Implication
Supports calcium-voltage clock synergy in SAN automaticity under beta-stimulation; hypothesis-generating for human sinus node responses.
Structured PICO
P
Population
Isolated and Langendorff-perfused canine right atria
I
Intervention
Beta-adrenergic stimulation
O
Outcome
Sinus rate, leading pacemaker location, and late diastolic Ca(i) elevation (LDCAE)surrogate
The study demonstrates that calcium and voltage clocks work synergistically to generate sinoatrial node automaticity, with beta-adrenergic stimulation enhancing this interaction.
