The P and the Ta waves of two patient groups with A-V block were magnified with a direct-current amplifier and recorded at a high paper speed. In Group A patients (those without serious cardiovascular complications except A-V block) the P and the Ta waves were recorded in the opposite direction in every lead and there was a linear relationship between the amplitude of the P and the Ta waves. The atrial gradient was nearly zero. There existed a positive correlation between the P + Ta time and… CONTINUE READING
