ECG Wave Pattern Strip for Ventricular Fibrillation ECG (electrocardiogram or EKG) of VFib shows only fast irregular electrical tracings with no tracings showing a QRS (the large “spike” pattern on a normal ECG) indicative of a heartbeat (ventricular contraction). Subscribe to MedicineNet's He...
Atrial Fibrillation ECG Wave Strip Pattern What does atrial fibrillation look like? AFib is a type of arrhythmia termed supraventricular tachycardia, meaning that the problem occurs above the ventricles. For AFib, the abnormal heart rhythms are due to irregular electrical activity in the atria, mainly...
Figure 4. Strip plots of the R-R intervals for all 23 subjects. 2.3. Outlier Removal Based on Figure 4, it was apparent that the R-R intervals of many subjects contained extreme outliers. These outliers were most likely caused by noise, and were, thus, filtered from the data. The fil...
