Division of Cardiology, the First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
The case was a 15-year-old male with a history of paroxysmal supraventricular tachycardia refractory to medical therapy and prior catheter. A repeat electrophysiology study and catheter ablation were applied. Baseline AH and HV intervals were 100 and 55 ms during normal sinus rhythm (NSR), respectively.

Article Synopsis
- Left ventricular hypertrabeculation (LVHT) is a heart condition that can lead to various symptoms, including serious issues like heart failure and arrhythmias, making it difficult to identify which cases are benign versus pathological.
- A study analyzed 140 pediatric patients with LVHT over ten years, and found that 23.6% of them experienced arrhythmias, with various types identified, including supraventricular and ventricular arrhythmias.
- Results indicated a significant relationship between specific genetic variants (class 4 or 5) and the occurrence of arrhythmias, while the patients generally had good outcomes, with no reported sudden cardiac deaths.

Adenosine is a widely used pharmacologic agent in the field of cardiology, predominantly for the termination of supraventricular tachycardias and diagnostic purposes. Most of the side effects are short-lasting due to its very short half-life. Fatal complications of adenosine are rare but can include ventricular fibrillation, ventricular tachycardia, and asystole.

Though permanent pacemaker implantation is the only effective therapy for certain bradyarrhythmias in dogs, it is not without risks. Bacterial infection of the device is one of the most common complications. Human guidelines recommend besides systemic antibiotics, surgical explantation of the pacing lead and pulse generator in case of device-infection.

Unlabelled: In early 2020 Food and Drug Administration (FDA) approved Micra AV - a new type of leadless pacemaker with atrioventricular synchrony, to treat patients with atrio-ventricular (AV) blocks. We describe one of the first in Poland case of a patient who was implanted with Micra AV pacemaker.
Case Report: A 38-year-old female patient was admitted to the clinic due to the 29-seconds event of a complete AV block without an escape rhythm and was implanted with a dual chamber pacemaker without any complications.
