Q. Does stress cause heart palpitations?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Yes, stress can indeed cause heart palpitations. When a person is stressed, the adrenal glands release two hormones known as epinephrine and norepinephrine. These hormones increase your heart rate, blood pressure and breathing rate—all of which can lead to palpitation-like symptoms in the chest or throat region. In addition, stress may also lead to an abnormal beating pattern in your heart, called premature atrial contractions (PACs) or premature ventricular contractions (PVCs). PACs/PVCs are extra beats that occur before the normal heartbeat rhythm—resulting in additional chest palpitations or a pause between two regular beats.
It is important to note that while stress is correlated with experiencing excessive heart palpitations, there could be other underlying causes such as anemia; thyroid disorder; cardiac arrhythmias like tachycardia or bradycardia; alcohol use disorder; drug abuse and withdrawal; diabetes complications; dehydration; electrolyte imbalances such as low potassium levels (hypokalemia); certain medications like decongestants and some types of birth control pills ;and more serious health issues like congestive heart failure.
Therefore it is essential for people who experience palpitations more than occasionally to consult their doctor for proper diagnosis and treatment plan. It should also be noted that experiencing occasional palpitations due to momentary bursts of physical activity does not necessarily mean you have an underlying medical condition—it’s perfectly normal!
