One hundred seventy patients with ischaemic heart disease (IHD) and 141 healthy controls were evaluated to assess the diagnostic significance of T I < T III and TV1 > TV6 as compared to widening of QRS-T angle. Number of cases with abnormal widening of QRS-T angle was significantly higher (P < .001) in frontal and horizontal planes in the IHD group. T I < T III sign has 61.2% sensitivity, 74.5% specificity and 25.5% false positivity in diagnosis of IHD. Along with abnormal QRS-T angle widening it gave a specificity of 95.5% but a false positivity of 35% and a low sensitivity index (35.3%). TV1 > TV6 sign has sensitivity, specificity and false positivity of 72.9% 84.4% and 15.6% respectively. Combining it with abnormally wide QRS-T angle did not materially improve these indices. Combining T I < T III and TV1 > TV6 signs gives a sensitivity of 49.4%, specificity of 95% and false positivity of 5% in IHD. This is a good diagnostic index and can be assessed at a quick glance without cumbersome estimation of QRS-T angle. |
