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.
1 Measuring pulse rate does not indicate high or low blood pressure. 2  For people with high blood pressure, there's no substitute for measuring blood pressure. 3  A rising heart rate does not cause your blood pressure to increase at the same rate.
