Yes: These sound most like discontinuation symptoms (when one suddenly stops a medicine without tapering the dose). Rapid heart rate (tachycardia) can occur in some individuals during regular therapy with venlafaxine (effexor). Headache is also a common side effect of effexor.

Rapid heart beat: One of the adverse effects of Effexor (venlafaxine) is rapid irregular heart beat- if you have these symptoms consistently, see your doctor immediately.
