1 Factors related to congenital heart disease, such as underlying anatomy, surgical repair technique and scars, can all be considered as AA substrates. Of these, AA is one of the leading causes for hospital admissions in ACHD care.

Focal AT at the aorta-mitral annulus conjunction (AMC) is uncommon. Hence, the electrophysiological and ablation target characteristics are poorly described.

Atrioventricular nodal reentry tachycardia (AVNRT), identified as the most prevalent form of regular tachycardia in humans,3 exhibits a strong relationship with the anatomy and physiology of the AV node (AVN) and junction. Despite the temporal distance, Koch's triangle and pyramid remain a repository of unresolved mysteries.

ABSTRACT Atrial flutter (AFL), defined as macro-re-entrant atrial tachycardia, is associated with debilitating symptoms, stroke, heart failure, and increased mortality. Atypical AFL is a heterogenous group of re-entrant atrial tachycardias that most commonly occur in patients with prior heart surgery or catheter ablation.

MY Interpretation of Today's Initial ECG: I've labeled key findings in Figure-2 for today's initial ECG: The rhythm is sinus tachycardia at ~105/minute. The sinus tachycardia is a definite concern that something acute may be ongoing. Figure-2: I've labeled t he initial ECG. All intervals ( PR, QRS, QTc ) are normal.

The finding of a fairly regular, wide tachycardia without clear sign of atrial activity ( especially when seen in an acutely symptomatic patient ) — should immediately prompt a diagnosis of VT until proven otherwise. The rhythm looks fairly regular — and atrial activity is absent.

The best course is to wait until the anatomy is defined by angio, then if proceeding to PCI, add Cangrelor (an IV P2Y12 inhibitor) I sent the ECG and clinical information of a 90-year old with chest pain to Dr. McLaren. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ). A normal PR interval.
