Abstract Atrioventricular junctional ablation is an attempt to interrupt conduction from the atrium to the ventricle using radiofrequency energy. The objective is to ablate the compact atrioventricular node as high as possible, leaving a stable ventricular escape rhythm. The compact node is identified in part by its relation to His recordings and partly through the known anatomy. In our series of 115 consecutive patients, atrioventricular block was achieved from the right side in 96% of patients and the remainder had the atrioventricular node ablated from the left side. Long-term success, i.e. complete heart block, was achieved in all patients. Complications in this and other series are rare, but there remains concern about sudden death in these patients.

Mill Test

: We present a case of 75-year-old lady with effort intolerance and baseline ECG showing 2:1 atrio-ventricular block, in whom it was unclear as to requirement of permanent pacing, even after long term ECG monitoring. She underwent a tread mill test during which her QRS became wide and developed complete heart block within 2 minutes of the test. Thus, a simple exercise test helped in confirming level of block to be infra nodal without need for invasive study. In patients with exertional symptoms, even in elderly, and in those where ECG masquerades as a benign entity, exercise testing is useful to differentiate benign cases of atrio-ventricular block from the more serious cases that mandate a pacemaker implantation.

Abstract A young child presented with hepatomegaly, ascites, and bradycardia in the setting of coronavirus disease-2019. Permanent complete atrioventricular block and severe right heart failure were diagnosed. He was treated with surgical epicardial pacemaker implantation. This report is the first description of coronavirus disease-2019–induced permanent complete atrioventricular block in a child.

A previously well 48-year-old man presented with presyncope and was found to be in complete heart block. Blood tests, echocardiography and coronary angiography were reported as normal, and a dual chamber permanent pacemaker was inserted. Six months later he re-presented with breathlessness. His chest X-ray showed cardiomegaly and echocardiography revealed a 4.4 cm pericardial effusion. A CT thorax revealed a mass originating from the intra-atrial septum, extending into the right atrium and ventricle. There were multiple pulmonary lesions suspected to be metastases. Histology demonstrated high-grade B-cell lymphoma. He was treated with eight cycles of R-CHOP chemotherapy and showed good radiological and clinical improvement. Post-treatment echocardiography found severe left ventricular dysfunction with an ejection fraction of <20%. Heart failure medical therapy was optimised and the pacemaker was upgraded to a resynchronisation device. A repeat scan 6 months post device upgrade showed an improvement in ejection fraction to 45%–50%.

Degree Heart Block

In spite of general complacency about first-degree heart block in acute rheumatic fever, abnormal conduction with dysrhythmias, occasional complete heart block, and, rarely, Stokes-Adams attacks are important early signs of acute rheumatic fever and may precede other signs. Every person with episodic fainting is entitled to an ECG, and frequent ECGs are imperative in any case of rheumatic fever with signs of arrhythmias. Changing atrioventricular block necessitates continuous monitoring for dysrhythmias. A 13-year-old boy who appeared with Stokes-Adams attacks secondary to acute rheumatic fever was successfully treated by temporary pacing.
