    Hi:

    "Blood work has showed nothing"

    Lab tests offer very limited diagnostics.

    Do quit smoking ASAP!

    As reported, smoking increases the circulating levels of catecholamines and free fatty acids, which may contribute to the increased level of total cholesterol and decreased levels of high-density lipoprotein ("good" cholesterol) that are found in habitual cigarette smokers.

    The effects on platelets may enhance coagulation (blood clotting). There can be accelerated coronary and peripheral vascular disease, and occurrence of a dreaded stroke and complications from hypertension.

    The greatest concern is the acceleration or aggravation of cardiovascular disease. Smoking can promote atherosclerotic vascular disease by contributing to high cholesterol, endothelial injury (damaging the sensitive inner lining of the walls of the arteries), or both.

    Complications of hypertension are more severe in those who smoke cigarettes. Smoking can also aggravate hypertension by causing vasoconstriction (tightening of the vessels).

    Just one cigarette can harm DNA, Surgeon General says

    12/9/10

    "Tobacco smoke damages almost every organ in your body," says Surgeon General Regina Benjamin. In someone with underlying heart disease, she says, "One cigarette can cause a heart attack."

    http://www.usatoday.com/yourlife/health/2010-12-09-1Asmoking09_st_N.htm

    Additionlly, as applicable, the most common type of palpitations (premature ventricular contractions, PVCs), which has various causes or triggers, cardiac and non-cardiac in origin, are typically harmless/benign, 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. Various symptoms may/can occur wih PVCs or none at all.

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

    Best of luck down the road of life.
