Been having irregular heartbeat frequently?

Get checked: This could be normal response to anxiety, caffeine etc, but an irregular heart beat and/or palpitations can be early warning sign of a heart problem or reaction to other serious illness. A physician will need to know more about your history, medications, onset of irregularity and frequency and associated symptoms such as sweating, shortness of breath, weakness, dizziness, anxiety etc.

Many causes: Your heartbeat is meant to be regular but there are many things that make it feel like it is missing, skipping, or fluttering. Most are benign but it is reasonable to see your GP and get an ECG to diagnose the problem if one actually exists.
