Possible Causes of Fatigue, Palpitations and Rapid Heartbeat

Conditions that commonly produce all three symptoms together

1Early Myocarditis often produces non-specific symptoms: fatigue, malaise, or mild discomfort
2Early warning signs may include: chest pain, shortness of breath, fatigue, palpitations
3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
4Family history and risk factors increase the probability that vague symptoms represent early Myocarditis
5Screening programmes are designed specifically to detect Myocarditis before symptoms appear
6Core management targets: reducing chest pain, shortness of breath, fatigue and preventing disease progression

Strong family history of Myocarditis combined with new relevant symptoms
