The pr interval
Webb11 juni 2024 · The PR interval on the electrocardiogram (ECG) normally shortens with increasing heart rate (HR). The case of a patient with COVID-19 manifesting Mobitz type 1 atrioventricular (AV) block that normalized as the patient’s condition improved prompted us to investigate PR interval behavior in patients with COVID-19. Objective WebbAtrioventricular nodal reentrant tachycardia (AVNRT) is a common tachyarrhythmia occurring in all age groups, from children to elderly. AVNRT is common also among …
