| Abstrakt: |
Combined findings in 89 patient over 20 with an interatrial septum defect (IASD) have shown that the frequency of pulmonary hypertension increases with age. Electrocardiographic criteria of pulmonary hypertension do not allow a reliable diagnosis with pressures below 50 mm Hg. Tone I amplitude, Q - Tone I duration, the extent of splitting and correlation of Tone II components cannot be used as PCG criteria of pulmonary hypertension either. The Q - "systolic murmur peak" interval decreases as pulmonary arterial pressure goes up. Systolic murmur amplitude is not relevant for the diagnosis of either the IASD, or pulmonary hypertension. Diastolic murmurs associated with secondary IASD are a more frequent finding, but show no distinctive features. |
