Implication

Complete heart block with shifting pacemakers may occur without conduction lesions; leaves open functional mechanisms in unexplained cases.

Key Points

This case study aims to explore the nature and cause of prolonged complete heart-block without observable lesions.
Electrocardiograms were obtained over several months from a hemiplegic patient with complete heart-block.
Histological examinations were conducted to identify organic lesions in cardiac structures.
Atropine tests were performed to assess the effects on heart rates during different respiratory states.
No organic lesions were found in the auriculo-nodal junction or other key areas related to heart conduction.
Ventricular complexes varied frequently, even showing different patterns from beat to beat.
Auricular rate decreased significantly during dyspnea, while the ventricular rate remained relatively stable.

Structured PICO

Population

1 old hemiplegic patient with complete heart block and Cheyne-Stokes respiration

Intervention

Atropine tests (two tests administered)

Outcome

Electrocardiographic changes (ventricular complexes, auricular and ventricular rates) and histological examination of the conduction systemsurrogate

This historical case report demonstrates that complete heart block and shifting ventricular pacemaker complexes can occur without demonstrable organic lesions in the primary cardiac conduction system.
