Heart Rhythm of the Ocean Quahog Arctica Islandica

Abstract. We studied the cardiac activity of the ocean quahog (Arctica islandica) and identified the precise point on the mollusc’s shell at which the heart rate can be successfully monitored remotely. The heartbeat pattern was markedly unstable. Moreover, irregular cardiac arrests were observed in every monitored mollusc. Keywords: Arctica islandica, cardiac activity, heart rat
