There doesn't appear to be any problem based on your heart rate. In fact it is quite good. Bradycardia is a measurement below 60 bpm; it would have to drop much more to be a medical problem. A very slow heartbeat can cause clots.
Irregular heartbeat (skipped beat) is quite common according to my echo technician. He attempted to show me one on the screen, but none occurred.
Mild regurg is also quite common. Doesn't require treatment, but should be watched. No need for concern.
A possiblility that due to stress, diet, coffee there is a chemical imbalance (calcium, postassium, electrolytes). The imbalance can interfere with the conduction of electric impulses causing the irregular heartbeats.
