Differentiating Infra-Hisian Block from other Diseases

On 31 December 2019, the World Health Organization (WHO) was formally notified about a cluster of cases of pneumonia in Wuhan City.^[1]
Ten days later, WHO was aware of 282 confirmed cases, of which four were in Japan, South Korea and Thailand
The virus responsible was isolated on 7 January and its genome shared on 12 January.The cause of the severe acute respiratory syndrome that became known as COVID‐19 was a novel coronavirus, SARS‐CoV‐2
ARDS is one of the most important causes of hospital and ICU admission due to COVID.
Many autopsies studies reported ARDS to be the cause of death in patients dying due to respiratory complications of COVID.

As of July 19 2020 the number of total cases worldwide are 14,043,176 including 597,583 deaths, reported to WHO.

COVID-19-related ARDS was divided into three categories based on oxygenation index (PaO2/FiO2) on PEEP ≥ 5 cmH2O: mild (200 mmHg ≤ PaO2/FiO2 < 300 mmHg), mild-moderate (150 mmHg ≤ PaO2/FiO2 < 200 mmHg), and moderate-severe (PaO2/FiO2 < 150 mmHg).^[2]
