2024年10月8日 · 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 …

2021年6月11日 · It is a type of supraventricular tachycardia that can occur in both normal hearts and in congenital heart disease. The ECG usually has the following characteristics: Rate > 100bpm; If seen the P waves have an atypical morphology; There is a narrow QRS; We think of Atrial tachycardias as falling into 3 groups: Focal Atrial Tachycardia. It is REGULAR

Electrocardiogram (ECG or EKG). This is the most common test to diagnose tachycardia. An ECG shows how the heart is beating. Small sensors, called electrodes, attach to the chest and sometimes the arms and legs. Wires connect the sensors to a computer, which prints or displays results. Holter monitor. A Holter monitor is a small ECG device. It ...

2024年11月28日 · An ECG is the most common and essential tool for diagnosing atrial tachycardia. It provides a visual representation of the electrical activity of the heart and helps physicians identify any abnormal rhythms or conduction problems.

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.

2010年4月10日 · Atrial tachycardia has a more or less regular heart rate > 100 bpm, with narrow QRS complexes but P-waves that do not originate from the sinus node but from another site in the atria. The P-waves therefore have a different configuration and their non-sinus origin can easily be recognized if the P waves are negative in I and/or aVF.

2022年12月5日 · In multifocal atrial tachycardia (MAT), the ECG shows an irregular rhythm with at least 3 different P-wave morphologies, and the average atrial rate is >100 beats/min. 1 This rhythm most often occurs in the setting of severe pulmonary disease or hypomagnesemia.
