Stress (Definition)

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger.

Day 4 heart skipping and palpitation stress test came back good and im not dehydrated what could be wrong? No alcohol, caffeine or drugs. On monitor

If the skip beats and palpitations occur while you are on the monitor then a record is made and your cardiologist should be able to get a better idea of what is going on. Many have ways for you to mark when you have symptoms, too. An electrophysiologist (heart rhythm specialist) should be able to help. ...Read more
