Heavy heartbeat is seen in anemic patients. Also those with high blood pressure
demonstrate a strong heartbeat.
Since the rate is just 72/min it is less possible due to anemia
or could be in recovery stage. Not to worry. Get your blood pressure checked as soon as possible.
Also stress can cause feeling of heavy heartbeat. Do deep breathing exercise
4-5 times a day. Do Yoga for stress relief.
Eat a healthy diet. Drink 102 litres of water daily. Avoid smoking
and drinking alcohol.
Wishing good health.
