Clinical narrative: arrythmia under control with medication; after second dose patient went into SVT; bruising from her deltoid to the bottom of her latissimus dorsi; anemic; periodic chest pain for a couple of months; This spontaneous case was reported by a physician and describes the occurrence of ARRHYTHMIA (arrythmia under control with medication) in a 38-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 012L20A and 012L20A) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.     No Medical History information was reported.   On an unknown date, the patient received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) dosage was changed to 1 dosage form. On an unknown date, the patient experienced ARRHYTHMIA (arrythmia under control with medication) (seriousness criterion medically significant), SUPRAVENTRICULAR TACHYCARDIA (after second dose patient went into SVT), MUSCLE CONTUSION (bruising from her deltoid to the bottom of her latissimus dorsi), ANAEMIA (anemic) and CHEST PAIN (periodic chest pain for a couple of months). At the time of the report, ARRHYTHMIA (arrythmia under control with medication) was resolving, SUPRAVENTRICULAR TACHYCARDIA (after second dose patient went into SVT), MUSCLE CONTUSION (bruising from her deltoid to the bottom of her latissimus dorsi) and ANAEMIA (anemic) outcome was unknown and CHEST PAIN (periodic chest pain for a couple of months) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, Cardiac stress test: negative (Negative) Negative and negative (Negative) Negative. On an unknown date, Echocardiogram: negative (Negative) Negative.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter did not provide any causality assessments.   No concomitant medications were provided. No treatment medications were provided. There was no diagnosis of myocarditis or pericarditis and no medical history of arrhythmia. Patient had seen a cardiologist.  Company Comment: This case concerns a 38-year-old, female patient with no previous relevant medical history reported, who experienced the unexpected events of arrhythmia and supraventricular tachycardia. The events occurred on an unknown number of days after the second dose of mRNA-1273. The rechallenge was not applicable since the events happened after the second dose. The benefit-risk relationship of mRNA-1273 is not affected by this report.; Sender's Comments: This case concerns a 38-year-old, female patient with no previous relevant medical history reported, who experienced the unexpected events of arrhythmia and supraventricular tachycardia.
