“… 3 This is the putative mechanism whereby ablation of the slow pathway leads to shortening of the fast pathway effective refractory period independent of autonomic tone, 2 , 3 , 4 and improvement in fast pathway conduction velocity has also been described. 1 , 5 In the series from Natale and colleagues, 1 patients with AV nodal reentrant tachycardia (AVNRT) and a baseline prolonged PR had an average PR interval shortening after slow pathway radiofrequency (RF) ablation of around 70 ms with a maximal shortening of 140 ms, much less than the 255 ms shortening seen in our case. One group found a marked and immediate improvement of baseline PR interval after slow pathway RF ablation in 2 patients with AVNRT; however, the authors concluded that baseline conduction was occurring over the slow pathway.…”

“…The retrieved 17 cases of PPMS—including our case report—are outlined in Table 1 2,6,10,12–21 . Most (88.2%) were adults with an average age of 47 years ranging from 13 to 86 years old.…”

“…Finally, it's worth noting that Lader et al. use the term “slow pathway modification” instead of “slow pathway ablation” in their case 12 . In this context, we harmonized the word “modification” to be synonymous with “ablation.”…”

Pseudo‐pacemaker syndrome (PPMS) is a rare complication of first‐degree atrio‐ventricular (AV) block in which a very prolonged PR interval causes AV dyssynchrony and subsequent symptoms of hemodynamic instability in the absence of an implanted pacemaker. The aim of this manuscript was to describe a unique case of PPMS and to provide a comprehensive review of the topic to help clinicians in the diagnosis and management of this condition. Through systematic research on PubMed, Google Scholar, EBSCO, and Ovid MEDLINE and using the search strings “pseudo‐pacemaker syndrome” and “symptomatic first‐degree AV block,” we identified 14 articles accounting for 17 cases of PPMS, including our case report. The most common age group for PPMS was middle‐aged and young adults, with an average age of 47 years. Palpitations were the most common presenting symptom and four main etiologies of PPMS were identified, as follows: (1) Idiopathic PPMS with evidence of impaired conduction over the AV node (20% of cases), (2) PPMS associated with reversable inflammatory causes (13%) or (3) associated with iatrogenic surgical or interventional procedures leading to the permanent damage of the normal AV conduction system (20%), and, finally, (4) PPM related to dual AV nodal physiology (DAVNP) as a primary finding (27%) or occurring after fast or slow pathway ablation for treatment of AV nodal re‐entrant tachycardia (AVNRT) (20%). Treatment should be patient‐tailored and based on the specific etiology once identified. However, the treatment of PPMS due to DAVNP without AVNRT presentation is yet to be clarified.

“…After documenting in the EP lab that there is only sinus rhythm, the leads were placed again from the torso on to the limb leads and those 'flutter' waves were reproduced [15,16]! mind, if the fast pathway is unintentionally injured during catheter ablation for AV nodal reentrant tachycardia, the symptoms of pseudopacemaker syndrome can be elicited [8].…”

“…The treatment of this symptomatic condition is dual chamber pacemaker implantation (to restore a physiologic AV interval) and it is recommended as level IIA, evidence B as per the device guidelines [9]. Also, the slow pathway modification of markedly prolonged symptomatic first-degree AV block in the setting of dual AV nodal physiology is being recommended as a new alternative mode of management as reported recently [8].…”

The term 'pseudo' means 'false ', 'pretended', 'unreal', or 'sham' and it is likely to be of Greek origin, pseudes means false. There are a number of 'pseudo' terms and syndromes that we see in the practice of cardiology. Even though the meaning of pseudo is unreal or sham, however these syndromes are true entities as described below. These terms appear more 'mimicking' a diagnosis than being truly 'sham'! We attempted to put together most of the 'pseudo'-diagnoses under one heading for reference and convenience. However, every condition cannot be described here in full details and the references are available for further studies.
