[Characterization of arrhythmia in pulmonary hypertension in patients with bronchial obstructive diseases].

To study the pattern and incidence of arrhythmias in relation to the mean pulmonary trunk pressure (MPTP), 24-hour SCG monitoring and Doppler pulse EchoCG were performed in 32 patients with chronic obstructive lung disease and in 13 patients with bronchial asthma. The summarized results of 24-hour ECG suggest that the number and grades of arrhythmias increase when MPTP becomes more than 13 mm Hg. There is a highly significant mean force correlation between MPTP and complicated cardiac arrhythmias (paroxysmal supraventricular tachycardia, coupled ventricular extrasystoles, and unsteady ventricular tachycardia). A more than 13 mm increase in MPTP may be a predictor for the assessment of a risk of the existence of complicated cardiac arrhythmias on an exacerbation of bronchial obstructive lung diseases.
