Key result
Electrocardiographic parameters including P-wave dispersion, QT interval dispersion, QRS intrinsic deflection, Tpeak-Tend duration, and fragmented QRS show potential as non-invasive diagnostic markers for Coronary Slow Flow Phenomenon.
Why the study?
Coronary angiography is the only effective way to detect CSFP but is invasive, costly, and carries contrast risks, prompting interest in ECG as an inexpensive, non-invasive alternative.
Does electrocardiography have predictive value for detecting Coronary Slow Flow Phenomenon compared to coronary angiography?

ECG parameters such as p-wave dispersion and QT interval dispersion may offer a non-invasive, inexpensive alternative for the early detection of Coronary Slow Flow Phenomenon, though further studies are needed.
Coronary Slow Flow Phenomenon (CSFP) is characterized by the slow flow of contrast in one or more epicardial coronary vessels without evidence of coronary artery stenosis during coronary angiography procedures. CSFP is fairly common at the time of elective angiography with an incidence of around 7% and accounts for about 4% of hospitalized unstable angina cases. Coronary angiography is currently still the only effective way to detect CSFP, but this procedure is an invasive procedure with high costs, there is a risk of allergy to contrast. Electrocardiography (ECG), as a widely available, inexpensive, and simple modality is felt to be an attractive alternative in early detection of this abnormality. The ECG parameters on CSFP discussed in this study include; p-wave dispersion, QT interval dispersion, QRS intrinsic (Tpeak-Tenddeflection duration), and QRS fragmentation. Further studies are needed on the ECG image in CSFP so that in the future ECG can be a cheaper and non-invasive diagnostic modality for CSFP compared to coronary angiography.

Sukandi et al. (2022) conducted a review in Coronary Slow Flow Phenomenon. Electrocardiography (ECG) parameters was evaluated. Electrocardiographic parameters including P-wave dispersion, QT interval dispersion, QRS intrinsic deflection, Tpeak-Tend duration, and fragmented QRS show potential as non-invasive diagnostic markers for Coronary Slow Flow Phenomenon.
