Final answer:
The primary treatments for bradycardia with low blood pressure are medication to increase heart rate and pacemaker implantation for restoring regular heart rhythm.
Step-by-step explanation:
The first and second treatments for bradycardia with low blood pressure are generally medication and pacemaker implantation. Initial management often includes medication to increase heart rate, such as atropine or dopamine, which can be particularly effective if the bradycardia is caused by vagal stimulation or certain medications like beta blockers. If the bradycardia persists or is due to intrinsic heart disease, a pacemaker might be necessary. Pacemakers are devices that send electrical impulses to the heart to maintain a regular heartbeat. While fluid resuscitation may be useful if the low blood pressure is due to dehydration or blood loss, it is not a direct treatment for bradycardia unless the bradycardia is the result of hypovolemia. Electrical cardioversion is typically reserved for severe arrhythmias where immediate rhythm restoration is critical, and is not a standard treatment for bradycardia.
