Value of the electrocardiogram in identifying heart failure due to left ventricular systolic dysfunction: Table 1

Chronic heart failure due to left ventricular systolic dysfunction has a high morbidity and mortality. Angiotensin converting enzyme inhibitors reduce symptomatic deterioration, hospitalisation, and death. Most patients with suspected heart failure present first to general practitioners. Recent studies have emphasised the difficulty of diagnosing heart failure in the community. Fewer than half of patients treated for heart failure by general practitioners have objective evidence of cardiac disease.1 2 To improve diagnosis and treatment Dargie and McMurray suggested that echocardiography should be performed in all patients suspected of having chronic heart failure.3 Screening patients before referral for diagnostic investigation may lessen the considerable resource implications of this approach. We assessed the value of the electrocardiogram in identifying patients with possible chronic heart failure. An open access echocardiography …
