Abstract Knowing the patient’s current cardiovascular disease (CVD) status, as well as the patient’s current and future CVD risk, helps the clinician make more informed patient-centered management recommendations towards the…
Abstract Cardiometabolic risk factors in children and adolescents track into adulthood and are associated with increased risk of atherosclerotic cardiovascular disease. The purpose of this review is to examine the…
Highlights • Even though at least a quarter of the world’s FH population lives in Southeast and East Asia, there are substantial gaps in knowledge regarding the epidemiology of FH…
Narrow-QRS complexes (≤120 ms) are due to activation of the ventricles via the His-Purkinje system, consistent with origin of the arrhythmia above or within the His bundle. However, early activation…
Definitions Ventricular tachycardia (VT) is defined as a tachycardia (rate > 100 beats per minute [bpm]) with three or more consecutive beats that originates in the ventricles. , Accelerated idioventricular…
Definitions The anatomic basis of atrioventricular reentrant tachycardia (AVRT) is an abnormal connection ( accessory pathway [AP] ) between the atrial and ventricular myocardium. One limb of the reentrant circuit…
Atrial premature beats An atrial premature beat (APB) is characterized by a nonsinus P wave that occurs before the next anticipated sinus beat. Several electrocardiographic leads may be needed to…
Atrioventricular nodal reentrant tachycardia Definition Atrioventricular nodal reentrant tachycardia (AVNRT) denotes reentry in the area of the atrioventricular (AV) node. Several models have been proposed to explain the mechanism of…
Definitions and classification Atrial fibrillation (AF) is characterized by uncoordinated atrial activation without effective atrial contraction. On the electrocardiogram (ECG), AF is characterized by rapid oscillations or fibrillatory waves that…
Wide-QRS tachycardias can be ventricular tachycardia (VT), supraventricular tachycardia (SVT) conducting with bundle branch block (BBB) aberration or through a bystander accessory pathway (AP), or an AP-mediated tachycardia, with reported…
