We have found that after a prolonged preincubation period (&gt; 6 h), washout of cholinergic agents from embryonic chick hearts or cultured heart cells results in a persistent increase in their basal and catecholamine\u2010stimulated cAMP content. Membranes prepared from pretreated cells have elevated basal, forskolin\u2010, and catecholamine\u2010stimulated adenylate cyclase activities. This myocardial adaptation to cholinergic agents is analogous to changes in nerve cells and other cell types after prolonged exposures to narcotics or other inhibitors of adenylate cyclase, respectively. A rapid (&lt; 5 min) adaptation response to cholinergic agents can also be demonstrated in heart cells by quickly blocking agonist action with atropine. Atropine alone has no effect, but after a brief preincubation period with agonists (methacholine or oxotremorine), the addition of atropine transiently enhances catecholamine\u2010stimulated cAMP accumulation by 2.5\u2010fold. These responses are absent in heart cells pretreated with pertussis toxin. The data indicate that the response is not mediated by the phosphoinositide pathway, which has been demonstrated to be insensitive to pertussis toxin in chick heart. Enhanced cAMP accumulation after termination of muscarinic agonist action may provide an explanation for the observation that acetylcholine sometimes produces biphasic contractile responses.\u2014 L\n                    <jats:sc>inden<\/jats:sc>\n                    , J.
