| left ventricular failure | <cardiology> A disorder where the left side of the heart fails to pump blood effectively.

Other symptoms include cough, palpitations, fatigue, decreased urine production and waking in the middle of the nigh with difficulty breathing. Complications include pulmonary oedema, arrhythmias and pleural effusion. (27 Sep 1997) |
