Possible Causes of Palpitations and Rapid Heartbeat

Conditions that commonly cause both 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
