Q

CHB stable sequence

A

Transcutaneous pads- evaluate for reversibility

non reversible- needs Pace maker

reversible- treat cause

Q

Unstable CHB sequence

A

atropine- transcutaneous pads-

if Low BP–> IV Dopamine

if HF—> IV Dobutamine

normal BP, no HF–> transvenous pacing

when stabilized assess for reversible causes—- none or CHB persists (PPM)

Q

Indication for permanent pacemaker

A

SYMPTOMATIC bradycardias and heart blocks that are NOT reversible or time-limited

Others: Sick sinus syndrome, tachy-brady syndrome, chronic Afib with slow ventricular response, hypersensitive carotid sinus syndrome
