Even if we stopped here — We could conclude the following: There is marked bradycardia in today's rhythm ( ie, Heart rate in the low 30s ). Finally — If today's patient does not have significant underlying coronary disease — then her bradycardia with AV block may be the result of SSS ( S ick S inus S yndrome ).

Looking first at the long-lead II rhythm strip — there is significant bradycardia , with a heart R ate just under 40/minute. But the point to emphasize — is that it should only take seconds to recognize that there is bradycardia from significant AV block. = Would you approve her for a nonemergent surgical procedure?

That said — obvious findings include: i ) Marked bradycardia! — Section 2F ( 6 pages = the " short " Answer ) from my ECG-2014 Pocket Brain book provides quick written review of the AV Blocks. The rhythm in Figure-1 is complex — and defies precise interpretation without careful study. be regular! —

Use of drugs producing bradycardia like beta blockers in stages III and IV may precipitate low output state. 2014 May-Jun;66(3):392-3. In stage IV, this restrictive filling pattern remains fixed even during Valsalva maneuver. Initial stages (I to III) are considered reversible with treatment. Stage IV is considered as advanced.

Whatever today's rhythm turns out to be — the "good news" is that the bradycardia and degree of AV block is likely to improve as soon as there is reperfusion of the "culprit" artery ( Therefore need for prompt cath with PCI ).
