Yes, it sounds like you may have a problem with your heart rhythm which could be related directly or indirectly to your low blood pressure. A pulse of 46 is quite low and suggests the possibility that there is a partial blockage in the electrical system in your heart. The palpitations may be related to your heart trying to compensate for the blockage by using an alternate rhythm generator-like something called atrioventricular block with a junctional or ventricular response. Get an EKG done soon and see if that or some other rhythm disturbance is the cause. You might also need what's called a Holder monitor or event monitor. This records your heart beat over time and can detect abnormal rhythms that may only be occurring occasionally. A certain type of nerve condition can also be associated with low blood pressure and heart palpitations. Other tests may be necessary to diagnose this. See a cardiologist and get this evaluated. Hope this helps.
