Predictors of Higher Frequency of Atrial Fibrillation in Patients with Cardiac Resynchronization Therapy
Conclusions: The results of our study provide new data on AF predictors in patients with HF subjected to CRT. There remains a permanent need for new predictors, which might help in patient selection and improvement in response rate.PMID:38138281 | PMC:PMC10745040 | DOI:10.3390/medicina59122178 (Source: Medicina (Kaunas))

Effect of left bundle branch pacing on right ventricular function: A three-dimensional echocardiography study
The effect of left bundle branch pacing (LBBP) on right ventricular (RV) function is not well known, and there is conflicting evidence regarding whether cardiac resynchronization therapy improves RV function. (Source: Heart Rhythm)

Association of neighbourhood ‐level material deprivation with adverse outcomes and processes of care among patients with heart failure in a single‐payer healthcare system: A population‐based cohort study
ConclusionPatients with newly-diagnosed heart failure residing in the most deprived neighbourhoods had worse outcomes and reduced access to care than those less deprived. (Source: European Journal of Heart Failure)

The prevalence of frailty and its effect on the outcome in cardiac resynchronization therapy patients
AbstractFrailty is a complex clinical syndrome associated with aging and comorbidities, which correlates with unfavorable outcomes. However, in heart failure patients, frailty is very common, data is scarce about those, who are eligible for Cardiac Resynchronization Therapy (CRT) implantation. We investigated the incidence of frailty and the association of Frailty Index (FI) with the outcome. Thirty baseline clinical parameters were used by the Rockwood cumulative deficit method to determine patients' FI in our single-center cohort. Based on previous studies, patients with FI ≤ 0.210 were considered as non-frail, th...

Left Bundle Branch Pacing lead for sensing ventricular arrhythmias in Implantable Cardioverter Defibrillator: A Pilot Study (LBBP-ICD study)
Left bundle branch pacing(LBBP) has been suggested as an alternative modality for biventricular pacing in cardiac-resynchronization therapy(CRT) eligible patients. As it provides stable R-wave sensing, LBBP has been recently utilized to provide sensing of ventricular arrhythmia in patients receiving implantable cardioverter defibrillator(ICD) with CRT (Source: Heart Rhythm)

Mechanocardiography detects improvement of systolic function caused by resynchronization pacing
This study compared waveform characteristics during CRT and AAI pacing at similar pacing rates using seismocardiogram (SCG) and gyrocardiogram (GCG), collectively known as mechanocardiogram (MCG). Approach. We included 10 patients with heart failure with reduced ejection fraction and previously implanted CRT pacemakers. ECG and MCG recordings were taken during AAI and CRT pacing at a heart rate of 80 bpm. Waveform characteristics, including energy, vertical range (amplitude) during systole and early diastole, electromechanical systole (QS2) and left ventricular ejection time (LVET), were derived by considering 6 MCG axes a...
