Several markers of atrial or atrioventricular nodal abnormalities such a intervals ... of AF incidence and possibly of stroke incidence. ECG left ventricular hypertrophy is strongly associated ...

The ECG shows regular P waves with terminal P-inversion in V1 (left atrial abnormality). There is no evidence of conduction (complete heart block). The QRS complexes are regular at a rate slightly ...

This is one of the criteria for “left atrial abnormality.” Recent studies have attributed P-wave prolongation to conduction delay between the atria (Bachman’s bundle).

Left atrial enlargement (LAE ... An electrocardiogram (ECG) can provide evidence of changes such as right ventricular hypertrophy, combined ventricular hypertrophy, and occasionally LAE.
