Rationale: A novel COVID-19 with a severe acute respiratory syndrome or pneumonia had arisen in Wuhan, China in December 2019. Emerging atrial fibrillation in COVID-19 patients is highly significant in cardiovascular medicine. A newly coronary artery spasm in the presentation of COVID-19 infection has certainly a risk impact on both morbidity and mortality of COVID-19 patients. Wavy triple an electrocardiographic sign (Yasser Sign) is an innovated sign of hypocalcaemia linked to tachypnea and acute respiratory distress. Patient concerns: An elderly male COVID-19 patient presented to physician outpatient clinic with bilateral pneumonia, atrial fibrillation, evidence of coronary artery spasm, and Wavy triple an electrocardiographic sign (Yasser Sign). Diagnosis: COVID-19 pneumonia with coronary artery spasm and the Wavy triple an electrocardiographic sign (Yasser Sign). Interventions: Chest CT scan, electrocardiography, oxygenation, and echocardiography. Outcomes: Gradual dramatic clinical, electrocardiographic, and radiological improvement had happened. Lessons: The reversal of electrocardiographic ST-segment depressions in a COVID-19 patient after adding oral nitroglycerine is an indicator for the presence of coronary artery spasm. It signifies the role of the anti-infective drugs, anticoagulants, antiplatelet, and steroids in COVID-19 patients with bilateral pneumonia, AF, coronary artery spasm are effective therapies. The disappearance of AF after initial therapy may a guide for a good prognosis in this case study. The evanescence of Wavy triple ECG sign as a hallmark for the existence of the Movable-weaning phenomenon of hypocalcaemia is recommended for further wide-study.
