If a medication or a medical condition is the cause of constipation, eliminating the offending medication or treating the underlying medical condition may relieve the constipation. However, certain conditions require the use of a medication despite its side effects.
Your heartbeat can be either tachycardic or bradycardic during a heart attack, so no i don't believe you had have a normal pulse rate at the time of a heart attack, normal being around 60-70 beats per minute for an adult. Heart rate does decrease though with age but that doesn't necessarily indicate anything is amiss.
Is it possible to have a normal pulse rate during a heart attack? I am an early 50's athletic individual who takes cholesterol lowering meds as I have a history of high cholesterol and a family history of heart attack. This morning I got real dizzy and my left arm felt a certain numbness.
