Implication
May support four-chamber pacing feasibility in severe HF; leaves open need for controlled trials before adoption.
Structured PICO
Does four chamber pacing improve clinical status and hemodynamics in a patient with severe congestive heart failure and interventricular dyssynchrony?
P
Population
1 adult male (54 years old) with severe congestive heart failure (NYHA functional Class IV), dilated cardiomyopathy, left bundle branch block (200-msec QRS duration), 200-msec PR interval, and 90-msec interatrial interval.
I
Intervention
Four chamber pacing system (permanent bipolar DDD pacemaker with right and left atrial and ventricular leads).
O
Outcome
Clinical status improvement (NYHA functional class, weight loss, peripheral edema).patient reported
Four chamber pacing is technically feasible and can provide marked clinical and hemodynamic improvement in a patient with severe heart failure and interventricular dyssynchrony.
