I get random shortness of breath/like my heart skips a beat. it happens at random times i could be doing something i could b resting what is this?

Palpitation: It sounds like an early extra heart beat causing the sensation of a skipped beat. An event monitor can be worn to help figure out the exact type of heart rhythm associated with these symptoms.

Need a monitor: Your symptoms are most likely related to an irregularity in the heart (cardiac) rhythm. The kind of symptom complex you describe may be associated with a benign cardiac rhythm disturbance, like single premature beats, but it may also be associated with a more significant arrhythmia. A 24 hour cardiac monitor would be helpful in determining the cause of your spells.
