Supraventricular tachyarrhythmias pose a significant challenge in neonates and infants, particularly within the first year of life, where prompt and effective management is crucial. By synthesizing available evidence and clinical experience, this review aims to provide a comprehensive overview of antiarrhythmic therapy in this vulnerable population, with a focus on narrow QRS supraventricular tachyarrhythmias. This review examines the current understanding of supraventricular tachyarrhythmia management and discusses the challenges associated with antiarrhythmic therapy in newborns and infants during the critical first year of life, evaluating the efficacy and safety of various antiarrhythmic agents commonly utilized in this population, including dosing considerations, adverse effects, and strategies for acute management and prophylactic long-term antiarrhythmic treatment.

Arrhythmogenic cardiomyopathy (ACM), characterized by fibro or fibrofatty infiltration of the myocardium with a predominant arrhythmic presentation, is a genetically mediated cause of sudden cardiac death in the young and athletic individuals. We report a case of a severe form of biventricular ACM in a middle-aged man with a family history of cardiomyopathy-related young death. The proband was identified to harbor two novel mutations in the DES and DOLK genes and was managed comprehensively with a multidisciplinary team approach. This report reinforces the need for a dedicated cardiovascular genetics program as well as a population-specific genetic database in developing countries.

Background and aim
Cardiac arrhythmia diagnostic yield improves with increased duration of monitoring. We investigated patient comfort, diagnostic quality of ECG, and arrhythmia diagnostic yield using a single lead longer term external cardiac monitor (ECM).
Methods
The observational ECM feasibility study enrolled patients with increased risk of cardiac arrhythmia. The ECM investigational prototype was designed using a chest strap with dry electrodes connected to module capable of triggered loop recording of ECG, and automatic detection of arrhythmia. In group-A of study (24-h inpatient), patients wore ECM and Holter that recorded ECG from the ECM and adhesive electrodes. In group-B of study (12-weeks ambulatory), at monthly follow-ups patients filled out a comfort survey and device stored arrhythmia episodes were reviewed.
Results
The study enrolled 34 patients (38 % females, average age 57.5 years, 65 % had palpitations, 12 % had syncope). Diagnostic quality ECG was recorded on 76.5 % of the monitoring duration in 12 of 20 patients with reviewable data in group-A, with motion artifacts causing loss in ECG signal for 18.7 % of the time. In 14 patients in group-B, 94.9 % of the survey responses indicated that ECM was comfortable to wear. Cardiac arrhythmia was observed in 4 of 17 patients (24 %) in group-A and 9 of 14 patients (64 %) in group-B in device recorded episodes. All ECM detected pause and tachycardia were inappropriate detections due to motion artifacts and temporary device removal.
Conclusion
The chest strap-based ECM device was mostly comfortable to wear and recorded diagnostic quality ECG in three-fourth of monitoring period. Cardiac arrhythmia was observed in 64 % of patients over 3-month monitoring along with large number of motion artifact induced inappropriate detections.

In the setting of ischemic heart disease (IHD), ventricular tachycardia (VT) commonly originates from areas of incomplete scar tissue. High-density electroanatomic mapping has enhanced our understanding of VT circuits, predominantly characterised by dense scar and surviving myocyte bundles. We present a case of a 58-year-old male with IHD and sustained monomorphic VT, successfully treated with radiofrequency ablation following high-density mapping and entrainment techniques. Two inducible VT phenotypes were identified, with ablation at one site effectively terminating both VT morphologies. This case illustrates the importance of precise circuit localisation and targeted ablation in managing post-infarction VT, leading to a satisfactory patient outcome.

A 60-year-old woman presented with recurrent episodes of palpitations, documented short RP, narrow QRS tachycardia and absence of preexcitation in the electrocardiogram during sinus rhythm. During an electrophysiology study, programmed stimulation induced a narrow QRS tachycardia with cycle length of 380 ms, VA interval of 164 ms and earliest atrial activation in the His region. Ventricular overdrive pacing failed to entrain the atrium even with isoprenaline infusion and atrial burst pacing repeatedly terminated the tachycardia. Difference in AH interval with pacing and SVT was 27 msec. Simultaneous atrial and ventricular pacing was done with atrial pacing from the high right atrium and showed a His signal as the first return electrogram suggestive of atrioventricular nodal reentrant tachycardia (AVNRT). The manoeuvre was repeated with atrial pacing from the proximal coronary sinus and showed an atrial signal as the first return electrogram suggestive of atrial tachycardia (AT). What is the explanation for the conflicting results of the two pacing maneuvers?

Introduction: The causes of atrial undersensing in a dual chamber pacemaker include true undersensing (low amplitude electrogram), functional undersensing (related to the effect of special timing cycles in the presence of an adequate signal) and paradoxical undersensing. This case report describes paradoxical atrial undersensing at a higher programmed atrial sensitivity and with the return of normal atrial sensing at a lower programmed sensitivity.

Leadless pacemakers have provided new treatment modalities that can be especially useful in patients with complex cardiac anatomy and contraindications toward other pacemaker approaches. The Aveir™ single-chamber (VR) leadless pacemaker (LP) (Abbott Laboratories, Chicago, IL) is a recently approved device that can be placed in the right ventricle for patients with bradycardia. In this case, we present a novel use for the device through placement in the atrium to control atrial flutter in a patient with a hypoplastic right ventricle.
