Then I always look to see if the initial deflection of the QRS has a lot of voltage change per change in time (seen in tachycardias that are initiated from above the ventricle because the propagate through fast conducting purkinje fiber.

Ivabradine is an anti-arrhythmic agent that reduces the heart rate through inhibition of the pacemaker current of the sinoatrial node. It has been used to treat both inappropriate sinus tachycardia and sinus tachycardia related to heart failure in children and adults.

Introduction Heart transplantation (HT) is the only treatment option in children with heart failure secondary to cardiomyopathies and non-reparable congenital heart diseases. Three patients developed symptomatic sinus node dysfunction at 18, 25, and 38 days and received permanent pacemakers.

CRT is used in heart failure with reduced ejection fraction. According to the Universal Definition and Classification of Heart Failure, heart failure with reduced ejection fraction has left ventricular ejection fraction of 40% or less. CRT stands for cardiac resynchronization therapy.

His medical history includes hypertension, a decade-long battle with diabetes, ischemic heart disease, a coronary bypass graft surgery ten years ago, a diagnosis of congestive heart failure for the last five years, and a prior ICD implantation five years ago.

Background:Left bundle branch area pacing (LBBAP) may be associated with greater improvement in left ventricular ejection fraction and reduction in death or heart failure hospitalization when compared with biventricular pacing (BVP) in patients requiring cardiac resynchronization therapy (CRT).
