“…Several brief reports of inadvertent coronary vein pacing have appeared in the literature. [1][2][3][4] The anatomy of coronary sinus and its major venous tributaries are depicted in Figure 3. Ostium of coronary sinus is situated between the opening of inferior vena cava and tricuspid valve.…”

“…All available 12-lead ECGs were reviewed on each patient for presence of: (a) Left bundle-branch block (LBBB) pattern, i.e., QS configuration in V, and left superior axis deviation in the frontal plane to the paced complexes, rS configuration to the paced complex in V, was also considered to be compatible with LBBB pattern. (b) Right bundle-branch block (RBBB) pattern, i.e., RR, rSR, qR, RS (where R is 20.06 s and R/S is 5 1) and Rs configuration to the paced complexes. QRS…”

Summary:The incidence of inadvertent permanent ventricular pacing from the coronary vein is not known. In a retrospective analysis of 69 patients in whom transvenous pacemakers were implanted between 1979 and 1986, 12 patients were discovered to have right bundle-branch block pattern to the paced complexes on electrocardiogram. In this group, three patients were considered to have inadvertent placement of pacing lead in the coronary vein by twodimensional echocardiographic criteria. No complications were noted in follow-up of 2-79 months. Monitoring of surface electrocardiogram, frontal and lateral fluoroscopy, and pacing threshold and sensing parameters (during implantation of pacemaker) were found to offer no absolute protection against malplacement of the lead. Placement of the lead into the lung field via the main pulmonary artery and then withdrawing with eventual positioning into the right ventricular apex will avoid malposition into the coronary vein. mo-dimensional echocardiography is useful for the diagnosis of pacing lead malplacement and should be performed in any patient with right bundlebranch block pattern in the surface electrocardiogram following pacemaker implantation.

“…Close monitoring and timely intervention are crucial for improving outcomes in patients with CHB complicating leptospirosis. [17][18][19] Patients should also be constantly monitored for any cardiac arrhythmias, renal function abnormalities as well as deranged liver enzymes. In our patient, despite the infection is resolving, the complete heart block persist thus necessitate the need of Permanent Pacemaker insertion.…”

Complete heart block (CHB) is a rare but potentially life-threatening complication of leptospirosis, a zoonotic bacterial infection caused by spirochetes of the genus Leptospira. While leptospirosis primarily affects the kidneys and liver, cardiac involvement, including CHB, can occur and has significant clinical implications. The pathogenesis of CHB in leptospirosis is multifactorial and may involve direct cardiac invasion by Leptospira organisms, systemic inflammatory response, autoimmune reactions, electrolyte imbalances, and hemodynamic effects. Prompt recognition and management of CHB are essential to prevent adverse outcomes, including hemodynamic instability and sudden cardiac death. Treatment strategies include supportive measures such as hemodynamic support and correction of electrolyte imbalances, temporary pacing for symptomatic bradycardia, antibiotic therapy for the underlying infection, and consideration of permanent pacemaker implantation in refractory cases. Cardiac manifestations may include myocarditis, pericarditis, arrhythmias, conduction blocks and cardiac failure. We are reporting a case of leptospirosis causing complete heart block in a previously healthy young gentleman.

A technique for the insertion of an intracardiac electrode through the subclavian vein and implanting the generator in the axilla for permanent endocardia1 pacing is described in 30 patients. Provided that adequate precautions are taken and the procedure is carried out by experienced personnel, complications are uncommon.The generator is implanted after the pacing threshold has been found to be satisfactorily stable. Drainage is not used and routine antibiotics are not given to any patient unless secondary infection of the wound complicates the procedure. Advantages of this technique over the other conventional methods are described.TRANSVENOUS intracardiac pacing has become an established therapeutic measure in the treatment of complete heart block causing Stokes-Adams attacks and congestive cardiac failure (Siddons and Sowton, 1968), in sinus node disease (Reid et al., 1973) and in some cardiac dysrhythmias (Sowton, 1968). At present more than 1800 patients in Britain have implantable mercury-cell pacemakers (Leading Article, 1971). The femoral, cubital, cephalic, external jugular and subclavian veins have been used to introduce the pacing catheter. Each route has its limitations and it is the purpose of this paper to describe the method and value of using the subclavian vein. Patients and methodsPermanent transvenous intracardiac pacing was carried out in 30 consecutive patients suffering from Stokes-Adams attacks due to complete heart block. The age of the patients varied from 46 to 88 years (18 males and 12 females). The pacing catheter was introduced through the subclavian vein by a percutaneous technique and the pacemaker was implanted in the axilla. Postoperative follow-up studies range from 18 to 47 months. The method of venepuncture and the procedure of implantation are described below.
