Time-voltage QRS area of the 12-lead electrocardiogram: detection of left ventricular hypertrophy.
Identification of left ventricular hypertrophy (LVH) using 12-lead ECG criteria based primarily on QRS amplitudes has been limited by poor sensitivity at acceptable levels of specificity. Because the product of QRS voltage and duration, as an approximation of the time-voltage area of the QRS complex, can improve accuracy of the 12-lead ECG for LVH, we examined the diagnostic value of true time-...
متن کاملComparative Study of QRS Detection in Single Lead and 12-Lead Electrocardiogram using Support Vector Machine
(ECG) using combined entropy criterion is presented in this paper. The ECG signal is filtered using digital filtering techniques to remove power line interference and base line wander. SVM is used as a classifier for detection of QRS complexes in ECG. Using the standard CSE ECG database, both the algorithms performed highly effectively. The performance of the algorithm with sensitivity (Se) of ...
متن کاملDeriving the 12-lead Electrocardiogram
This paper proposes a lead method and a processing means for monitoring the 12-lead electrocardiogram (ECG) with four standard leads. Leads I, II of the M-L leads and leads V1, V6 of the chest leads are used to record the ECG signals. The ECG waveforms of leads V2 through V5 are derived from the input signals using the least squares method based on the Frank torso model. This method makes it po...
متن کاملRefinement of total 12-lead QRS voltage criteria for diagnosing left ventricular hypertrophy
Objective: We sought to test the hypothesis that the total QRS voltage without either set of the limb leads (I, II, III) or (R, L, F) may be a better indicator of LVH as compared to the total QRS voltage. Background: The total 12 lead QRS voltage has been a validated electrocardiographic criterion for left ventricular hypertrophy (LVH), with an upper limit of 175 mm. However, there is some redu...
متن کاملRecommendations for interpretation of 12-lead electrocardiogram in the athlete.
Cardiovascular remodelling in the conditioned athlete is frequently associated with physiological ECG changes. Abnormalities, however, may be detected which represent expression of an underlying heart disease that puts the athlete at risk of arrhythmic cardiac arrest during sports. It is mandatory that ECG changes resulting from intensive physical training are distinguished from abnormalities w...
