Acute decompensated HF complicated by atrial fibrillation with rapid ventricular response
Encounter flow
12/12 authoredCanonical 12-phase frame with authored status for this dossier.
Frame
Composite engine: ADHF + AF-RVR mutually amplify (loss of atrial kick + tachycardia-mediated reduced diastolic filling vs atrial stretch + neurohormonal activation); both engines must run; route to cardio.acute-hf.core.v1 for decongestion + cardio.afib.core.v1 for chronic rate/rhythm/AC
composite physiology confirmed
Patient inputs (15)
Hyperthyroidism is classic reversible AF precipitant — must screen at first presentation
Age drives CHA₂DS₂-VASc stroke risk + DOAC dose adjustment + lenient vs strict rate target
Defines RVR (≥110 bpm); rate target lenient <110 per RACE II if EF preserved + asymptomatic; strict <80 if symptomatic
eGFR for DOAC dose (apixaban 2.5 BID if 2 of 3 criteria; dabigatran avoid <30); diuretic dosing
Goal K ≥4 to suppress AF; MRA + ARNI dosing risk; arrhythmogenic if low
Goal Mg ≥2 to suppress AF; empiric repletion in decompensation
On AC vs not changes DCCV strategy + bleed risk; check INR if warfarin, last DOAC dose timing
EF stratifies drug choice — diltiazem relatively contraindicated in HFrEF; digoxin + metoprolol preferred; LA size for ablation candidacy per CASTLE-AF
12-lead confirms AF-RVR (irregularly irregular without P waves), excludes flutter, screens for ischemic ECG as composite precipitant
Confirms HF component + decongestion target; trended to assess response
Ischemia as composite precipitant; demand ischemia from RVR can drive type-2 NSTEMI
HD-unstable (SBP <90 + AF-RVR) → STAT DCCV per ACC/AHA 2024 Class I; SCAI staging if persistent
Hypoxia from pulmonary edema + tachycardia-mediated reduced filling; NIPPV indication per 3CPO
Beyond AF — thyroid, ischemia, infection, NSAID, EtOH, non-adherence drive co-management
Stroke risk stratification — nearly always ≥2 in HF cohort (HF=+1, age≥65=+1-2); drives DOAC initiation
* = hard-required. Engine cannot meaningfully run until these are filled.

outpatientSubjective
- Possible entry pathways: ADHF presentation + AF on ECG with HR ≥110 bpm — composite engine activates; Known HF patient + new AF-RVR (HR ≥110) on 12-lead ECG → mutually-amplifying decompensation; Elevated NT-proBNP for age + AF-RVR — composite physiology (loss of atrial kick + tachycardia-mediated).
Objective
- No vitals, labs, or imaging entered for this encounter.

Phenotype framing: Stratify by EF — HFrEF (EF <40) vs HFmrEF (40-49) vs HFpEF (≥50) drives drug choice (diltiazem avoided in HFrEF; digoxin + metoprolol preferred); LA size + AF duration drive ablation candidacy per CASTLE-AF Scope: Composite engine: ADHF + AF-RVR mutually amplify (loss of atrial kick + tachycardia-mediated reduced diastolic filling vs atrial stretch + neurohormonal activation); both engines must run; route to cardio.acute-hf.core.v1 for decongestion + cardio.afib.core.v1 for chronic rate/rhythm/AC No severity triggers fired against current inputs.

Monitoring
Regimen monitoring: - continuous telemetry during rate control and post dccv - serial k mg q12h during diuresis to keep k 4 mg 2 - daily bmp during diuresis - nt probnp trend to assess decongestion - tsh at baseline and 4 weeks if abnormal - doac adherence check at 1 week and 4 weeks - echo at 3 months to reassess ef for icd eligibility Setting (outpatient) monitoring: - Quarterly + annual EF + lipid + AF burden Follow-up plan: Cardiology + EP at 1 week per STRONG-HF; ablation candidacy assessment per CASTLE-AF (consider after compensated, especially HFrEF); chronic AC continuation; chronic GDMT up-titration; thyroid follow-up if abnormal - Close-out criterion: AC continued + cardiology + EP + thyroid follow-up booked + ablation referral if HFrEF + persistent AF Monitoring phase: Continuous telemetry; daily weight, I/O, BMP q24h with K + Mg repletion; NT-proBNP trend; HR target lenient <110 per RACE II if asymptomatic; INR or DOAC adherence; TSH trend if hyperthyroid
Disposition
Current setting: outpatient — Long-term cardiology + EP surveillance: DOAC continuation, GDMT maintenance, ablation completion if pursued, ICD eligibility re-evaluation at 90 days, secondary prevention Disposition criteria: - Long-term continuation; hand off to cardio.hf.core.v1 + cardio.afib.core.v1 chronic engines Escalation triggers (move to higher acuity): - AF burden increasing despite ablation → repeat ablation evaluation - GDMT intolerance → adjust per kidney/K trajectory - Bleeding on DOAC → reverse + reassess CHA₂DS₂-VASc vs HAS-BLED
