In ventricular septal defects, left ventricular hypertrophy, biventricular hypertrophy, or right ventricular hypertrophy ECG may be present.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
Sometimes, the amplitude of sinus P wave is extremely low, close to equipotential line, and it is easy to be misdiagnosed as junctional rhythm.
Negative direction of QRS main wave in aVL lead
The atrial foci originating from the anterior and posterior walls of the right atrium form an inverted P wave and positive and negative biphasic P wave in the V1 lead, respectively.
