Management of Severe Bradycardia and Hypotension

Critical Assessment and Immediate Interventions

The American College of Cardiology recommends stopping both lisinopril and amlodipine immediately and administering atropine 0.5 mg IV every 3-5 minutes up to a maximum of 3 mg as first-line treatment for symptomatic bradycardia with wide pulse pressure hypotension 1
The European Heart Journal suggests that a wide pulse pressure of 85 mmHg may indicate possible aortic regurgitation or severe arterial stiffness, and a diastolic BP of 45 mmHg indicates inadequate organ perfusion 2
The combination of lisinopril and amlodipine can cause additive hypotensive effects, and the Journal of the American College of Cardiology documents severe bradycardia and hypotension with ACE inhibitor therapy, particularly in elderly patients 3

The American College of Cardiology recommends discontinuing amlodipine immediately, as calcium channel blockers are specifically contraindicated in hypotension and can worsen bradycardia 3
The European Heart Journal suggests avoiding restarting these medications until hemodynamic stability is achieved and alternative regimens are considered 2
The European Heart Journal recommends establishing IV access and initiating normal saline bolus to address potential volume depletion 5
The American College of Cardiology recommends applying continuous cardiac monitoring with frequent blood pressure checks 6

The American College of Cardiology recommends epinephrine infusion 2-10 mcg/min IV if no response to atropine, and dopamine infusion 5-20 mcg/kg/min IV particularly useful for hypotension with bradycardia 1
The Journal of the American College of Cardiology recommends preparing transcutaneous pacing immediately, and applying pacing patches as standby even if atropine is being administered 4
The Journal of the American College of Cardiology suggests considering calcium chloride 10-20 mL of 10% solution IV to reverse calcium channel blocker effects, and glucagon 3-10 mg IV bolus followed by infusion of 3-5 mg/h for refractory cases 3

The American College of Cardiology recommends continuous ECG monitoring for heart rate and rhythm, and blood pressure every 5-15 minutes until stable 6
The European Heart Journal suggests targeting systolic BP 120-129 mmHg when restarting therapy, but only after resolution of acute episode 2
The European Heart Journal recommends monitoring closely for recurrence if any ACE inhibitor or calcium channel blocker is reintroduced 2
