Overview
The sudden cardiac death is defined as the 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 in Italy increased. Prognosis of in-hospital cardiac arrest was generally poor. Factors related to medical services restriction and also side effects of drugs and thrombotic complications related to COVID-19, increased the number of cardiac arrest during COVID-19 pandemic.
Historical Perspective
- In December 2019, the COVID-19 outbreak first appeared in China, Wuhan.[1]
- On February 20, 2020, the first case of COVID-19 was documented in Lodi Province of Italy.[2]
- In April 2020, An increase in out of hospital cardiac arrest was reported during the COVID-19 pandemic.
- In January 2020, the first COVID-19 case was documented in the United States.[3]
Classification
Cardiac arrest associated with COVID19 may be classified into three subtypes:
- Pulseless electrical activity
- Bradyarrhythmia and asystolic arrest
- Fatal tachyarrhythmia
Causes
- The potential causes of ventricular tachyarrhythmia and sudden cardiac death in COVID-19 are:[4]
- Hypercytokinemia
- Administration of drugs causing QT interval prolongation such as hydroxychloroquine ± azithromycin, lopinavir, and ritonavir[5]
- Concurrent use of drugs causing QT interval prolongation, such as antiemetics,floroquinolones,SSRIs
- Electrolyte abnormalities such as hypokalemia and hypomagnesemia
- High-risk comorbidity condition such as Congestive heart failure, chronic kidney disease, diabetes mellitus, and chronic obstructive pulmonary disease
- Age ≥65
- Male gender
- Inherited arrhythmia syndromes
- Increased sympathetic activity
- Inhibition of CYP450
- Direct myocardial injury or SARS-COV-2 myocarditis
- Acute cardiac events (acute coronary syndrome, decompensated heart failure, arrhythmia)
- Thromboembolic events related to COVID-19 (pulmonary embolism, acute coronary syndrome)[6]
- Hypoxia
Pathophysiology
- The pathogenesis of cardiac arrest associated with COVID-19 is characterized by cytokine storm, especially elevation of IL-6.[7]
- IL-6 directely blocks hERG/Kv11.1 potassium channels and causes action potential depolarization(APD) prolongation and ventricular repolarization.
- IL-6 induces hyperactivity of cardiac sympathetic nerve.
- Hypoxia causes myocardial injury and ventricular repolarization.
- IL-6 inhibits cytochrome P450 enzyme involved in matobolism of some QTc prolongation drugs.[8]
- Hydroxychloroquine and lopinavir/ritonavir inhibit HERG-K+ channel and increase both ventriculat repolarization and the level of other QTc prolongation drugs.[8]Hydroxychloroquine inhibits CYP2D6 (cytochrome P450 2D6) ,then the level of antipsychotics,antidepressants and antihistamins increase.[8]
- Ritonavir inhibits CYP3A4 (cytochrome P450 3A4), then the level of azols antifungals, macrolides (particulary azithromycin),antidepressants,antihistamines,fluoroquinolones increase.[8]
- Intrinsic genetic susceptibility (Ser1103Tyr-SCN5A) in african americans COVID-19 patients has been associated with increased risk of torsade points arrhythmia.[9]
Differentiating inherited cardiac arrest from other causes of cardiac arrest.
- To view the differential diagnosis of COVID-19 click here.
- Inherited cardiac arrest associated COVID19 must be differentiated from other causes of cardiac arrest based on these characteristics:[10][11][12][13][14][15][16][17][18]

- Corrected QT(QTc)=1000(QT/1000+0.154(1-RR)
- RR is measured in seconds and is the interval from the onset of one QRS complex to the onset of the next QRS complex.
Epidemiology and Demographics
Incidence
- There is a two-times rise in the incidence of Out of hospital Sudden cardiac arrest (OHCA) during the COVID-19 pandemic as compared to the non-pandemic time period.
- According to a study done in China, about 12% of patients with COVID-19 without a history of heart problems experience cardiac arrest during their hospitalization.[19]
- In a study done among 761 Chinese patients with severe COVID-19, about 20% patients developed in-hospital cardiac arrest within 40 days of their hospitalization course.[20]
Mortality
- There is a significant increase in the mortality rate of the OHCA in patients.[21]
Age
- Mean age 69.7 years is observed among patients who experienced Out of hospital Sudden cardiac arrest (OHCA) .[21] .
Gender
- Studies showed that male gender have a slightly higher incidence of Out of hospital sudden cardiac arrest (OHCA) as compared to the females.[21]
Race
A higher incidence has been seen among African-Americans as compared to the Caucasians.[22]
Risk Factors
- Common risk factors in the development of arrhythmia and cardiac arrest in COVID-19 are:[23]
- Fever
- Stress
- Electrolytes disturbances
- Use of some medications
Screening
- To view screening for COVID-19, click here.
Natural History, Complications, and Prognosis
- The proportion of patients developed out of hospital cardiac arrest (OHCA) increased during covid-19 pandemic.[24]and was affected by aggravation of underlying comorbidities, late presentation of acute STEMI due to fear of being infected in hospital and avoidance of bystander cardiopulmonary resuscitation in public due to fear of infection.[25][26]
- Prognosis of patients with severe COVID-19 pneumonia with in hospital cardiac arrest (IHCA) was poor in wohan .[27]
Diagnosis
Diagnostic Criteria
- The diagnosis of sudden cardiac death is made when the following diagnostic criteria are met:
- Prodromes phase occuring weeks or months before an event includes: new or worsening cardiovascular symptoms(chest pain, dyspnea, palpitations, fatigability)
- Onset of terminal event occuring 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 electerical, mechanical or CNS function after initial resuscitation
Symptoms
- Symptoms before cardiac arrest in covid19 may include the following:
- Chest pain
- Palpitation
- Dyspnea
- Lightheadness
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. [29]
Imaging Findings
- There are no imaging study findings associated with cardiac arrest in COVID-19.
Electrocardiogram
- Findings on EKG during inhospital cardiac arrest(IHCA) in covid19 include:asystole(89.7%),pulseless electrical activity(4.4%) shockable rhythm(5.9%)[27]
- Other abnormal EKG findings include QT prolongation. ECG shows corrected QT interval (QTc) more than 500 ms.
Treatment
- The mainstay of therapy for cardiac arrest in COVID-19 is cardiopulmonary rescucitation with attention to the following points:[30]
- 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
- Intubatting with a cuffed tube
- Stopping chest compression for intubation
- Using bag-mask device before intubation
- Using nonrebreathing 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 recieving azithromycin,redmisivir, lopinavir, ritonavir, include EKG and QTc measurement.[23]
- If QTc ≥500 ms, consult with cardiologist.
- If QTc<500ms, start hydroxychloroquine and repeat EKG after 1-3 days.
- After starting the first dose of hydroxychloroquine, If any of the following factors were present repeat EKG after 4 hours:
- QTc≥500mse
- Increased QTc>60ms
- Ventricular ectopy
- Treatment of hypokalemia due to diarrhea associated COVID-19 ,which prolonges QT interval is another measurement to be considered.
- Effective measures for the primary prevention of ventricular arrhythmia in brugada syndrome is starting acetaminophen or parastamol immediately if there is sign of fever and also self-isolation.
