Depends: Certain drugs and venoms cause reversible or irreversible blockade of acetylcholine receptors. Some cause rapid heart rate. If you're receiving such a drug, it's under the supervision of a physician, so put your trust in that person. Whether the increased heart rate is injurious depends on the specifics of your health history and condition.
