Abnormal or impaired sensation in the heart; a condition of diminished or altered cardiac sensory function.
From cardio- (Greek kardia, 'heart') + dys- (meaning 'bad' or 'difficult') + esthesia (from Greek aisthesis, 'sensation'). Medical term describing disturbed cardiac sensation from 19th-century neurocardiology.
Your heart actually has sensory nerves that can feel pain, pressure, and stretch—cardiodysesthesia means those sensory signals are going wrong, which can lead to confusing cardiac symptoms or angina that feels different than expected.
