Direct constant His bundle pacing: hemodynamic benefit and long-term clinical prospect

Analysing the example of unusual case of a successful direct constant His bundle pacing, we would like to draw specialist’s attention to details of procedure and some important electrophysiological particularities we have come across during operation. Long-term (7 years) results ( pacing options, ECG data, changes of left ventricle ejection fraction and patient’s quality of life) were considered too.
