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.

Expert’S Opinion

AbstractVarying kinds of AV blocks can occur in the setting of myocardial ischaemia or due to degeneration of conduction system. Wenckebach AV block can present with typical Wenckebach periodicity or atypical periodicity. A variant of atypical Wenckebach periodicity may present like Mobitz II AV block. This is called Pseudo Mobitz II AV block. As we are aware that Mobitz II AV block is more dangerous and can suddenly convert into complete heart block, it is essential that we should try to differentiate between Mobitz and Pseudo Mobitz II blocks. Infact atypical Wenckebach cycles are quite common at both AV node and his Purkinje system.

A 53-year-old man was admitted for recurrent syncope and found to have complete heart block (CHB). Cardiac magnetic resonance imaging MRI) showed extensive patchy late gadolinium enhancement in the apical and lateral walls, consistent with cardiac sarcoidosis (CS) but no scar in the septum. A fluorodeoxyglucose (FDG)–positron emission tomography showed FDG uptake in the septum and basal lateral walls. Imaging suggested active inflammation in the septum affecting atrioventricular (AV) conduction but no irreversible fibrosis. Diagnosis of isolated CS requires a high level of suspicion and multidisciplinary teamwork involving heart failure specialists, electrophysiologists and rheumatologists. After specialist and patient discussion, treatment of the disease was initiated with prednisone 40 mg daily, 11 months after presenting with CHB. Three weeks later, ECG with pacing inhibited showed second-degree AV block Mobitz type II and 4 weeks later, AV conduction recovery. This highlights the importance of immediate therapy in reversing AV conduction abnormalities in CS.
