[Current limits of the long duration rhythmic holter: A real life study]. / Limites actuelles du holter rythmique de longue durée : une étude vie réelle.

BACKGROUND: Syncope or stroke remain frequently without any explained diagnosis. Long duration holter ECG is an available tool to diagnose arrhythmias. However, this tool is subject to availability of the recorders. AIM: Report a single center experience with long duration holter ECG in clinical practice, in the different cardiology and neurology indications, and to assess the different delays until achievement of a diagnosis. METHODS AND RESULTS: The device (Sorin Spiderflash) was used for 48 patients between January 2018 and June 2018. The holter was applied for a mean duration of 10±4days. The mean age was 55+19 years-old. 20 patients (42%) were explored for a stroke or transient ischemic attack (TIA), 18 (36%) for palpitations, 6 (12%) for syncope and 4 (8%) for evaluation of arrhythmias management. An abnormality has been recorded in 11 (22%) patients and a treatment has been administered in 5 patients (10%). Regarding, the timing of the exam, the mean time between the index event and the indication was 39 days. The mean time between the indication and the availability of the device was 32 days. 16 Days was the mean time for lecture and 23 days was the mean time between the result and the appointment with the cardiologist and neurologist. CONCLUSION: In this registry, the management of patients by non-invasive long duration holter ECG monitoring may be improved regarding the timing of the exams, their lecture and new appointments with the physicians.

[Platypnea-orthodeoxia syndrome: A case of hypoxemia associated with a patent foramen ovale]. / Platypnée-orthodéoxie: un cas rare d'hypoxémie secondaire d'une réouverture post-traumatique du foramen ovale perméable.

Platypnea-orthodeoxia syndrome is a rare disease characterized by dyspnea and oxygen desaturation in the upright position with improvement in the supine position. We report a case of an 87-year-old woman with a recent history of traumatic hip, spine deformity and vertebral compression fracture, referred due to dyspnea oxygen desaturation. Thoracic tomodensitometry excluded the diagnosis of pulmonary embolism. Transthoracic echocardiography, with intravenous administration of agitated saline contrast solution, revealed the presence of atrial septal defect associated with a right to left shunting and mild enlargement of aortic root. Surgical closure of atrial septal defect resulted in resolution of the syndrome.
