Surface Electrocardiogram

Background: There is growing recognition that congestive heart failure caused by a predominant abnormality in left ventricular diastolic function is common and causes significant morbidity and mortality. Diastolic function usually declines before systolic function, and this precedes clinical signs. 12-lead electrocardiogram is a commonly used tool to assess left atrial enlargement, which is a marker of left ventricular diastolic dysfunction. We investigated the relationship between P wave dispersion, which is easily measured on the surface electrocardiogram and left ventricular diastolic function.Methods: There were 100 patients: 50 with diastolic dysfunction and 50 without. P wave dispersions were calculated by measuring minimum and maximum P wave duration values on the surface electrocardiogram. The relationships between P wave dispersion and echocardiographic measurements of diastolic dysfunction were assessed.Results: Maximum P wave duration was observed significantly (p=0.001) in patients with left ventricular diastolic dysfunction (119.60±8.2 ms vs 114.0±6.4 ms). Minimum P wave duration was observed significantly (p=0.001) higher in patients without diastolic dysfunction (72.6±7.5 ms vs 62.70±7.4 ms). P wave dispersion was observed significantly (p=0.001) higher in patients with left ventricular diastolic dysfunction (56.6±6.3 ms vs 41.5±5.2 ms). When patients were grouped according to grades of diastolic dysfunction, P wave dispersion was observed sequentially increased among 3 grades of left ventricular diastolic dysfunction (55.8±5.2 ms vs 55.9±7.0 ms vs 61.4±4.7) but the differences were not statistically significant (p=0.09).Conclusion: We conclude that P wave dispersion increases in diastolic dysfunction of LV. When clinical and echocardiographic variables are taken into account, there is a weak but significant correlation between P wave dispersion and left ventricular ejection fraction.Cardiovasc. j. 2015; 8(1): 13-18

Background: Patients diagnosed with hypertension will deteriorate into hypertensive heart disease which is characterized by diastolic dysfunction first followed by systolic dysfunction later in the course of the disease. Diastolic dysfunction of the left ventricle causes an increase in LVEDP as well as in the dimension of the left atrium. P-Wave Terminal Force V1 (PTFV1) which is derived from 12 lead ECG could help diagnose diastolic dysfunction in centers where echocardiography is not available. The purpose of this study was to determine the correlation of PTFV1 on the 12-lead Electrocardiography with diastolic dysfunction in patients diagnosed with hypertension in the outpatient clinic of Cardiac Center Adam Malik General Hospital in Medan. Methods: This is a cross-sectional study conducted from March 2019 until August 2019. Patients with hypertension who met the inclusion criteria were examined electrocardiographically to obtain PTFV1 value. Then echocardiography examination was then performed to assess the grades of diastolic dysfunction and other parameters. Analysis of correlation between PTFV1 values and diastolic dysfunction was then conducted. Results: From the clinical characteristics, there is no difference regarding age, sex , and risk factorsbetween the three diastolic dysfunction groups, while echocardiography characteristic shows more reduced EF in grade III diastolic dysfunction (36.5±7.7). Significant differences in PTFV1 are found among diastolic dysfunction groups. Grade I diastolic dysfunction has PTFV1 value of 23.8 mm.ms, grade II diastolic dysfunction has PTFV1 value of 34.1 mm.ms, and grade III diastolic dysfunction has PTFV1 value of 52.1 mm.ms, Significance of  p value is <0.001. There is a strong correlation between PTFV1 and diastolic dysfunction grade (r = 0.63 (P <0.001)). Cut off point of PTFV1 > 29.8 mm.ms can discriminate patients who have increased LAP with a sensitivity of 84% and specificity of 71%. Conclusions: PTFV1 is a simple screening tool which is widely available and correlate well with left ventricular diastolic dysfunction in patients with hypertension, which makes it a good alternative tool especially in areas where echocardiography is not readily available.
