Popis:	In patients with chronic atrial fi brillation and congestive heart failure presenting with narrow QRS complex the direct His-bundle pacing the use of dual chamber implantable cardioverter-defibrillator can be a defi nite treatment option meeting all therapeutic goals. This approach enables heart rate regularization, appropriate increase of beta-blocker dose with additional benefi t in terms of arrhythmic death prophylaxis. The proper functioning of implantable cardioverter- -defibrillator demands appropriate atrial channel/His-bundle signal sensing. The low His-bundle electrogram amplitude usually does not interfere with the device function and the DDI or DVI programming modes are reasonable. The authors present a case of unusually high His-bundle signal amplitude sensed by atrial channel of implantable cardioverter-defibrillator, which could potentially contribute to some particular programming considerations. The attending physician should be aware of some arrhythmia discriminators which may delay or even withhold the appropriate shock.
