TO AV SEQUENTIAL PACE 1) Place patient's right wires into the atrial ( blue ) poles Place patient's left wires into the ventricle (white) poles 2) Set the Rate 3) Check the AV interval Fiddling with the pacemaker settings to increase the VA delay will sort this out so the pacemaker ignores the retrograde transmission. Pacemaker syndrome In some patients who are RV paced without an atrial lead, the AV node can conduct retrogradely – this causes dysynchrony between the atria and ventricles and can cause significant mitral and tricuspid regurgitation along with heart failure symptoms.

AV sequential pacing (tracking) At a glance this will seem to be a simple LBBB (left bundle branch block. But the QRS complexes are negative in V5, V6 unlike in a usual LBBB. It is actually AV sequential pacing (tracking). A close scrutiny will reveal the small pacing spikes just before the QRS complexes. You may also hear the term “AV Sequential” which is the same as dual pacemaker. It paces at a programmed rate in the atrium and senses and paces in the ventricle.

AV Sequential Pacing to Ventricular Tachycardia. This is an interesting ECG for showing students AV sequential pacing and also ventricular tachycardia. The unusual thing about this ECG is that the V Tach starts at the time the machine begins recording the precordial leads. This particular ECG machine shows a slight "gap" at the lead change, so we

This is the American ICD-10-CM version of Z95.0 - other international versions of … A-V sequential: Cardiac pacing A dual-chamber pacemaker that paces at a programmed rate in the atrium and senses and paces in the ventricle In this pacing mode, the pacemaker will pace both the atrium and the ventricle (AV sequential pacing), with programmed AV delay if the intrinsic atrial and ventricular rates are below the LRL. If the atrial rate is slower than the LRL, the device will pace the atrium while inhibiting ventricular pacing if an intrinsic ventricular event is sensed within a pre-determined AV delay. Single lead AV sequential pacemakers (VDD) allow AV synchrony and, by virtue of implanting a single lead, can be advantageous when compared with traditional dual lead (DDD) pacemakers. The objective of this retrospective case-controlled study was to compare the strategy of AV sequential pacing with a VDD versus DDD pacemaker in consecutive TAVI patients (n = 120) with acquired AVB. секвенциальный кардиостимулятор We describe pacemaker pauses and pseudohysteresis resulting from sensing of retrograde P waves in a patient with an implanted AV sequential universal pacemaker. Although retrograde P waves are usually followed by a ventricular spike and therefore create the possibility for “endless loop tachycardia,” in our patient some retrograde P waves which followed premature ventricuiar contractions AV sequential pacemakers.

The unusual thing about this ECG is that Dual chamber sequential pacing is contraindicated in patients with chronic or persistent supraventricular tachycardias, including atrial fibrillation or flutter. Temporary atrial and ventricular pacing in the DVI, VVI, and AOO modes using atrioventricular sequential DVI devices is routinely used in Control of a pacemaker as a function of the contractility of the cardious.
