The LV lead, preferably quadripolar, is best targeted in a postero-lateral position. After implantation, optimal device programming should aim for maximal biventricular pacing and in selected cases further electrical delay optimization might be of use. Even as important, is the implementation of ...

KEYWORDS Heart failure guidelines diagnosis transplant ventricular assist device commissioning service development Introduction Heart failure (HF) is defined, clinically, as a syndrome in which patients have typical symptoms (eg breathlessness, ankle swelling and fatigue) and signs (eg elevated jugular venou...
This corresponded to the intuitive concept that, in cardiomyopathy with left bundle branch block, the lateral wall is the site of latest activation and should be the optimal pacing location.Derval NJais PJournal of the American College of Cardiology...
Interventional CardiologyValve replacementCardiac resynchronization therapy (CRT) can be achieved using biventricular pacing systems in patients with symptomatic chronic heart failure who have a comorbidity of intraventricular conduction delay (IVCD) and QRS duration >120 ms. Current evidence suggests that ...
It is because there are high frequencies of old age and heart failure in patients with pacemaker, implantable cardioverter defibrillator (ICD) for primary prevention and cardiac resynchronization therapy (CRT) device. 7) Using CIED, heart rhythm can be monitored although it is limited. However, AF...
The working heart is a precursor for this zone's presence, since it disappears when cardioplegia arrests the heart [12]. (a) (b) Figure 6. (a) Mid-septal hyperechogenic line shown in low and high-resolution echocardiogram; (b) septum high-resolution ultrasound image at transducer frequency...
Current epicardial pacing systems are used in patients with congenital heart disease, lack of venous access, history of recurrent device infections, or subjects who require CRT in whom a coronary sinus (CS) lead is not feasible. Current epicardial leads are implanted through various minimally ...
According to the 2016 European Society of Cardiology (ESC) Heart Failure Guidelines, the patients with a life expectancy longer than 1 year and good functional status had a IA class recommendation for ICD placement if there was ischemic preconditioning (unless the subjects have had a myocardial ...
This can be primarily attributed to a higher stroke volume per given end-diastolic volume, potentially indicative of intrinsic sex differences in cardiac function or responses to hemodynamic stress. This variation is independent of potential confounding variables like age, blood pressure, heart rate, ...
