==Overview==
[[Sudden cardiac death]] is [[defined]] as natural [[death]] from [[cardiac]] [[causes]] developed by abrupt loss of consciousness within one hour of onset of acute change in [[cardiovascular]] status. Preexisting [[heart]] [[disease]] may or may not be present at the time of the [[cardiac arrest]]. Sudden onset of [[chest pain]], [[dyspnea]] or [[palpitations]]  and other [[symptoms]] of [[arrhythmia]] may precede the onset of [[cardiac arrest]]. During the outbreak of [[COVID-19]], the number of out-of-hospital [[cardiac arrest|cardiac arrests]] in Italy  increased and [[prognosis]] of in-hospital [[cardiac arrest]] was generally poor. Factors related to medical services restriction, as well as the side effects of drugs and [[thrombotic]] [[complications]] related to [[COVID-19]], increased the number of [[cardiac arrest]] during [[COVID-19]] pandemic.  
[[SARS-COV2]] which causes [[coronavirus disease 2019]] ([[covid-19]]) led to global [[pandemic]] on March 11, 2020, is an enveloped B-[[coronavirus]] transmitted via [[respiratory]] droplets, attached via viral [[spike protein]] to [[angiotensin-converting enzyme 2 receptor]] ([[ACE2 receptor]]) causing [[clinical asyndrome]] of [[coronavirus disease 2019]]. Severe [[covid-19]] may progress to develope [[acute respiratory distress syndrome]], [[cardiovascular]] [[complications]], [[shock]], and [[death]]. [[Cardiac arrest]] is  often unexpected and acute event may present in every hospitalized [[patient]]. Abnormal [[vital signs]] can be the predictos of [[in-hospital cardiac arrest]]. During the outbreak of [[covid-19]], there were increase reports of [[in-hospital]] [[cardiac arrest]] ([[IHCA]]), [[out-of hospital]] [[cardiac arrest]] ([[OHCA]]), lower rate of successful [[cardiopulmonary resuscitation]] ([[CPR]]), and increased [[mortality]]. 30-days [[mortality]] in [[covid-19]] [[patients]] was increased 3.4 fold in [[OHCA]] and 2.3 fold in [[IHCA]] compared with pre-pandemic period. [[survival]] of [[in-hospital]] [[cardiac arrest]] was poor. Factors related to restricted or delay access to emergency care, late presentation of [[ACS]] or [[heart failure]] in hospital, avoidance of witness [[CPR]] in public due to fear contracting [[covid-19]], as well as the side effects of [[drugs]] and [[thrombotic]] [[complications]] related to [[covid-19]] led to higher [[incidence]] of [[cardiac arrest]] during [[covid-19]] pandemic.

Overview

SARS-COV2 which causes coronavirus disease 2019 (covid-19) led to global pandemic on March 11, 2020, is an enveloped B-coronavirus transmitted via respiratory droplets, attached via viral spike protein to angiotensin-converting enzyme 2 receptor (ACE2 receptor) causing clinical asyndrome of coronavirus disease 2019. Severe covid-19 may progress to develope acute respiratory distress syndrome, cardiovascular complications, shock, and death. Cardiac arrest is often unexpected and acute event may present in every hospitalized patient. Abnormal vital signs can be the predictos of in-hospital cardiac arrest. During the outbreak of covid-19, there were increase reports of in-hospital cardiac arrest (IHCA), out-of hospital cardiac arrest (OHCA), lower rate of successful cardiopulmonary resuscitation (CPR), and increased mortality. 30-days mortality in covid-19 patients was increased 3.4 fold in OHCA and 2.3 fold in IHCA compared with pre-pandemic period. survival of in-hospital cardiac arrest was poor. Factors related to restricted or delay access to emergency care, late presentation of ACS or heart failure in hospital, avoidance of witness CPR in public due to fear contracting covid-19, as well as the side effects of drugs and thrombotic complications related to covid-19 led to higher incidence of cardiac arrest during covid-19 pandemic.

Historical Perspective

  • In December 2019, the COVID-19 outbreak first appeared in China, Wuhan.[1]
  • In January 2020, the first COVID-19 case was documented in the United States.[2]
  • On February 20, 2020, the first case of COVID-19 was documented in the Province of Lodi in Italy.[3]
  • In April 2020, an increase of out-of-hospital cardiac arrest was reported during the COVID-19 pandemic in Italy by Dr.Enrico Baldi.[4]

Classification

Cardiac arrest associated with COVID-19 may be classified into three subtypes:[5]

Causes

The potential causes of ventricular tachyarrhythmia and sudden cardiac death in COVID-19 include:[6]

Natural History, Complications, and Prognosis

Diagnosis

Diagnostic Criteria

  • The diagnosis of sudden cardiac death is made when the following diagnostic criteria are met:
  • Prodromes phase occurring weeks or months before an event includes: new or worsening cardiovascular symptoms(chest pain, dyspnea, palpitations, fatigability)
  • Onset of terminal event occurring one hour before cardiac arrest includes: abrupt change in clinical status(arrhythmia, hypotension, chest pain, dyspnea, lightheadness)
  • Cardiac arrest includes: sudden collapse, loss of effective circulation, loss of consciousness
  • Biologic death: failure of resuscitation or failure of electrical, mechanical, or CNS function after initial resuscitation

Symptoms

Physical Examination

There is no specific finding associated with physical examination with cardiac arrest in COVID-19.

Laboratory Findings

  • An elevated concentration of serum cardiac troponinI was detected in severe COVID-19 patients with cardiac complications. [21]

Imaging Findings

There are no imaging study findings associated with cardiac arrest in COVID-19.

Electrocardiogram


Treatment

  • The mainstay of therapy for COVID-19-related cardiac arrest is cardiopulmonary resuscitation with attention to the following points:[22]
    • Wearing personal protective equipment (PPE) before entering the room or on the scene.
    • Limiting the personnel in the room or on the scene
    • Using high-efficacy particulate air filter for ventilator
    • Intubating with a cuffed tube
    • Stopping chest compression for intubation
    • Using bag-mask device before intubation
    • Using non-rebreathing face mask instead of bag-mask for short term oxygenation

Prevention

Effective measures for the primary prevention of ventricular arrhythmia during using hydroxychloroquine in the setting of long QT syndrome or aquired LQTS or heart rate <50/min or receiving azithromycin, remdesivir, lopinavir, ritonavir, include EKG and QTc measurement.[15]
