Characteristic Electrocardiographic Manifestations in Patients With COVID-19

Abstract: Cardiac involvement has been reported in patients with COVID-19, which may be reflected by electrocardiographic (ECG) changes. Two COVID-19 cases in our report exhibited different ECG manifestations as the disease caused deterioration. The first case presented temporary SIQIIITIII morphology followed by reversible nearly complete atrioventricular block, and the second demonstrated ST-segment elevation accompanied by multifocal ventricular tachycardia. The underlying mechanisms of these ECG abnormalities in the… Show more

“…COVID-19 complicated by cardiovascular injury may indirectly be reflected by ECG changes. ECG abnormalities including STsegment elevation and multifocal ventricular tachycardia have been reported in patients with COVID-19 [71]. Also, medications are currently used empirically to treat COVID-19 may have side effects and drug interactions, e.g., chloroquine and hydroxychloroquine are known to prolong the QT interval which can potentially lead to fatal side effects [72].…”

“…Sinus tachycardia is the most common rhythm disturbance reported in patients with COVID-19. Moreover, a variety of other rhythm disorders and electrocardiographic alterations have been reported in patients with COVID-19 such as supraventricular tachycardia [62,63], ventricular tachycardia, first-degree atrioventricular block (AVB), temporary second-degree AVB, reversible complete heart block, generalized STelevation masquerading ST-elevation myocardial infarction (STEMI), triangular-type ST-elevation myocardial infarction type 2, S1Q3T3 pattern mimicking acute pulmonary embolism, non-specific ST and T wave changes, diffuse U waves in the presence of a QTc of 0.45 ms, and pulseless electrical activity [63,75].…”

“…Temporary occurrence of S1Q3T3 and subsequent transient, nearly complete A-V block may reflect transient pulmonary artery hypertension secondary to trachea secretive obstruction, which may cause extensive small pulmonary artery compression [ 29 ]. The development of ST-elevation and ventricular tachycardia can have multiple triggers, such as hypoxia, hydroxychloroquine-induced arrhythmias, among others [ 29 ]. A study carried out by Wang et al reported a 16.7% incidence of arrhythmia, more so in the intensive care unit (ICU) admissions [ 1 ].…”
