QT-COVID-19: Effects on the Qt Interval of COVID-19 Coronavirus Infection
Study Details
Study Description
Brief Summary
The present study aims to evaluate the impact of COVID-19 disease and its treatment on ventricular repolarization, assessed by measuring the QTc interval, in patients admitted to the critical care unit.

Detailed Description
Coronavirus infection of Severe Acute Respiratory Syndrome COVID-2 is characterized by a broad clinical spectrum ranging from asymptomatic infection, mild upper respiratory tract disease and severe viral pneumonia with respiratory failure and even death, with many patients hospitalized with pneumonia. In addition, the infection can have a direct impact on cardiovascular disease including the development of arrhythmias, although the exact incidence is not known. Treatments administered for COVID-19 infection have the potential to produce adverse cardiovascular effects including prolongation of the QT interval and development of arrhythmias.
Relevant clinical data that may affect the QT interval and specifically the medication the patient has received will be recorded. The specific treatment administered for COVID-19 will be recorded as the concomitant medication of the critical patient that may have an impact on the QT interval. Analytical data will also be collected on plasma levels of ions such as potassium, calcium and magnesium, blood gases, renal and hepatic function parameters and cardiac markers.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Critical care patients Patients admitted to critical care units for COVID-19, where ECG records and relevant clinical information are available to assess the impact of the disease and its concomitant treatment on electrocardiographic parameters of ventricular repolarization |
Outcome Measures
Primary Outcome Measures
- Assessing the QT and QTc interval in patients admitted to intensive care units for COVID-19 infection [through study completion, an average of 1 year]
The QT interval measurement will be performed on the available 12-lead ECG from the medical record. The QT interval will be measured according to the recommendations of the scientific societies of cardiology: it is considered from the beginning of the activation of the ventricular myocardium and the end of its repolarization, which are represented in the ECG respectively by the beginning of the QRS and the end of the T wave. Ideally, the QT interval should be measured in Q-wave leads in DII and V5. An average value of 3 heart cycles (beats) should be recorded. Two researchers to control inter-observer variability will perform the measurement.
Secondary Outcome Measures
- incidence of arrhythmias and impact of the COVI-drugs administered on QT interval [through study completion, an average of 1 year]
To assess the incidence of arrhythmias in critically ill patients with COVID-19 infection admitted to critical patient units. To evaluate the impact of the association of drugs administered for the treatment of COVID-19 infection in critically ill patients in the QT interval.
