8 paź 2024 · Focal atrial tachycardia (FAT): Consistent, abnormal P wave morphology indicating an ectopic focus. The term FAT is commonly used synonymously with atrial tachycardia, a broader term referring to any form of SVT originating within the atria but outside of the sinus node.

4 cze 2024 · Focal atrial tachycardia (focal AT) is characterized as a rapid regular rhythm arising from a discrete area within the atria. It occurs in a wide range of clinical conditions, including catecholamine excess, digoxin toxicity, congenital heart disease, and cardiomyopathy.
26 cze 2023 · A focal atrial tachycardia is an arrhythmia with electrical impulses originating and confined within the atria. Focal tachycardia typically occurs in the setting of increased metabolic demand and stress, like infection, hypoxia, etc. Focal atrial tachycardia generally is a benign arrhythmia.
This study sought to report P-wave morphology (PWM) from a series of paraseptal (PS) atrial tachycardia (AT), revise then prospectively evaluate a simplified PWM algorithm against a contemporary consecutive cohort with focal AT.
30 maj 2023 · Focal ATs (also referred to as atrial ectopic tachycardias) arise from a single site within the left or right atrium, in contrast to macroreentrant atrial arrhythmias (eg, atrial flutter) and atrial fibrillation, which involve multiple sites or larger circuits.
17 lis 2016 · A wide-QRS tachycardia refers to one with a QRS duration >120 ms (Table 3). In clinical practice, SVT may present as narrow- or wide-QRS tachycardias, and most of them usually, although not invariably, manifest as regular rhythms.
Atrial tachycardia is defined as a regular atrial activation from atrial areas with centrifugal spread, caused by enhanced automaticity, triggered activity or microreentry. New ECG classification differentiates between focal and macroreentrant atrial tachycardia.
