Right ventricular pacing is has deletorius effects due to left ventricular dysynchrony and remodelling and may result in heart failure. Over the last decade, His bundle pacing has emerged as the most physiologic form pacing. However, it has limitations, such as higher capture thresholds, lower R wave amplitudes, atrial oversensing, and increased risk for lead revisions from late threshold increase with subsequent premature battery depletion, which has prevented a wider adoption of this technique in routine clinical practice. Left bundle branch pacing has been developed as an alternative physiologic pacing strategy that overcomes most of His bundle pacing limitations. This article summarizes the current status of left bundle branch pacing. Keywords: His bundle pacing, left bundle branch pacing, cardiac resynchronization, therapy heart failure.
