Inappropriate Sinus Tachycardia Following Viral Illness

Abstract

A 67-year-old female patient with a past medical history of menopause, migraines, and gastro-esophageal disease presented with palpitation, fatigue, and shortness of breath. One month prior to her presentation, she reported having flu-like symptoms. Her EKG showed sinus tachycardia with no other abnormality. Laboratory findings, along with imaging, showed normal results. The event monitor failed to detect any arrythmias. We report a case of inappropriate sinus tachycardia secondary to viral infection as a diagnosis of exclusion.

Taquicardia sinusal: Caso clínico

“…A si mismo un usuario de 67 años sexo femenino en un Estudio en EE.UU manifestó una taquicardia sinusal luego de haber presentado infección viral semanas atrás, se le diagnostico mediante el electrocardiograma la TS, el método de diagnóstico que más se utiliza el ECG (32).…”

Targeted Treatment of Inappropriate Sinoatrial Node Tachycardia Based on Electrophysiological and Structural Mechanisms

“…An association between viral illnesses (including SARS-CoV-2 infection) and IST has been described. 36,37 Furthermore, IST has been observed in noninfectious inflammatory diseases such as multiple sclerosis; notably, tachycardia subsided after intravenous methylprednisolone bolus. 38 The link between inflammation and IST is complex and not elucidated fully.…”

Post-COVID-19 Inappropriate Sinus Tachycardia Treated with Naja tripudians: A Case Report

“…The ECG in IST shows increased heart rate, normal P with morphology similar to sinus rhythm, normal qrs complex and T wave with normal ST segment. 9 As treatment of IST is challenging, the initial medical treatment involves prescribing long-term β-blockers but β-blockers can sometimes be ineffective even in high doses. Ivabradine may be the another drug of choice, but it may cause excessive bradycardia.…”

“…7 IST, also called non-paroxysmal sinus tachycardia, is a clinical condition characterised by an elevated resting heart rate of more than 100 beats per minute associated with disturbing palpitations and/or minimal activity that can accelerate it quickly. 9 The palpitations and tachycardia associated with IST are very disturbing for patients. Besides tachycardia, this condition may be associated with fatigue, dizziness or poor exercise tolerance.…”
