| Respiratory disease is the chief target of Coronavirus disease 2019 (COVID-19). One-third of patients with severe disease also reported other symptoms including [[Cardiac arrhythmia|arrhythmia]]. According to a study done in Wuhan, China, 16.7% of hospitalized and 44.4% of ICU patients with COVID-19 had arrhythmias.<ref name="WangHu2020">{{cite journal|last1=Wang|first1=Dawei|last2=Hu|first2=Bo|last3=Hu|first3=Chang|last4=Zhu|first4=Fangfang|last5=Liu|first5=Xing|last6=Zhang|first6=Jing|last7=Wang|first7=Binbin|last8=Xiang|first8=Hui|last9=Cheng|first9=Zhenshun|last10=Xiong|first10=Yong|last11=Zhao|first11=Yan|last12=Li|first12=Yirong|last13=Wang|first13=Xinghuan|last14=Peng|first14=Zhiyong|title=Clinical Characteristics of 138 Hospitalized Patients With 2019 Novel Coronavirus–Infected Pneumonia in Wuhan, China|journal=JAMA|volume=323|issue=11|year=2020|pages=1061|issn=0098-7484|doi=10.1001/jama.2020.1585}}</ref> Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilizes S-spike to bind to angiotensin-converting enzyme 2 (ACE2) receptors to enter the cells. Type 1 and type 2 [[pneumocytes]] exhibit ACE 2 receptors in the lung.

| ==== Signs and Symptoms: ====
| |
| Arrhythmia or conduction system disease is the nonspecific clinical presentation of COVID-19. Patients may be tachycardic (with or without palpitations) in the setting of other COVID-19-related symptoms (eg, fever, shortness of breath, pain, etc).
