“…However, due to the severe infectious nature of SARS-CoV-2, the patient must be isolated in the ward, so routine auscultation was not possible when doctors were dressed in protective gear 9 . For that reason, on one hand, there was in a great need to perform lung auscultation, on another hand 10 , there was little data on characterizing the lung auscultation for these patients. However, the relationship between the lung auscultatory characteristics and outcomes of patients with SARS-CoV-2 infection are of paramount importance to treat patients and reduce mortality.…”

Objective: SARS-CoV-2 (originally named COVID-2019) pneumonia is currently prevalent worldwide. The number of cases has increased rapidly but the auscultatory characteristics of affected patients and how to use it to predict who is most likely to survive or die are not available. This study aims to describe the auscultatory characteristics and its clinical relativity of SARS-CoV-2 pneumonia by using a wireless stethoscope. Material and methods: A cross-sectional, observational, single-center case series of 30 consecutive hospitalized patients with confirmed SARS-CoV-2 pneumonia at Leishenshan Hospital in Wuhan, China, were enrolled from March 9 to April 5, 2020. Clinical, laboratory, radiological, treatment data and lung auscultation were collected and analyzed. Lung auscultation was acquired by a wireless electronic stethoscope. Auscultatory characteristics of the moderate, severe, and critically ill patients were compared. Results: Kinds of crackles including fine crackles and wheezing were heard and recorded in these patients. Velcro crackles were heard in most critically ill patients (6/10). Besides, patients with Velcro crackles were all dead (6/6). There was no positive lung auscultatory finding in the moderate group and little positive lung auscultatory findings (4/10) in the severe group. Conclusion: Velcro crackles can be auscultated by this newly designed electronic wireless stethoscope in most critically ill patients infected by SARS-CoV-2 and predicts a poor prognosis. Moderate and severe patients without positive auscultatory findings may have a better prognosis.

“…Nearly all critically ill patients with COVID-19 present severe and acute respiratory conditions [ 7 ]. Auscultation is important for these patients, particularly those with severe pneumonia or respiratory dysfunction and those who are intubated and whose breathing is assisted with a ventilator, to ensure accurate diagnosis and to assess disease severity and treatment efficacy [ 8 , 9 ]. In addition, auscultation has been shown to act as an emotional bridge between health staff and patients, who are isolated and separated from their loved ones [ 10 ].…”

“…As a consequence, the safety of stethoscope implementation for chest auscultation during the COVID-19 pandemic has been questioned [ 14 ]. Furthermore, inside the quarantine wards in hospitals, medical staff wearing protective clothing are unable to use conventional stethoscopes because their protective clothing covers their ears [ 9 , 15 ] ( Figure 1 ). As a safer alternative, some experts have suggested using stethoscopes less frequently and ultrasound more frequently [ 16 ], while other experts have stressed the necessity of stethoscope use and auscultation in COVID-19 treatment [ 9 ].…”

Background Chest examination by auscultation is essential in patients with COVID-19, especially those with poor respiratory conditions, such as severe pneumonia and respiratory dysfunction, and intensive cases who are intubated and whose breathing is assisted with a ventilator. However, proper auscultation of these patients is difficult when medical workers wear personal protective equipment and when it is necessary to minimize contact with patients. Objective The objective of our study was to design and develop a low-cost electronic stethoscope enabling ear-contactless auscultation and digital storage of data for further analysis. The clinical feasibility of our device was assessed in comparison to a standard electronic stethoscope. Methods We developed a prototype of the ear-contactless electronic stethoscope, called Auscul Pi, powered by Raspberry Pi and Python. Our device enables real-time capture of auscultation sounds with a microspeaker instead of an earpiece, and it can store data files for later analysis. We assessed the feasibility of using this stethoscope by detecting abnormal heart and respiratory sounds from 8 patients with heart failure or structural heart diseases and from 2 healthy volunteers and by comparing the results with those from a 3M Littmann electronic stethoscope. Results We were able to conveniently operate Auscul Pi and precisely record the patients’ auscultation sounds. Auscul Pi showed similar real-time recording and playback performance to the Littmann stethoscope. The phonocardiograms of data obtained with the two stethoscopes were consistent and could be aligned with the cardiac cycles of the corresponding electrocardiograms. Pearson correlation analysis of amplitude data from the two types of phonocardiograms showed that Auscul Pi was correlated with the Littmann stethoscope with coefficients of 0.3245-0.5570 for healthy participants (P<.001) and of 0.3449-0.5138 among 4 patients (P<.001). Conclusions Auscul Pi can be used for auscultation in clinical practice by applying real-time ear-contactless playback followed by quantitative analysis. Auscul Pi may allow accurate auscultation when medical workers are wearing protective suits and have difficulties in examining patients with COVID-19.

“…The dominant infected patients had not yet been effectively controlled, and the invisible patients had come to light. 1 , 2 Despite the confirmed COVID-19 patients have been strictly quarantined, protective measures have been taken for uninfected patients, such as masks, shelters and vaccination. 2 , 3 So, hundreds of millions of Chinese have offered vaccination against SARS -CoV-2 with no fee.…”

At the moment, the SARS-CoV-19 pandemic is still attacking the health of humanity, and vaccines are the primary health strategy to eradicate this global challenge. So, with the exception of the SARS-CoV-2 vaccine, no vaccine for any disease has been brought to clinical use so quickly. Therefore, even with strict management, it can still bring some special adverse effects. One of the most notable is the adverse cardiovascular reactions to SARS-CoV-2 vaccines. No case reports of individuals with irreversible arrhythmia complications following the SARS-CoV-2 vaccine have been found in the available literature. We report the first case of a postoperative man with Marfan syndrome with atrial fibrillation after receiving the SARS-CoV-2 vaccine.
