stimulate the atrium at frequencies faster than the intrinsic atrial frequency (overdrive).<\/p><p>When the algorithm detects two P waves within a 16-cycle window, the device increases the pacing frequency to neutralize spontaneous conduction. After pacing at the AF Suppression frequency for the number of cycles indicated by the Number of overdrive cycles parameter (15 to 40; nominal 15), the device slows down its frequency until it detects two new P waves. If two P waves are not detected, stimulation resumes according to the setting for base frequency, rest frequency or sensor frequency.<\/p><p>Calculation of the overdrive frequency: for simulation frequencies &lt;59 bpm, the overdrive applied is fixed at 10 bpm (=minimum overdrive frequency); for frequencies &gt;151 bpm, fixed overdrive of 5 bpm (=maximum overdrive frequency); for frequencies between 60 and 150 bpm, the AF Suppression algorithm increases the stimulation frequency by a delta between the minimum overdrive frequency and the maximum overdrive frequency.<\/p><p>Return to base frequency: this non-programmable parameter determines the interval and slope of reduction from the overdrive frequency to the base frequency, resting frequency or frequency indicated by the sensor; if the overdrive frequency is greater than 100 bpm, 8ms are added to each cycle up to 100 bpm, then + 12ms to the base frequency.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element

In the absence of a detected event, the pacing rate is progressively reduced (VA interval increased by 10ms).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-24c2081 elementor-widget elementor-widget-image\" data-id=\"24c2081\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"http:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa3.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"pm_19_situations_arythmies_fa3\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NjY4OCwidXJsIjoiaHR0cHM6XC9cL2NhcmRpb2Nhc2VzLmNvbVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyNlwvMDFcL3BtXzE5X3NpdHVhdGlvbnNfYXJ5dGhtaWVzX2ZhMy5wbmcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"537\" height=\"226\" src=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa3.png\" class=\"attachment-large size-large wp-image-6688\" alt=\"\" srcset=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa3.png 537w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa3-300x126.png 300w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa3-18x8.png 18w\" sizes=\"(max-width: 537px) 100vw, 537px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-364fd2d elementor-widget elementor-widget-text-editor\" data-id=\"364fd2d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h6>APP\/ProACt<\/h6><p>This algorithm makes it possible to increase the stimulation frequency following a PAC in order to avoid the succession of short and long cycles.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-43f2273 elementor-widget elementor-widget-image\" data-id=\"43f2273\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"http:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa4.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"pm_19_situations_arythmies_fa4\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NjY4NywidXJsIjoiaHR0cHM6XC9cL2NhcmRpb2Nhc2VzLmNvbVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyNlwvMDFcL3BtXzE5X3NpdHVhdGlvbnNfYXJ5dGhtaWVzX2ZhNC5wbmcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"603\" height=\"309\" src=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa4.png\" class=\"attachment-large size-large wp-image-6687\" alt=\"\" srcset=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa4.png 603w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa4-300x154.png 300w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa4-18x9.png 18w\" sizes=\"(max-width: 603px) 100vw, 603px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c64171 elementor-widget elementor-widget-text-editor\" data-id=\"6c64171\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Following an PAC, the ProAct algorithm calculates 75% of the VV interval preceding the PAC and applies this interval to the next cycle in order to favor atrial pacing.

Atrial pacing pulses delivered for APP are annotated PP (proactive pacing) on the event marker.<\/p><p>If the next atrial event is another non-refractory event detected, the pacing interval is decremented again. This progression continues until the pacing rate exceeds the spontaneous rate, resulting in a stimulated atrial rhythm. However, the value of the programmed maximum frequency provides a frequency limit for atrial pacing preference. After a programmable period of 100% atrial pacing, the stimulator gradually decreases the pacing frequency in search of the next spontaneous beat. The next sinus beat restarts the pacing preference.<\/p><h6>Atrial rhythm stabilization<\/h6><p>Atrial rhythm stabilization (ARS) is a programmable function designed to avoid the sinus pause that follows an PAC (short-long-short cycle sequences that can lead to the abrupt onset of certain atrial tachyarrhythmias). It reacts to an PAC by instantly raising the atrial pacing frequency, then steadily slowing it down to the spontaneous frequency, the programmed pacing frequency or the sensor frequency.<\/p><p>When the device is activated by an PAC, it delivers a pacing pulse at the premature interval increased by a percentage of this interval (defined by the parameter Interval increment in programmed percentage). For each subsequent stimulated or detected atrial event, the device continues to increase each pacing interval by the programmed percentage of the previous interval. The maximum frequency parameter defines a limit for ARS.

algorithm authorizes rate acceleration (~ 5 min-1) temporarily (24 cycles) following frequent isolated atrial extrasystoles (separated by a maximum of 15 normal atrial cycles). By default, this algorithm is inactive. The acceleration phase is stopped if the maximum acceleration frequency is reached or if the maximum PAC counter is reached. These two stop criteria are non-programmable. This stop is followed by a \u201cfinal\u201d smoothing down to the base frequency.<\/p><p>The maximum acceleration rate is calculated as follows: if the atrial rate is below 90 min-1, the escape interval is 75% of the average of the last eight P-P intervals just before the first PAC. Otherwise, the escape interval is 75% of the average of the last eight P-P intervals just before the first PAC + 50 ms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f3c5835 elementor-widget elementor-widget-image\" data-id=\"f3c5835\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"http:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa16.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"pm_19_situations_arythmies_fa16\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NjY3NSwidXJsIjoiaHR0cHM6XC9cL2NhcmRpb2Nhc2VzLmNvbVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyNlwvMDFcL3BtXzE5X3NpdHVhdGlvbnNfYXJ5dGhtaWVzX2ZhMTYucG5nIn0%3D\">\n\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"661\" height=\"595\" src=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa16.png\" class=\"attachment-large size-large wp-image-6675\" alt=\"\" srcset=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa16.png 661w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa16-300x270.png 300w, https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/01\/pm_19_situations_arythmies_fa16-13x12.png 13w\" sizes=\"(max-width: 661px) 100vw, 661px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>AF prevention algorithms Content Certain algorithms have been developed by different manufacturers to reduce the burden of atrial arrhythmia.
