All About Tenerife: Why is my heart all of a flutter?

Heart palpitations are heartbeats that suddenly become more noticeable.

Does your heart feel like it is pounding, fluttering or beating irregularly, often for just a few seconds or minutes? You may also feel these sensations in your throat or neck.

Palpitations may seem alarming but in most cases they are harmless and are not a sign of a problem with your heart.
