    Hi:

    The most common type of palpitations, premature ventricular contractions (PVCs, occurs even in many heart-healthy individuals), described that the heart is flip-flopping, fluttering, jumping, pausing or stopping briefly (though it's actually not doing that), pounding, skipping, thumping, or strong, hard, or forceful beats being felt in the chest, neck, throat, has various causes (cardiac and non-cardiac) or triggers.

    PVCs, are typically harmless, be it isolated (single), couplets (2-in-row), triplets (3-in-a-row) or salvos (short bursts of 3 or more in-a-row), bigeminy (occurring every other beat), trigeminy (occurring every third beat), quadrigeminy (occurring every fourth beat), etc., etc.

    However, the main problem or concern (even more so, much more emphasized for those with certain major or serious heart conditions) with PVCs is when sustained ventricular tachycardia (runs of PVCs over 30 seconds) occurs.

    Symptoms that may/can occur with PVCs includes none at all or chest pain/discomfort/pressure/tightness, difficulty breathing, lightheadedness or dizziness, and in uncommon to rare cases, near-syncope or syncope (temporary loss of consciousness, includes fainting and passing out).

    Additionally, of the various types/kinds of heart conditions, symptoms may/can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic, such as an irregular or erratic heartbeat, requiring the use of a Holter monitor or event recorder at home and during daily activities) or even be silent.

    Best of luck down the road of life.

    Take care,

    PVC's are generally not cause for concern unless a person is very symptomatic or their PVC's are associated with a structural heart abnormality, such as reduced heart function. In rare cases, very frequent PVC's can be associated with a decline in heart function, so follow-up with your doctor is appropriate if symptoms persist and are very frequent.
