case_images: The electrocardiogram (ECG) post-pacemaker implantation demonstrates VAT pacing mode with an atrial pacing rate of 60 beats per minute. The ECG indicates effective atrial sensing, atrial triggering, and ventricular sensing without ventricular pacing

case_images: Post-implantation, the electrocardiogram (ECG) showed AAI pacing mode (Fig. 1).
case_images: Panel A: An overall view of the patient's chest, showing the location of the pacemaker. Panel B: A close-up of the pacemaker pocket. The images reveal a pacemaker pocket infection with exposed leads and visible skin necrosis around the area, indicating a severe infection

case_images: Despite antibiotic treatment at a local hospital, the infection persisted (Fig. 2).
case_images: Recurrent ventricular tachycardia during the CCU hospitalization following pacemaker infection. The ECG tracings, recorded in standard lead II, highlight multiple episodes of ventricular tachycardia, indicating the severity of the arrhythmia associated with the pacemaker infection

case_images: ECG indicated recurrent VT (Figs. 3 and 4).
case_images: Standard 12-lead electrocardiogram (ECG) recording of a ventricular tachycardia (VT) episode in the patient. The VT has a rate of approximately 190 beats per minute. In lead I, the QRS complex displays an R-wave pattern. Leads II, III, and aVF show predominantly positive QRS complexes with the main deflection being upward. The precordial leads (V1-V6) indicate an early transition, characterized by the shift of the QRS complex to a predominantly positive direction earlier than expected, suggesting the VT may originate from a location other than the typical right ventricular outflow tract (RVOT)

case_images: ECG indicated recurrent VT (Figs. 3 and 4).
case_images: Panel A: Parasternal short-axis view of the great arteries. Panel B: Parasternal long-axis view of the left ventricle. In both images, the blue arrows indicate the ventricular lead, while the star symbol marks the free wall of the right ventricle. The images demonstrate that the right ventricular lead is positioned at the free wall of the right ventricle, which is identified as the origin of the ventricular tachycardia

case_images: Echocardiography (Fig. 5) and chest X-ray (Fig. 6) confirmed that the ventricular lead was positioned at the free wall of the right ventricular outflow tract, where the VT originated.
case_images: Panel A: Extraction process of the right ventricular pacing lead. The lead is unscrewed from the myocardial tissue by rotating it counterclockwise and then gently pulled out of the body. Panel B: Extraction process of the right atrial pacing lead. After the right ventricular lead has been removed, the right atrial lead is similarly rotated counterclockwise to disengage it from the atrial myocardial tissue and then carefully pulled out of the body. The blue arrows in both panels indicate the direction in which the leads are being pulled out of the body

case_images: The extraction process involved counterclockwise rotation to detach the leads from myocardial tissue (Fig. 7).
case_images: ECG following the removal of the pacemaker leads. The ECG displays a sinus rhythm with a heart rate of 52 beats per minute. There are no episodes of ventricular tachycardia or ventricular premature contractions observed
