Can second degree type II sinus block cause mild pulmonary hypertension?

Second degree second-degree sinus atrioventricular block does not usually cause mild pulmonary hypertension.
Second degree second-degree sinus block is a condition in which excitation of the sinus node is followed by a partial interruption of its excitability in conduction to the atria, resulting in the heart stopping once in a while and not leading to pulmonary hypertension.
