The phrase "abnormal waveforms" is correct and usable in written English.
It can be used in contexts related to medical, scientific, or technical discussions, particularly when referring to unusual patterns in data or signals.
Example: "The ECG results showed abnormal waveforms, indicating a potential issue with the patient's heart rhythm."
Alternatives: "irregular waveforms" or "atypical waveforms".
Persistently abnormal waveforms are related to the worst pregnancy outcome.
Abnormal waveforms were recorded by 40 and 12.5% in the study and control groups, respectively.
Results: 88 patients had abnormal waveforms at 24 weeks and 77 delivered after the second assessment at 28 weeks.
Eighteen of the fetuses (36%) had abnormal waveforms, with 8 fetuses demonstrating either absent or reversed end-diastolic umbilical artery blood flow.
In conclusion, these results showed that the interactions of IgG with phospholipids via beta(2) GPI or prothrombin constitute the core mechanisms of the abnormal waveforms.
Based on the detection results, we concluded that the simple and effective selection of preprocessing and decision stages can increase the precision rate of detection of R-peaks in ECG recordings with various normal and abnormal waveforms.
We further visually inspected the waveforms to confirm that this procedure resulted in normal waveforms and the multiunits with abnormal waveform shape were excluded from the analysis.
Prothrombin and beta 2-glycoprotein I frequently contribute to antiphospholipid antibody interactions with phospholipids and the generation of abnormal waveform profiles in coagulation assays.
Three out of 31 knees with atherosclerotic changes showed severe luminal stenosis associated with diffuse atherosclerotic and calcified plaque on Doppler sonography, as well as abnormal waveform patterns on the spectral mode (Fig. 1).
The presence of an abnormal waveform is associated with increased mortality and can be a sensitive and specific indicator of disseminated intravascular coagulation.
However, to our knowledge, no researchers have previously reported the high amplitude of electrical signals or considered that these signals often manifest as an abnormal waveform (such as types III, IV or V).
