Wandering atrial pacemaker occurs when multiple areas (ectopic foci) ... WAP must have at least three distinctly different P wave morphologies and a ventricular rate of less than 100 bpm.

There are clearly extra QRS complexes that are of different morphology compared to the QRS complexes with preceding p waves, ie, the sinus beats. The extra QRS complexes are broader and bigger ...

Ectopic P waves are also commonly seen in multifocal atrial tachycardia, ... Symptoms of atrial tachycardia depend on the ventricular rate and the duration of the tachycardia.

The diagnosis is sinus tachycardia, right ventricular pacemaker, P-wave synchronous ventricular pacing (A-sensed V-paced), pseudo second-degree AV block due to failure of atrial sensing. There is ...

The aim of this study was to investigate the effect of obesity on dispersion of P-wave duration and QTc interval in obese women. Forty-two obese women (Body mass index (BMI)=40±3 kg/m2, mean age ...

Other ECG features can signal impending torsades, including distortions of the T-U wave, visible T-wave alternans, new ventricular ectopic beats, and "couplets and nonsustained polymorphic ...

(HealthDay)—The ventricular ectopic QRS interval (VEQSI) can identify post-myocardial infarction (MI) patients with prior serious ventricular arrhythmia, according to a study published online ...
