<p>Method for avoiding the detection of a far-field QRS by the atrial detector of a heart pacemaker or ICD while allowing the detection of true atrial signal to maximum possible extent; the method comprising generating a Short Atrial Refractory Period (SARP) following an atrial sensed or paced event by means of a SARP timer, blanking of the atrial detector following a ventricular paced event, generating a Post Ventricular Short Atrial Refractory Period (PVSARP) following a ventricular sensed or paced event by means of a PVSARP timer, generating a temporary decrease in the sensivity of amplifier for the atrial signal for a time period following the elapse of the mentioned PVSARP, gradually increasing the sensivity of the amplifier for the atrial signal after said time period.</p> |
