RESUMO
Objective To assess the value of ECG in the diagnosis of acute pulmonary embolism (APE). Methods Twenty-eight patients with APE were included,with mean age of 56?16,and PaO 2,electrocardiogram (ECG),echocardiogram (ECHO) and ventilation/perfusion lung scan were performed. Results 96.4% patients had risk factors,and had different degree of hypoxia. 92.9% patients had ECG changes,most of whom (57.1%) showed ST-T changes. The ventilation/perfusion lung scan confirmed the diagnosis. Conclusion Considering the clinical symptom,arterial blood gas analysis,the early changes of ECG are useful in the diagnosis of the APE.
RESUMO
Objective To study the factors effecting the formation of the ventricular aneurysm post myocardial infarction (MI) and evaluate the diagnostic methods.Methods 23 MI patients with ventricular aneurysm confirmed by left ventricular angiography were observed for electrocardiogram (ECG), echocardiogram (ECHO), coronary disease and collateral vessels formation. Results All patients had LAD disease, 65.2% patients had three coronary disease, and those with class Ⅲ collateral vessels circulation only 17.4%. Compared to ECHO by which only 4 patients were found aneurysm, the positive rate by ECG was 82.6%. Conclusion Patients with multiple coronary disease and without enough collateral vessels are expected to form ventricular aneurysm. ECG is more sensitive than ECHO for diagnosis of ventricular aneurysm post MI
