Comprehensive non-invasive assessment of electrocardiographic abnormalities and cardiac arrhythmias in patients with genetically confirmed mitochondrial diseases.

Background: There is limited data on cardiac arrhythmias and ventricular repolarization and dispersion abnormalities in patients with mitochondrial diseases (MitD).

Methods: Consecutive 40 patients with genetically proven MitD and 35 healthy controls were studied. Among other examinations all subjects underwent 24-h Holter recording and 12‑lead electrocardiography (ECG) with corrected QT (QTc), QT dispersion (QTd), Tp-e and Tp-e/QT ratio assessment.

"The post-pulmonary syndrome - results of echocardiographic driven follow up after acute pulmonary embolism".

Introduction: The concept of post Pulmonary Embolism syndrome includes various combinations of functional, haemodynamic or imaging abnormalities in patients after pulmonary embolism (PE). Although residual obstruction of pulmonary vascular bed is suggested to be a major cause of post Pulmonary Embolism syndrome (post-PE syndrome) other cardiopulmonary abnormalities can be responsible for functional impairment. Therefore, we analyzed the frequency of post-PE syndrome and its potential causes.
