Cardiovascular – Palpitations or racing heart rate, chest pain

CNS findings on physical examination include the following:
Anxiety, agitation
Tremors
Seizures

Hypotension
Tachypnea
GI findings on physical examination include the following:
Vomiting

~~~~~Energy drinks may increase heart malfunction, high blood pressure risk.
Taking in energy drinks too quickly may disturb electrical activity in the body, potentially bringing on irregular heart rhythms and high blood pressure, a new study says.
Consuming a 32-ounce energy drink can create heart abnormalities and raise blood pressure compared to drinking a non-energy beverage, according to a small study published in the June edition of the Journal of the American Heart Association.
