Final answer:
Initial treatment of bradycardia in an acute inferior MI generally involves atropine and possibly a pacemaker, and similar treatments apply for anterior MI. Supplemental oxygen, aspirin, and nitroglycerine are immediate treatments for any type of MI, with further interventions depending on severity and progression.
Step-by-step explanation:
The initial treatment of bradycardia in acute inferior myocardial infarction (MI) often includes atropine to increase heart rate. In cases where atropine is ineffective, a pacemaker may be required. For anterior MI, the treatment for bradycardia also typically begins with atropine; however, due to potentially larger infarctions and possible damage to the conduction system, a pacemaker may be more frequently considered. Immediate treatments for any MI include administering supplemental oxygen, aspirin to help break up blood clots, and nitroglycerine sublingually for its vasodilatory effects. Other longer-term treatments can involve thrombolytic agents, anticoagulants such as heparin, balloon angioplasty, stents, bypass surgery, and in severe cases, heart replacement with a donor heart or a coronary assist device.
