Population

Guinea-pig extrapulmonary vein striated muscle fibers

Comparison

Application of cations and catecholamines and… vs Atrial muscle fibers

Design

Preclinical

Discussion

Implication

Adrenergic-evoked extrapulmonary vein activity may trigger atrial arrhythmias; hypothesis-generating in guinea-pig model and leaves open human relevance.

Structured PICO

Population

Guinea-pig extrapulmonary vein striated muscle fibers

Intervention

Application of cations and catecholamines (epinephrine, isoproterenol) and measurement via microelectrode technique

Comparator

Atrial muscle fibers

Outcome

Membrane potentials and action potentialssurrogate

Epinephrine and isoproterenol can evoke pacemaker activity in guinea-pig extrapulmonary vein striated muscle cells, which can propagate retrogradely to the atrium.
