Bradyphrenia is a neurological term referring to the slowness of thought common to many disorders of the brain.
Bradycardia (slow heartbeat) means that your heart rate is slower than 60 beats per minute, either occasionally or all the time. For some people (like athletes) a slow heart rate might be normal. In others, it may be dangerous. If you are not taking medications that slow your heart rate down, bradycardia may be caused by a blockage somewhere along the heartâs electrical pathway. Medications commonly used for high blood pressure may include including both drugs used to treat high blood pressure and/or arrhythmias.
