This article provides a detailed explanation of pacemaker codes, including NBG codes for antibradycardia and adaptive-rate pacing. It covers the types of sensing and stimulation (atrial, ventricular, dual), as well as multisite pacing and rate modulation. The document outlines the characteristics and programming complexities of single and double chamber pacemakers. Emphasis is placed on the advantages of each type, such as ease of lead positioning and longevity, while addressing critical concepts like AV synchrony and pacing intervals.

Single Chamber Pacemaker - VVI • Lead easy to position • Easy to program and to control • Excellent longevity • One stimulation / sensing threshold
Double Chamber Pacemaker • 2 leads to position • More complex programming • Excellent longevity • Two stimulation / sensing thresholds • AV-synchrony • No pacemaker syndrome
