Background: Premature ventricular complex (PVC) is a frequent finding in the general population. The atrial conduction time (ACT) is the period between the electrocardiographic P wave and the atrial mechanical contraction, and its prolongation indicates an atrial electromechanical delay (EMD). In our study, we compared atrial conduction parameters by echocardiographic methods between patients with frequent PVC and healthy control subjects. Methods:The study included 54 patients with PVC and 54 healthy volunteers. Atrial conduction parameters were measured with echocardiographic examination. The time difference between the p wave and the Am wave was measured in the septal, lateral, and tricuspid annulus regions. The interatrial EMD, left atrial intra-atrial delay, and the right atrial intra-atrial delay were calculated from these measurements. The groups were compared for demographic and electrocardiographic features and echocardiographic parameters.Results: Left intra-atrial EMD, right intra-atrial EMD, and interatrial EMD were significantly longer in the patient group (p = .001, p < .001, p < .001, respectively). PA lateral, PA septal, and PA tricuspid durations were significantly prolonged in the patient group (all p < .001). All ACT parameters were significantly prolonged in patients with PVC QRS duration of 150 ms and above (all p < .001). All ACT parameters were prolonged in PVCs of right ventricular origin than those of left ventricular origin (all p < .001). ACT parameters were prolonged in patients with a coupling interval time below 485 ms (all p < .001).Conclusions: Atrial conduction times are prolonged in patients with frequent PVC.

“…The coherence and similarity of the QRS morphology between intrinsic QRS and paced QRS can indirectly reflect the difference of the sequence of downward transmission and ventricular excitation. So the QRS duration is an important indicator of the synchronization of the contractions of both ventricles, which affects the risk of death and heart failure in patients after pacing surgery [30][31][32] . LBBAP proved its effectiveness both in maintaining a normal QRS duration and in generating narrower QRS duration in our study.…”

Background : The invention of His bundle pacing technology bring a new revelation-Left bundle branch area pacing (LBBAP). LBBAP engages in the electrical activation through left bundle branch area and produces ventricular electrical synchronization, which can grab more cardiac cells and increase the safety of pacing compared to His bundle pacing (HBP). This pacing has been considered as an attractive mode to achieve normal physiological pace markers. However,as a new technology, LBBAP is still in the stage of clinical exploration and lacks adequate evaluation. Objective :This study aims to investigate the electrocardiogram characteristics,pacing parameters,the safety and the effectiveness of LBBAP. Method : A computerized search of PubMed, Embase, The CochraneLibrary, Chinese CNKI, CBM, Wanfang and Weipu Chinese Sci-tech Journals database for effects of Left bundle pacing. The baseline characteristics, the successful rate of implantation, capture threshold, R-wave amplitude, pacing impedance, QRS duration and follow-up date were extracted and summarized. Results : Thirteen studies including 618 patients were included in this analysis. The overall successful rate for implantation was 92.1%.Permanent LBBAP resulted in narrow QRS duration when patients with QRS duration¿120ms after implantation (P=0.02). QRS duration and capture threshold of LBBAP remained stable during follow-up. Moreover, there was a trend of increased R-wave amplitude and declined pacing impedance at follow-up compared to implantation (P=0.003 and P¡0.00001, respectively). Conclusion : Permanent LBBAP has shown promising results in pacemaker-indicated patients. Good electrical synchronization, high success rates, and stable pacemaker parameters point to the unparalleled advantages of LBBAP in physiological pacing.

Relation between QRS Duration and Atrial Synchronicity in Patients with Systolic Heart Failure

Abstract: Among patients with systolic HF, prolonged QRSd is associated with impaired intra-atrial and inter-atrial synchrony. Atrial and ventricular dyssynchrony parameters were well-correlated with each other.
