functioning DVI pulse generators can cause complex cardiac arrhythmias, such as pseudopseudofusion beats and variations in atrial cycle length, which must not be interpreted as malfunction.

Clinicians must distinguish normal DVI behavior from malfunction to avoid misdiagnosis; extends device ECG descriptions but leaves open contemporary relevance.
Clinicians must recognize that certain complex arrhythmias in patients with DVI pulse generators are due to normal device function rather than malfunction.
Barold et al. (1980) studied Pacemaker arrhythmias. Normally functioning AV Demand (DVI) pulse generators was evaluated. Normally functioning DVI pulse generators can cause complex cardiac arrhythmias, such as pseudopseudofusion beats and variations in atrial cycle length, which must not be interpreted as malfunction.
