An Interesting Case of Permanent His-Bundle Pacing and a Review of the Current Literature
نویسندگان
چکیده
Permanent His-bundle pacing (HBP) is a true physiological form of ventricular pacing that has been shown in recent years to be both safe and feasible in clinical practice. However, there are limited data about its long-term performance, especially when compared with both right ventricular and biventricular pacing. In this article, we present a thought-provoking case study that illustrates the usefulness of permanent HBP in a patient with long-standing complete infranodal heart block and progressive heart failure, and discuss the current literature highlighting the evidence behind this form of permanent pacing.

Case Report Safe Right Bundle Branch Block Pattern During Permanent Right Ventricular Pacing
It is known that an electrocardiogram (ECG) after transvenous right ventricular (RV) pacing should yield left bundle branch block (LBBB) QRS patterns. When right bundle branch block (RBBB) pacing morphology appears in a patient with a permanent or temporary transvenous RV pacemaker, myocardial perforation or malposition of the pacing lead must be ruled out, even though the patient may be asympt...
متن کاملHis Bundle Pacing: Techniques and Outcomes.
Traditional right ventricular pacing prolongs the electrical and mechanical activation of the heart, which reduces the pump function, and in selected patients may lead to pacing-induced heart failure. Pacing the His bundle preserves the normal or near-normal activation pattern of the ventricles that prevents the detrimental effects of right ventricular pacing. This review discusses the techniqu...

The feasibility of resynchronizing ventricular activation by permanent pacing of the His bundle region has been previously described, and has clinical advantages over traditional right ventricular (RV) apical pacing.1–4 The physiologic benefit of permanent His bundle pacing (HBP) is the ability to stimulate the ventricles through the intrinsic His-Purkinje system, which results in synchronous e...
متن کاملStep-wise Approach to Permanent His Bundle Pacing
There has been a recent upsurge of interest in permanent His bundle pacing, given increased understanding and appreciation of the role dyssynchronous ventricular activation plays in congestive heart failure and atrial fibrillation. Permanent His bundle pacing gives implanters the ability to avoid causing ventricular dyssynchrony in patients dependent on ventricular pacing, and can provide an al...
متن کاملOvercoming left bundle branch block by permanent His bundle pacing: Evidence of longitudinal dissociation in the His via recordings from a permanent pacing lead
Introduction Narrowing of the QRS and overcoming left bundle branch block (LBBB) with His bundle pacing (HBP) has been previously described. We present the first 2 reported cases of left bundle branch (LBB) delay with evidence of a split His electrogram during unipolar mapping from the tip of the His bundle (HB) lead during pacemaker implantation. These findings suggest that the site of LBB del...
