A 43-year-old woman presented with a 1-year history of recurring symptoms of sudden onset of fatigue, palpitations, dyspnea, chest pain, lightheadedness, and nausea that were associated with standing and resolved with sitting. These symptoms began 1 month after mild COVID-19 infection. At presentation, while supine, blood pressure (BP) was 123/70 mm Hg and heart rate (HR) was 90/min; while seated, BP was 120/80 and HR was 93/min; after standing for 1 minute, BP was 124/80 and HR was 119/min. Physical examination results were normal. Oxygen saturation was 98% at rest while breathing room air. She had no oxygen desaturation during a 6-minute walk test but walked only 282 m (45% predicted). Complete blood cell count, morning cortisol, and thyrotropin blood levels were normal. Electrocardiogram (ECG), chest computed tomography, pulmonary function testing, methacholine challenge, bronchoscopy, echocardiography, and cardiac catheterization findings were normal. During tilt table testing, the patient experienced lightheadedness and nausea when moved from horizontal to the upright position. Results of the tilt table test are shown in the Table and Figure.

In December, 2019, a pneumonia associated with the 2019 novel coronavirus (2019-nCoV) emerged in Wuhan, China. We aimed to further clarify the epidemiological and clinical characteristics of 2019-nCoV pneumonia.
METHODS:
In this retrospective, single-centre study, we included all confirmed cases of 2019-nCoV in Wuhan Jinyintan Hospital from Jan 1 to Jan 20, 2020. Cases were confirmed by real-time RT-PCR and were analysed for epidemiological, demographic, clinical, and radiological features and laboratory data. Outcomes were followed up until Jan 25, 2020.
FINDINGS:
Of the 99 patients with 2019-nCoV pneumonia, 49 (49%) had a history of exposure to the Huanan seafood market. The average age of the patients was 55·5 years (SD 13·1), including 67 men and 32 women. 2019-nCoV was detected in all patients by real-time RT-PCR. 50 (51%) patients had chronic diseases. Patients had clinical manifestations of fever (82 [83%] patients), cough (81 [82%] patients), shortness of breath (31 [31%] patients), muscle ache (11 [11%] patients), confusion (nine [9%] patients), headache (eight [8%] patients), sore throat (five [5%] patients), rhinorrhoea (four [4%] patients), chest pain (two [2%] patients), diarrhoea (two [2%] patients), and nausea and vomiting (one [1%] patient). According to imaging examination, 74 (75%) patients showed bilateral pneumonia, 14 (14%) patients showed multiple mottling and ground-glass opacity, and one (1%) patient had pneumothorax. 17 (17%) patients developed acute respiratory distress syndrome and, among them, 11 (11%) patients worsened in a short period of time and died of multiple organ failure.
INTERPRETATION:
The 2019-nCoV infection was of clustering onset, is more likely to affect older males with comorbidities, and can result in severe and even fatal respiratory diseases such as acute respiratory distress syndrome. In general, characteristics of patients who died were in line with the MuLBSTA score, an early warning model for predicting mortality in viral pneumonia. Further investigation is needed to explore the applicability of the MuLBSTA score in predicting the risk of mortality in 2019-nCoV infection.
