Hi there. Thanks for writing in. I am a qualified and certified cardiologist. I read your question with diligence. Palpitations, usually signifies (abnormal) awareness of ones own heart beat. It can be normal heart rate
and rhythm. It could be your heart is beating out of rhythm (Arrhythmias), it can also be due to volume overload due to leakage in valve which echocardiography
will rule out. Further investigations like EKG, Holter, cardiology consult may be necessary to pin point the diagnosis. Please mentions everything regarding palpitation to the doctor, whether it is regular or irregular. If it is episodic how long an episode lasts, does it begin suddenly like bolt from blue and then end as abruptly as it begun and any other symptoms like feeling lightheaded or desire to go for passing urine after an episode. Good Luck.
With Best Wishes
