(A) Chart recording of ventricular pressure (Pvem), EMG, and cardiac output (Q) from one semi-isolated heart preparation of Cancer magister showing the presence of double EMG bursts and increased pressure pulses at elevated temperatures. (B) Segments of the same record in A recorded at faster chart speed to show the double EMG bursts and the corresponding increases in Pvem and mean flow. The chart speed was doubled during the last half of the recording at I4°C. The numbers in parentheses above the pressure trace are heart rate, those above the flow trace are Q in ml â min"'..
