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?

The rhythm is uncertain ( ie, We only see 4 beats — because the same 4 beats are repeated in limb and chest leads — but in lead II there appears to be sinus bradycardia and arrhythmia plus a P wave with a PR interval too short to conduct preceding beat #1 — therefore need for a longer period of monitoring ).

Athlete’s bradycardia due to increased parasympathetic tone and decreased sympathetic tone is a well-known observation. Though sinus bradycardia is usual, other abnormalities like sinus arrhythmia, sinus arrest, wandering atrial pacemaker and coronary sinus rhythm have been described. 2012 Jun;98(12):947-55.

Use of drugs producing bradycardia like beta blockers in stages III and IV may precipitate low output state. 2012; 126: 138-141. 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.
