Localization based on an electrocardiogram (ECG) requires prior acquisition of the patient-specific geometry with the help of tomographic imaging. "Machine learning methods, by contrast, enable identification of the origin of extrasystoles in a non-invasive manner and without tomographic imaging," says...

The other form (type A) occurred after a sequence of more than one conducted sinus beat. The two configurations have previously been explained on the basis of different foci and mechanisms. Certain features of the ECG from our patient suggested that the two forms originated from a common site...
Among SS patients with a history of pericardi- tis, echocardiographic measurements indicated an unexpectedly high frequency of localized hypokinesia of the left ventricle, all with unspe- cific ECG changes, while only one without peri- carditis showed this symptom. No patient had low voltage, ST...
beat is known asventricular trigeminy. VPCs may also occur with no discernible pattern of repetition, as they often do when more than one focus in the ventricles is generating VPCs. If more than one VPC morphology or shape is present on the ECG, they, VPCs, are termedpolymorphico...
The cross-correlation function for alignment of ECG waveforms and rejection of artifacts was studied. ECG waveforms were recorded and digitized (10-bit resolution) at 1.28 KHz and were processed with a CDC 6600 computer. The cross-correlation function was calculated using the cross spectrum and the...
