Purpose: To demonstrate the feasibility of mapping intracellular pH within the in vivo rodent heart. Introduction: Alterations in cardiac acid-base balance can lead to acute contractile depression and alterations in Ca2+ signalling. The transient reduction in ATP consumption and cardiac contractility may be initially beneficial; however, sustained pH changes can be maladaptive, leading to myocardial damage and electrical arrhythmias. Methods: Spectrally-selective RF pulses were used to excit...Expand abstract
