[Verse 1] Bypass is over but the circuit ain't settled, Junctional tachycardia creeping, metal on metal, One in ten kids feel that narrow QRS sprinting, Faster than the atrium, dissociation hinting. Stitch line sits close to the node's own backyard, VSD patch rubbing where the conduction runs hard, Inflammation simmers, catecholamines are screaming, Low magnesium whispers while the ventricle's dreaming. Cool the core down, dial the drips back slow, Pacing overdrive steady so the rate don't blow, Watch the monitor ladder, AV marching apart, JET's the storm that follows a stressed little heart. [Chorus] J for Junctional, racing hot and tight, A for Atrial, scars sparking in the night, V for Ventricle, scarred ground gone wrong, C for Complete block, silence in the song — JAVC on the strip, that's the rhythm code we read, Four ways the beat can break after the chest can bleed. [Verse 2] Now the atrium's got its own kind of scheming, Atriotomy line, old cannula seaming, Stretch marks from TR, the wall's overfilled, Diuretic flushing potassium, electrolytes spilled. Flutter waves sawtooth, ectopic beats skipping, Atrium's a patchwork quilt, every seam ripping, Watch the sodium, watch the fluid you pull, An irritated chamber don't rest when it's full. [Verse 3] Deeper down the muscle, old scar holds a grudge, Ventricular tachycardia won't budge, Born from ischemic ground or a patch gone fibrotic, Wide QRS warning, rhythm turns psychotic. Long QRS duration, LV squeezing weak, History of VT means the danger's not unique, Before you send them home, call electrophysiology in, ICD conversation — don't let silence begin. [Verse 4] Bundle of His rides the posteroinferior rim, Baffle near the LVOT, revision risks him, Cut too close, complete block drops the floor, Atrium's firing lonely, ventricle ignores. Temporary wires humming till the tissue heals its scar, Drugs and pacing chapter tells you how far, Isoproterenol bridges till the rhythm's restored, Patience and a pacemaker — that's the postop accord. [Bridge] Telemetry's the watchtower, never shut your eyes, Every beat's a message underneath the surgical skies, Magnesium, potassium, keep the currents clean, Read the strip like scripture — see what can't be seen. [Chorus] J for Junctional, racing hot and tight, A for Atrial, scars sparking in the night, V for Ventricle, scarred ground gone wrong, C for Complete block, silence in the song — JAVC on the strip, that's the rhythm code we read, Four ways the beat can break after the chest can bleed. [Outro] Four letters, one chest, a conduction system's test, Catch the rhythm early, give the healing heart its rest.
