The electrocardiographic interpretation of pacemaker algorithms enabling minimal ventricular pacing

Cardiac pacing from the apex of the right ventricle has been shown to result in left ventricular dysfunction, atrial fibrillation and increased mortality. To counter this, one of the strategies developed, is to avoid ventricular pacing when not necessary, using programmable algorithms to minimize ventricular pacing. There are seven algorithms available from five manufacturers. Four of the manufacturers have mode conversion algorithms that pace AAI(R), but in the presence of failed atrio-ventricular (AV) conduction, demonstrate algorithm offset and convert to DDD(R) with ventricular pacing.
