Deriving 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 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...
متن کامل12-lead surface electrocardiogram reconstruction from implanted device electrograms.
AIM Reconstruction of the surface electrocardiogram (EKG) from voltage recordings from implanted leads is not performed by current pacemakers or cardioverter-defibrillators. We investigated the feasibility and accuracy of reconstruction of a full 12-lead surface EKG from an implanted biventricular device. METHODS AND RESULTS We applied three techniques for surface EKG reconstruction from mult...
متن کاملNew Lessons Learned From the 12-Lead Electrocardiogram
Cardiac resynchronization therapy (CRT) can have a profound therapeutic impact on appropriately selected patients. However, even when the current clinical guidelines for CRT1 are rigorously applied, the response rate is 70%. Nearly a third of patients who undergo implantation of a CRT device are clinical nonresponders and more may be “remodeling nonresponders.” An extensive body of literature r...
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 ...
