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.
Remember that indigestion is common and it's not usually caused by cancer. It can be very painful, even when there's nothing seriously wrong. See your doctor if youâve had heartburn most days for 3 weeks or more, even if youâre taking medicine and it seems to help.
