Why the study?
Does an early atrial premature beat alter the activity of the sinoatrial node and atrial rhythm in isolated rabbit right atria?
Does an early atrial premature beat alter the activity of the sinoatrial node and atrial rhythm in isolated rabbit right atria?
Early atrial premature beats can fractionally discharge the SA node and alter spontaneous impulse formation, providing a potential mechanism for reentry and supraventricular tachycardia.
No takes yet. Share an insight, caveat, or question.
May explain reentry initiation by premature beats in rabbit atria; leaves open human translation and clinical relevance.
Bonke et al. (1971) studied this question.
