So it must be atrial fibrillation. Answer : it is irregularly irregular and the initial part of the QRS is fast, so this is atrial fibrillation with Left Bundle Branch Block (LBBB). Pacemaker mediated tachycardia! Another ECG was recorded 12 minutes later: Paced rhythm, probable Pacemaker-Mediated Tachycardia ?

BackgroundScreening for atrial fibrillation (AF) may reveal incidental arrhythmias of relevance. Subsequently, 8 patients underwent pacemaker implantation, 1 for sinus node dysfunction (post‐AF conversion pause of 9 seconds) and 7 for advanced AVB.

He had previously undergone non‐contrasted head computed tomography (NCHCT) (magnetic resonance imaging (MRI) was unable to be performed secondary to pacemaker), which did not reveal strokes. Episodes always occurred after activity and only upon sitting. Episodes always occurred after activity and only upon sitting.

Background:Left bundle branch area pacing (LBBAP) may be associated with greater improvement in left ventricular ejection fraction and reduction in death or heart failure hospitalization when compared with biventricular pacing (BVP) in patients requiring cardiac resynchronization therapy (CRT).

Patients use them to observe their heart activity by themselves when they are not in the hospital. Though their accuracy is not as high as a hospital ECG machine, they are very beneficial in detecting problems in any medical emergency and providing information about long-term heart activity.
