  6. 6. Indication for CRT in patients with permanent AF Class Level 1) Patients with HF, wide QRS and reduced LVEF: 1A) should be considered in chronic HF patients, intrinsic QRS ≥120 ms and LVEF ≤35% who remain in NYHA functional class III and ambulatory IV despite adequate medical treatment (d ), provided that a biventricular pacing as close to 100% as possible can be achieved IIa B 1B) AV junction ablation should be added in case of incomplete biventricular pacing IIa B 2) Patients with uncontrolled heart rate who are candidates for AV junction ablation. CRT should be considered in patients with reduced LVEF who are candidates for AV junction ablation for rate control. IIa B Eur Heart J 2013; 34: 2281-2329

  28. 28. Atrial arrhythmias • Atrial arrhythmias are commonly observed in patients with severe heart failure • Major hemodynamic consequences in CRT patients due to the loss of atrial contribution to cardiac output and loss of biventricular capture in case of ventricular rapid rate
  29. 29. Arrythmias • Loss of biventricular capture due to – Atrial arrhythmias • Specific algorithm to overdrive • Consider AV node ablation
  30. 30. Importance of AV node ablation
  31. 31. Upper rate programming • Some CRT patients have normal SR and AV conduction with during exercise rapid atrial rate • Programming a too low maximal tracking rate may result in pacemaker Wenckebach or 2:1 with the loss of biventricular capture • MTR: 70% of (220 – age) bpm and not nominal 120 bpm!!

  35. 35. Chronotropic incompetence CO = HR X SV  Lack of increase in HR will result in HF pts with reduced LVEF in a lack of increase in CO at exercise  Assessment of the profile of HR during exercise is of major importance  If chronotropic incompetence: program the rate response algorithm
  36. 36. Importance of the exercise test • Usually the device programming is performed at rest, but the assessment of the functioning of the device should be performed also systematically during exercise • Reasons of disappearance of biventricular capture: - loss of atrial sensing - frequent PVCs - Atrial tachyarrhythmias - NSVT or SVT - Spontaneous AV conduction more rapid than the programmed AV delay….
