But you're lucky, relatively speaking. If you were shot in the heart, your blood pressure would quickly drop, but it would take 10 to 15 seconds to lose brain function. In that time you could draw your gun, utter last words, or spend some time thinking about your unfortunate situation.
Caffeine can cause indigestion, which in turn may lead to heart palpitations. However, arrhythmia (abnormal heart rhythm) can also cause palpitations, and this condition is more of a concern. Seek medical attention if your palpitations last longer than two or three minutes.
Symptoms & Causes. Indigestion has many symptoms. You may have more than one symptom at the same time. Sometimes you may also have heartburn, which is a separate condition. Lifestyle, medicines, health problems, and digestive tract diseases can cause indigestion. Diagnosis Your doctor diagnoses indigestion based on your medical history, a physical exam, upper gastrointestinal (GI) endoscopy, and other tests.
